Cholani Weebadde is an Assistant Professor and the Plant Breeder for International Programs at Michigan State University (MSU). She works with MSU plant breeders to take their research beyond the borders of the United States. She brings together qualified international partners for collaborative research, education and outreach programs. Support for her current work in Africa and Asia comes from the Bill & Melinda Gates Foundation, USAID, USDA FAS, MSU AgBioResearch and National programs. Her lab currently focuses on soybean (Gycine soja), white yam (Dioscorea rotundata), potato (Solanum tuberosum), bean (Phaseolus vulgaris), rice (Oryza sativa) and strawberry (Fragaria ananassa) breeding and research. Weebadde has a keen interest in DNA Nanobiosensor technologies for further expanding her research and connecting networks in the developing world through citizen scientists and big data.
Weebadde’s approach to research is to develop and implement programs that involve multiple partners for mutual benefits to Michigan/U.S. agriculture and international agriculture. The international collaborative partnerships will not only help build human capital and local capacity but also will enhance opportunities for exchange of germplasm, expertise, and attract new funding for MSU. These collaborative opportunities will also open doors for addressing problems that are common to Michigan/U.S. agriculture and international agriculture such as drought and cold tolerance, resistance to insects and diseases, and enhancing nutritional quality.
Collaborative research on Strawberry breeding
Michigan State University has an excellent strawberry breeding program. With the intention of expanding the germplasm pool, Prof. James F. Hancock (MSU’s former strawberry breeder) selected progenitor species of cultivated strawberries and recreated the original hybridization that led to the cultivated strawberry. His crossing and selection process has thus generated breeding populations that segregate for a number of agronomic traits important for breeders.
With her keen interest in taking strawberry research across the borders of Michigan and the United States, Cholani has initiated a tropical strawberry breeding program at MSU. She also conducts collaborative research with Jagro Strawberry Industries in Sri Lanka to test several of MSU’s advanced strawberry lines in tropical climates. She continues to use Dr. Hancock’s germplasm in the hope of develop better varieties. While the collaboration with Jagro would allow MSU to test adaptation of it’s advanced strawberry lines in tropical climates, it would also allow Jagro Strawberry Industries to improve their breeding program by having a diverse germplasm base.
Collaborative research on dissecting yam reproductive biology for improving the breeding efficiency in White Yam (Dioscorea rotundata)
White yam is an important food security crop for West Africa. However, there is limited research being conducted on this important species outside Africa where sophisticated facilities are available at fingertips. As a step towards building the yam breeding and research community in the US, Weebadde lab collaborates with the International Institute of Tropical Agriculture (IITA) and yam breeder in Ghana to understand constraints faced in yam improvement. Among the least understood in yam breeding is factors that trigger plants to flower. Currently, yam breeders are unable to predict crosses, as there is no guarantee that a specific line would flower or not. Furthermore, a breeder is also not certain whether a specific accession of yam would produce male or female flowers. Some suggest that the sex of the yam plant depends on the set size that is planted. Others believe it may be linked to soil fertility, as yam planted in newly cleared forestland tends to flower intensely. Weebadde lab is conducting collaborative research with research institutions in West Africa to dissect yam reproductive biology with the intention of improving the efficiency of crop improvement. As a member of the Center for Genomics Enabled Plant Sciences (CGEPS) at MSU, she partners with Kevin Childs for her research on flowering of white yam.
MSU AgBioResearch supported her initial research on white yam.
Collaborative research on green bean for tropical climates
Michigan State University is the home to the nation’s #1 dry bean (Phaseolus vulgaris) breeding and genetics program. A number of tropical countries around the world use the same species (Phaseolus vulgaris) but harvest the immature pod (versus the dried pos or seed) commonly referred to as the green bean, string bean, snap bean, Italian Romano bean, yellow wax bean or the purple podded bean. These beans are grown as bush types or pole types. While bush types (determinate growth) are common in the US, many tropical countries use the pole types (indeterminate growth) as they yield more and can be continuously harvested. However, the diseases that affect the species tend to be the same. Therefore, disease resistant germplasm developed at MSU could become useful in improving breeding programs in the developing world.
