Stability and adaptability estimation of the investigated trait(s) is a common procedure in most of maize breeding programmes. It is usually applied to F1 progeny but not to inbreds. This paper deals with stability and adaptability estimation of grain yield for lines and testers within its F1 hybrids. For lines and testers, general (GCA) and specific (SCA) combining abilities for grain yield were also estimated. The experiments consisted of twenty-one experimental maize hybrids obtained by line×tester mating design. Two year investigation was performed in random block design in four replications at sixteen environments. Estimated means and parameters describing stability and adaptability - regression coefficient (bi), deviations mean square (sdi) and ecovalence (Wi) detected Os84-28 line and Os84-28 tester, both as most yielded and widest adapted inbreds. Combining ability estimation showed highly significant effects of lines, testers and their respective interactions with environment for grain yield. Os84-28×Os3-48 combination had on average the highest grain yield but was not the most stable and the widest adapted genotype. It suggests that there is no strong relationship between level and stability of grain yield for parental lines and its F1 progeny. |
