ABSTRACT

High GCV and PCV values were observed for plant height in the crosses viz., DRG-102 X
TCGS-150, for number of secondary branches in K-3 X TCGS-150, K-3 X ICGV-88083, ICGV-
91173 X TCGS-150, ICGV-91173 X ICGV-88083 and DRG-102 X TCGS-150, number of mature
pods in K-3 X TCGS-150, K03 X ICGV-88083, ICGV-91173 X TCGS-150, ICGV-91173 X ICGV-
88083 and DRG-102 X ICGV-88083, , pod yield per plant in ICGV-91173 X ICGV-88083 and DRG-
102 X TCGs-150, kernel yield per plant in K-3 X TCGS-150, K-3 X ICGV-88083, ICGV-91173 X
TCGs-150, ICTGV-91173 X ICGV-88083 and DRG-102 X TCGS-150. All the crosses showed high
heritability along with high GAM for plant height, number of secondary branches per plant, number
of mature pods per plant, number of immature pods per plant, kernel yield per plant and harvest
index. Pod yield showed significant positive association with days to maturity (0.268)), number of
primary branches per plant (0.239), number of mature pods per plant (0.889), shelling percentage
(0.252), kernel yield per plant (0.962), pod length (0.667), pod width (0.428) and harvest index
(0.658). So these characters have considered as selection indices for the improvement of pod yield.