In 2017, Weebadde initiated a Sandwich PhD degree program with the Department of Agriculture in Sri Lanka to develop rust resistant snap bean varieties. Through collaborations with Dr. Talo Pastor-Corrales, a well known USDA pathologist, her student is making breeding crosses to incorporate rust resistance genes into the susceptible varieties in Sri Lanka.
This Sandwich PhD degree program serves as a model to build capacity at National Agricultural Systems (NARs) and Agriculture Universities in developing countries to conduct research on crop breeding in the hope of transferring MSU’s wealth of plant breeding knowledge across the borders.
Collaborative research on Potato breeding for resistance to Nematodes
Together with Prof. Dave Douches (MSU Potato Breeder) and Prof. George Bird (Department of Entomology at MSU), Weebadde lab is also collaborating with Kyrgyzstan in Central Asia to understand how well MSU’s potato lines would perform on soil that is naturally infested with nematodes. This research is of particular interest to scientists in Kyrgyzstan where potato production is severely hampered by nematode infestations. Their interest is to have access to potato varieties that re resistant to nematodes. Ms. Saltanat Mambatova (MSU PhD student originally from Kyrgyzstan and formerly with Prof. Douches for her masters degree) has been working closely with the Weebadde lab for conducting the research work. Given that nematode infestation in potato fields has zero tolerance in the US, this opportunity provides a win win solution to testing MSU’s potato lines for nematode resistance and also to assist Kyrgyzstan have access to better potato varieties for farmers.
USAID Feed the Future Biotechnology Potato Partnership (FtF BPP) Project (2015 – 2020)
Weebadde serves as the Human and Institutional Capacity Building (HICD) Lead for the FtF BPP Project at MSU. The project works on developing genetically engineered late blight resistant potato to be tested and evaluated for commercial release in Bangladesh and Indonesia towards the end of the project. Weebadde is responsible for developing an HICD strategy for the partner countries and organizing training programs for the project teams. She visited both countries to conduct a baseline survey of human and institutional capacity in February 2016. Based on this, a series of training programs were developed and offered at MSU and in-coutry. Fore more information please visit: https://www.canr.msu.edu/biotechpp/
Collaborative research project for tropical soybean breeding
Dr. Dechun Wang’s soybean breeding program at Michigan State University has produced invaluable germplasm resources that is being used by the soybean industry in the US. The knowledge and experience of Dr. Wang on soybean breeding can benefit a large number of soybean breeding programs around the world. Therefore, with his advise and in collaboration with the Department of Agriculture (DoA), Weebadde lab is assisting to enhance the Soybean breeding program in Sri Lanka. At the onset, with the help of Dr. Randy Nelson, steps were taken to improve the germplasm base of the breeding program by taking 77 soybean genotypes to Sri Lanka from the USDA Soybean Repository in Illinois. Soybean field trials were conducted at Mahailluppallama to evaluate performance and agronomic traits of the 77 lines together with 3 DoA recommended varieties. First trial was conducted in January 2015. Based on the performance of these lines, it was evident that maturity groups VIII and IX perform better compared to the DoA recommended varieties in Sri Lanka. Therefore, along with the 77 initial genotypes, an additional 30 genotypes of the maturity groups VIII and IX were directly sent to DoA from the USDA Soybean Repository in October 2015 for 2016 trials. A total of 107 lines were tested in the field in January 2016 and June 2016. Based on the performance of all three trials, superior types will be selected for making crosses in the next season.
Additionally, steps are being made to transfer MSU’s Round-up Ready soybean germplasm resources to Uganda for conducting confined field trials.
DNA Nanobiosensor technology for Collaborative research with Citizen Scientists around the world
In collaboration with Prof. Brad Day and Prof. Dave Kramer from MSU and Dr. Lava Kumar from the International Institute for Tropical Agriculture (IITA) and Photosync LLC., Weebadde is seeking opportunities to engage farming communities in the developing world as citizen scientists for early detection of plant diseases. The initial focus of the work is to have a system in place to detect plant pathogens before disease symptoms appear and the focus is on staple food crops of Africa.
Collaborative research on Cowpea breeding
In 2008 she was also involved in assisting the Department of Agriculture (DoA), Sri Lanka to expand their cowpea breeding program. Working with the former IITA cowpea breeder, Dr. B.B. Singh, she transferred improved cowpea varieties to be tested in Sri Lanka. The better performing lines were selected and were incorporated into the breeding program. Two of the lines are nearing release.
