Diallel Analysis of Combining Ability for Yield and Yield Contributing Traits over the Environments in Maize (Zea mays L.)
Journal Title: International Journal of Current Microbiology and Applied Sciences (IJCMAS) - Year 2017, Vol 6, Issue 10
Abstract
Present study was conducted with 10 parents, their 45 hybrids along with 4 checks viz., Pratap QPM Hybrid-1, Vivek QPM-9, HQPM-1 and HQPM-5 to estimate GCA and SCA of parents and crosses respectively in diallel mating design (excluding reciprocal crosses) in two environments (Kharif 2014 and Rabi 2014-15) at the Instructional farm, Rajasthan College of Agriculture, MPUAT, Udaipur. Two characters viz., grain yield per plant and harvest index exhibited high mean sum of squares due to GCA than SCA in E1 environment while, in E2 environment they exhibited high mean sum of squares due to SCA than GCA. The estimates of SCA variance were of higher magnitude than GCA variance for all the traits in both the environments. In pooled analysis mean squares due to environment, GCA, SCA, GCA x E and SCA x E were significant for all the three characters except GCA x E and SCA x E for number of grain rows per ear. The estimates of GCA effects for grain yield per plant revealed that only three inbred lines viz., EIQ–106, EIQ–109 and EIQ–112 in E1 and only two inbreds; EIQ–112 and EIQ–109 in E2 showed positive significant GCA effects. The estimates of positive significant SCA effects for grain yield per plant were depicted by 20 and 17 hybrids in E1 and E2 environments respectively. The estimates of GCA effects revealed that good general combiner inbred lines for grain yield per plant were EIQ–112, EIQ–109 and EIQ–106 in E1 environment while, EIQ–109 and EIQ–112 in E2 environment. On the basis of mean and SCA effects out of total 45 hybrids, five hybrids which exhibited higher mean and significant positive SCA effects for grain yield per plant were EIQ–110 x EIQ–112, EIQ–107 x EIQ–109, EIQ–109 x EIQ–111, EIQ–105 x EIQ–112 and EIQ–105 x EIQ–114 in E1 environment while hybrids EIQ–110 x EIQ–112, EIQ–105 x EIQ–112, EIQ–109 x EIQ–111, EIQ–107 x EIQ–109, EIQ–105 x EIQ–113 in E2 environment. Among these the crosses EIQ–110 x EIQ–112, EIQ–107 x EIQ–109, EIQ–109 x EIQ–111, EIQ–105 x EIQ–112 were better performer in both the environment.
