Abstract:In any crop improvement programme, when ever individual plant selection for a particular characters are made in the segregating generations, it is usually accompanied with changes in the related characters. Therefore, it is imperative to know the role of component characters in the selection experiments aimed to increase seed yield.
The breeding methods viz., unselected bulk, bulk S.S.D. (Single siliqua per plant) and pedigree were compared for five characters, viz., number of primary branches, number of secondary branches, seeds/ siliqua, 1000 seed weight and seed yield (plant in four crosses viz. Narendra Rai × NDR 8220, Narendra Rai × NDR 8208, Narendra Rai × NDRE 4 and Vardan × Kranti of Indian mustard (Brassica juncea L. Czern & Coss). was compared. All the crosses showed significant differences among their progenies under all the methods for the five characters studies. Progenies from pedigree were found to have better mean, range, heritability and genetic advance for majority of characters. Pedigree and SSD proved to be better method in identification of early progenies in different population.
