Definition of Plant and animal breeding: introduction, hybridization-inbreeding and outcrossing, hybrid and hybrid vigour, pureline, inbred line, manifestation of heterosis, consequences of inbreeding, selection and selection methods-mass and pureline selection; genetic basis of inbreeding in plants and animals; concept of heritability and genetic gain. Method of reproduction in plants; features that dictate mode of pollination in plants: crosses- main selection, recurrent selection, hybrid/synthetic varieties, meaning of protogamy, self-incompatibility, male sterility, floral devices, monoecy, dioecy; self-pollinating crops-meaning of autogamy, pureline breeding, bulk population breeding, pedigree breeding, backcross breeding, cleistogamy, apomixes, parthenocarpy. Breeding methods in plants – conventional; plant introduction, hybridization and selection, non-conventional: mutation, tissue culture and genetic engineering; polyploidy, aneuploids, euploids in plant breeding. Concept of disease and insect resistance – horizontal resistance, vertical resistance, tolerance, hypersensitivity, immunity; Breeding methods that can incorporate resistance in crop in plants – backcross breeding, pedigree breeding, genetic basis of backcross breeding, advantages/disadvantages of both.
