Abstract:

Ten physicochemical and nutritional quality traits (100-seed weight, seed volume, seed density, bulk density, hydration capacity, hydration index, swelling capacity, protein, tryptophan and energy value) were examined in the seed samples of parents, F_2 and F_3 generations of three microsperma × microsperma and two microsperma × macrosperma crosses of lentils. Significant variation for different traits was observed among the genotypes in both the groups and also among both types of crosses in F_2 and F_3 generations. Ranges, means and coefficients of variation (CV %) for various traits among parents, F_2 and F_3 generations of different crosses, along with the deviations between F_2 and F_3 generation means for various traits in different crosses are discussed. Also suggested is a breeding strategy for evolving lentil varieties with improved seed yield and nutritional quality parameters.
