CR319 PLANT BREEDING AND GENETICS III
SECTION 1: Genetic fine structure. The bar
locus, pseudoalleles an complex loci, complementation
mapping, the rII locus. Operon models in Procaryotes, Bacterial promoters,
Gene control
models in Eucaryotes.
SECTION 2: Recombinant DNA technology; Restriction
endonucleases, DNA cloning, Nucleic acid
hybridization, Genetic basis of RFLP. Genetic basis of RAPD,
The polymerase chain
reaction (PCR).
SECTION 3: Molecular markers in plant improvement:
-
RFLP markers in plant breeding Isozymes in plant breeding,
Transposable elements in plant breeding.
SECTION 4: Introduction to the theory of selection.
What is selection, response to selection and its
prediction, selection differential and intensity, effect of selection
on variance.
SECTION 5: Quantitative Inheritance
-
Population mean, Average effects. Breeding value, Dominance
deviation, Interaction deviation, Genetic components of variance.
SECTION 6: Mating and evaluation designs
-
Mating designs e.g. diallel mating design, North Carolina
designs.
-
Evaluation designs, Field -- Plot techniques
SECTION 7: Population genetics
Changes in gene frequencies:
-
Mutation rates
-
Selection
-
Fitness
-
Gametic selection
-
Zygotic selection
-
Heterozygous advantage
SECTION 8: Plant Breeding Seminars
1. Genetic variability
for disease resistance in -
(a) pathogenic fungi, and
(b) host species
2. The future of plant breeding.
