Evaluation Of Yield And Yield Components In Inbred Maize Lines I. Heterosis And Line X Tester Analysis Of Combining Ability, Şevket Meti̇n Kara

Turkish Journal of Agriculture and Forestry

In maize, three male testers and six female lines together with their 18 F_1 hybrids were evaluated to study the general and specific combining ability estimates and heterosis following line x tester approach. Analysis of variance indicated the existence of significant variation among F_1 and parents for all characteristics. Average heterosis was significant for all characteristics studied and was positive, except for days to tasseling, with the average yield of hybrids being 79.8% above that of the parents. In view of the general combining ability effects of the parents, the parental lines YUZ P709 and FR 64A were identified as …
