Studying Correlation in Early Maturing Maize (Zea Mays) Inbred Lines in Central Rift valley of Ethiopia

Mieso Keweti , Dagne Wegary

Abstract: This work was executed to estimate correlation among yield and yield related traits in early maturing maize inbred lines. Hence, fifteen inbred lines were crossed in a diallel mating system. Two standard checks along with one candidate variety and hybrids were evaluated in Alpha Lattice Design with two replications at Melkassa Research Center. Grain yield showed positive and highly significant correlations with plant height, ear height, ear per plant, ear length, ear diameter, number of kernels per row, number of kernels per ear and thousand kernel weights at phenotypic and genotypic levels. This suggests that grain yield could simultaneously be improved by selecting for these traits. In general, this study identified inbred lines and hybrid associations that had desirable expression of important traits. This will be useful for the selection of high yielding and early maturing hybrids for all locations.
