GAMMA-RAY INDUCED BOLD SEEDED MUTANT IN VIGNA MUNGO (L.) HEPPER

Abstract

A vigorous and bold seeded mutant was isolated from M2 progeny of 20 kR gamma-ray irradiated plant population of Vigna mungo cv. T-9. The mutant had larger leaves and flowers similar to control but upper part of style and stigma of each flower was cu:ved. The mutant had larger and healthy pods bearing bolder seeds and showed higher seed yield/plant. Cytologically, it showed normal meiosis. The X2 test showed that the mutation is controlled by a single recessive gene. The protein content was higher in the mutant while amino acids and trypsin inhibitor activity were more are less similar to the coritrol.