People (Lab members)
Agus Hasbiento (Graduate Assistant)
Agus comes to MSU from the Indonesian Agency for Agricultural Research and Development (IAARD) in Indonesia. He is interested in developing tropical soybean varieties tolerant to acidic soils in Indonesia. His research outcomes are targeted towards expanding the soybean growing areas in Indonesia in to Kalimantan region where soil acidity is currently limiting expansion. Through greenhouse experiments at MSU, he screened over 700 soybean germplasm accessions obtained from USDA and selected 20 lines that were field trialed in Indonesia in Summer 2017. The 20 lines will be replicated in multi location trials in summer 2018.
Eric Owusu Danquah (Graduate Assistant)
Eric is a USAID BEHEARD Scholar from Ghana. He comes to MSU from the Crops Research Institute (CRI) of the Council for Scientific and Industrial Research (CSIR) in Kumasi, Ghana. Eric’s research focuses on white yam (Dioscorea rotundata), a staple food security crop in West Africa. His research is farmer centered and focuses on improving soil nutrition and providing better options for staking as a way of bringing down production cost of white yam in Ghana. He is currently exploring how a yam/pigeon pea cropping system would benefit yam growing farmers in Ghana.
His research activities are currently supported through a grant btained from the Alliance for African Partnerships (AAP) at MSU.
Weebadde believes in exchange of knowledge and information with others to build the next generation of leaders in genetics, plant breeding and biotechnology. She teaches the Plant Breeding and Biotechnology (CSS 441) course at MSU in the spring of even years. Given that this course requires the knowledge of basic genetics, she has took the initiative to develop short lessons for students to review basic genetics concepts prior to coming to class. These primers are publicly available to students and educators around the globe and can be accessed at:
Weebadde also teaches New Horizons in Biotechnology (CSS 222) in Fall of every year starting 2017. Prior to this she has also taught CSS 350 – Introduction to Plant Genetics at MSU in 2012 and 2013. In 2014, she co-taught this course with Dr. Eric Olson. She also gives guest lectures in other CSS courses (CSS 431 and CSS 120) for undergraduates.
In 2009, Weebadde designed and launched an annual short course on Molecular Plant Breeding to share MSU’s wealth of experiences in marker-assisted breeding with the international community. Given that students in the MSU Plant Breeding, Genetics and Biotechnology (PBGB) program could benefit from this course as well, she included sessions for international plant breeders to present their research work at the course as a means of bringing case studies of globally important food security crops that may not be grown in Michigan (eg. rice, sorghum, pearl millet, cassava, tef) to MSU’s classrooms. She partners with a number of plant breeders at MSU and resource faculty from CGIAR centers and other countries to offer this course annually at MSU as well as in international settings (Ecuador, India and Sri Lanka).
In addition, she continues to give lectures on various aspects of Plant Breeding as well as on the regulatory and policy areas of biotechnology in other short courses organized by the World Technology Access Program (WorldTAP) at MSU. She also utilizes electronic means to deliver lectures to the international plant breeding community.
As a graduate student at MSU (2000 – 2005), Weebadde served as a teaching assistant for ZOL/BOT 341, an undergraduate course in Fundamentals of Genetics for two semesters. She also tutored three athletes at MSU for this course for an additional semester. During this time, on the recommendation of Dr. Barbara Sears (Instructor for ZOL/BOT 341), Weebadde volunteered to develop a Test Bank for teaching genetics at the College level for Freeman and Company in 2004. In addition, she taught the PLB 800 section 2 – Techniques in Plant Molecular Biology to graduate students. She also followed course work and seminars offered for the MSU Certification in College Teaching.
Prior to joining Michigan State University, Weebadde served as a teaching assistant and lecturer at the University of Colombo, Sri Lanka where she taught a variety of laboratory classes to undergraduate students in plant sciences.
