Combining ability analysis for yield and yield contributing traits in chickpea (Cicer arietinum L.)
Author(s): Dalbeer, Shiva Nath and Kavita
Abstract: The experimental materials comprised of ten diverse lines of chickpea with six broad genetic base testers were crossed in line x tester fashion and evaluated for 11 quantitative characters in timely (E1) and late sown (E2) environments. Analysis of variances for combining ability revealed that variances due to lines x testers showed highly significant differences for all the characters except for days to 50% flowering in both the environments, whereas variance due to lines was also highly significant for most of the characters studied for days to 50 per cent flowering. Variances due to testers were found non significant for all the characters in both the environments. The parental lines ICCV 10 and Phule G 5 and and among testers KAK 2 with high GCA effects were identified as superior donors for seed yield per plant in both the environments. The crosses BG 362 X ICCV 07112, Phule G 5 X IPC 97-72, BG 1003 X KAK 2, ICCV 10 X ICCV 97 in timely sown and BG 362 X ICCV 07112, ICC 14364 X KAK 2, PANT G 186 X KAK 2, ICCV 10 X ICCV 97 in late sown environment showed significant & positive SCA effects for seed yield per plant as well as some other yield components.
