MMG 7621: PLANT BREEDING
|
THEORY: Goals of breeding, Reproductive and population control in plants, Incompatibility systems: Gametopytic, Sporophytic and heteromorphic, Male sterility systems: cytoplasmic, Genic, cytoplasmic-gnic. Selection under self fertilization, Genetic consequences of hybridization. Role of genotype and environment in continuous variation, Theory of meting and their genetic consequences, Genetic basis of inbreeding depression and heterosis, Breeding plans or self & open pollinated population: pure line breeding and Mass selection, Pedigree method, bulk population method, Back cross breeding hybrid varieties, Recurrent selection and synthetic varaties, Breeding for diseases and insects resistance PRACTICAL: Study floral biology of economically important plants of season, Pollination techniques: emasculation & pollination by different methods, Problems involving self & cross incompatibility systems gametophytic & sporophytic, Study of phenotypic, genotypic and environmental variances, Estimation of habitability and genetic advance under selection. Experiments with pollen morphology and germination, Estimation of inbreeding depression and heterosis in cross pollinated crops. |
