Abstract

One hundred and twenty rice bean genotypes were assessed for 11 agronomic traits against three different elite varieties RBL-6, RBL-35, RBL-50 in Augmented Design during the Kharif 2005. There was no significant difference among the blocks and as well as checks. The variety RBL-50 among the checks registered highest seed yield (q/ha). The nineteen test entries viz. BRB10, LRB115, BRB06, BRB15, LRB109, BRB19, BRB14, LRB081, BRB08, BRB01, BRB03, LRB110, LRB118, BRB09, BRB07, BRB05, LRB043, LRB020, LRB075-1 showed higher seed yield (q/ha) than the best check variety RBL-50 (9.21 q/ha).

120 Rice bean genotypes and four released varieties were evaluated for genetic variation and correlation.

The results of this study indicate that these rice bean genotypes can be used for future breeding programs to enhance the seed yield of Rice bean in India.
