Genetic Study for seed yield ans seed quality traits in Indian mutsrad [Brassica juncea L. Czern & Coss.]
Abstract
Combining ability, gene action and heterosis was studied in a set of seven parental lines, five tester and their hybrids of Indian mustard following a L x T mating design. The parents CJ 3761, DRMR-659-49, ZEM 1, ZEM 2, GM 1 and GM 3 were good combiners for seed yield per plant. ZEM 1 was found good combiner for number of branches per plant, number of siliquae per plant and linolenic acid. ZEM 2 good combiner for erucic acid and linolenic acid; GM 1 was found good combiner for decrease the erucic acid. The cross CJ 3761 x GM 3 registered high per se performance, standard heterosis and sca effects for seed yield per plant. This involved both good general combining parents. Considering mean performance, heterosis and combining ability effects, the parents CJ 3761, DRMR-659-49, ZEM 1, ZEM 2, GM 1 and GM 3 and the hybrids CJ 3761 x GM 3, ZEM 2 x Kranti and DRMR-659-49 x GM 2 were found to be promising for the development of high yielding genotypes.
