Abstract

The cross Kadiri -3 x TCGS-150 recorded highest pod yield of 14.2 g with highest GCV and
PCV. All the crosses showed high heritability values ranging from 66.2 % (ICGV-91173 x ICGV-
88083) to 93.8 % (DRG-102 x ICGV-88083) and also high GAM for pod yields. High heritability
along with high GAM indicates the role of additive gene action hence, directed mass selection
procedure can be used to improve pod yield. Late leaf spot incidence was least in the crosses DRG-
102 x TCGS-150 followed by DRG -102 x ICGV-88083 and appear to be the best crosses for genetic
enhancement for foliar disease resistance. The cross DRG 102 x TCGS-150 exhibited segregants
with the least foliage damage due to Spodoptera litura as seen from lower mean damage which was followed by DRG 102 x ICGV- 88083 and ICGV- 91173 x TCGS- 150
