Abstract:
In wild habitats, pod dehiscence is a critical strategy for seed dispersal; however, in cultivated crops it is one of the major source of yield loss. Therefore indehiscence of pods was likely to be one of the first traits strongly selected in crop domestication. The forty genotypes studied in present investigation showed quite significant differences among themselves for pod shattering tolerance. The average percentage of pod breakage was observed 34 per cent. In terms of pod shattering tolerance, among the 40 genotypes, MACS-1701 (2%), MACS-NRC-1647 (4%), RVSM-2011-10 (8%), AMS-100-39 (10%), DSB-33, MACS-450, KDS-1096 (12%), KDS-344, PS-1670, and KDS-1144 (14%), were found to be highly to moderately tolerant. The strongest correlation at the genotypic and phenotypic level was found between number of pods per plant and seed yield per plant, which was followed by the days to 50 percent flowering and days to maturity. While pod shattering percentage showed positive but non-significant association with seed yield.