Weebadde has been serving as the Associate Director of the World Technology Access Program (WorldTAP) of College of Agriculture and Natural Resources (CANR) since 2006. As a member of the WorldTAP team, she provides leadership for education and capacity building programs in plant breeding and biotechnology as they relate to international agriculture development. Embedded in these programs are collaborative research, training and resource network building in the areas of Marker Assisted Breeding (MAB) and Genetic Engineering for crop improvement. These programs are offered in collaboration with MSU faculty across various departments as well as resource faculty from other organizations outside MSU. Through these programs, the team has trained more than 500 scientists and professionals from over 50 countries creating an excellent network, which brings multiple benefits for MSU breeders, biotechnologists and other scientists. The approach to international collaborative research has been to design and implement programs that involve multiple partners and project teams across institutions for mutual benefits to Michigan agriculture and international agriculture.
As a part of the global outreach program, Weebadde has gained experience in conducting training, education and needs assessments in a number of countries. She was a member of the team that conducted needs assessments in Bangladesh, Ethiopia, Indonesia, Mali, Nigeria and Sri Lanka, which allowed her to gain a deeper understanding of the real needs on the ground, key areas for research, training and education as well as the local capacity. This understanding is critical in developing a road map for successful capacity building and collaborative programs. Through the training and outreach programs of WorldTAP, MSU has reached out to more than 2000 stakeholders in over 125 countries around the world. In addition, Weebadde served as the Extension/Outreach Team Lead for the USDA-NIFA funded RosBREED Project, a Coordinated Agriculture Project (CAP) for enabling marker-assisted breeding in Rosaceae crops.
Weebadde has utilized multiple approaches for outreach and extension activities ranging from workshops, “seeing is believing” study tours, training of trainers (ToTs), laboratory/field visits and on-farm demonstration plots, short courses, seminars, forums, side events at conferences, industry roundtables, farmer field days as well as electronic means to facilitate two-way exchange of information, experiences and ideas for mutual benefits. Having multiple approaches for outreach is particularly important when working with diverse groups of stakeholders especially on controversial areas such as genetic engineering where there is much misinformation, myths, or lack of evidence-based information. For example, projects that involve building functional biosafety regulatory systems not only require training and educating regulators to make science-based informed decisions but also require educating other stakeholders who influence policy and decision-making such as politicians, lawyers and farmers some of whom have never seen a genetically engineered crop growing in the field. Many of these high-level stakeholders gain a better appreciation of new technologies when they see it out in the field. Therefore, “seeing is believing” study tours and meeting with farmers growing GE crops are often better options for reaching out to these groups. At MSU, as a part of international biotechnology training courses, team WorldTAP implemented a “Transgenic Teaching Garden” for participants to see the technology in the field. The team also provides them opportunities to interact with Michigan farmers who grow GE, non-GE and organic crops.
To offer various outreach programs around the world, team WorldTAP developed partnerships with other universities, CGIAR international centers, private sector, regulatory agencies (EPA, FDA and USDA-APHIS), Non-Profit organizations (eg. Danforth Center), NGOs (eg. IFIC), Farmer organizations (eg. CAIF) as well as worked in close collaboration with specialists from US and other countries. WorldTAP has also strongly encouraged south-to-south collaborations for knowledge and technology transfer. These partnerships not only broaden MSU’s network but also provides an excellent platform for continuing exchange of information, experiences and ideas as we move towards building global knowledge societies.
To support and sustain international programs, she has been successful in attracting funds from various external sources. In this process, she has gained considerable experience in development of proposals and building a donor network that includes government agencies, private foundations as well as private companies. Currently she serves as a Co-PI on a grant at MSU from the Bill and Melinda Gates Foundation. She has also been PI and Co-PI in other grants funded by the USDA-FAS, USDA-National Institute for Food and Agriculture (USDA-NIFA) and USAID. In addition, she has attracted a number of research and training fellowship grants from diverse sources including the World Bank, Kirkhouse Trust in UK, ICGEB in Italy, and IUSSTF in India.
Since joining WorldTAP in 2004, Weebadde has traveled to over 25 countries around the world for capacity building activities. Through these travels, she has realized the role that outreach plays in the success of agricultural research and development by reaching out to farmers, policy makers and other stakeholders.
To further expand international programs in plant breeding, Weebadde hopes to use existing platforms and the strength of the PBGB program to make MSU programs more visible to the international community. In doing so, she wishes to engage MSU’s Alumni network across the globe in win win collaborative research in an effort to reverse “brain drain” to “brain gain”.
