Abstract

  The field experiment was conducted to investigate morphological, growth, biochemical, yield attributes and seed yield in six Brassica juncea mutants viz., MM 01, MM 02, MM 04, MM 08, MM 09 and MM 10 along with a cultivar, BARIsarisa-11. Results revealed that high yielding genotypes had higher morphological characters (plant height, branch number and leaf area), growth characters (leaf area index, total dry mass and absolute growth rate), biochemical parameters(total sugar, nitrate reductase and photosynthesis) and yield attributes (siliqua number, siliqua length, number of seeds siliqua-1 and 1000-seed weight) resulting higher seed yield than low yielding ones. High yielding genotypes also showed better assimilate partitioning to economic yield than low yielding ones. The mutants MM 10 and MM 02 showed superiority in respect of growth and biochemical parameters resulting superior yield attributes thereby seed yield (2533 and 2417 kg ha-1, respectively). In contrast, MM 09 showed the inferiority in case of growth, biochemical parameters and siliqua number and also showed lower seed yield (1767 kg ha-1).
