ABSTRACT
In advanced segregating generations, variability was studied and compared in 14 mustard crosses, for yield and its attributing traits. The fourteen crosses in the F4 generation in the first year and F5 generation in the second year differed significantly for all characters except total chlorophyll content, 100 seed weight and secondary branches per plant and seed yield per plant in F4 and total chlorophyll content and 100 seed weight in F5 generation. In F4 generation Pusa Bold × Pusa Bahar was the highest yielder (10.62 g/plant) but in F5 generation Pusa Bahar × Varuna (10.25 g/plant) was the highest yielder. At both genotypic and phenotypic level, seed yield per plant was positively associated with plant height, height upto first fruiting branch and siliquae per plant only in F5 generation whereas, in F4 generation no such positive association on seed yield component with seed yield per plant was found. In F5 generation, seed yield was positively associated with plant height, height upto first fruiting branch and siliquae per plant. On the basis of the mean performance of the crosses F5, three of them namely Pusa Bahar × Varuna, Pusa Bold × Kranti and Pusa Barani × Pusa Jaikissan were identified as high yielding and can be used for further selection of superior high yielding genotypes of mustard.
