| Abstract: | The proposed genetic correlation analysis, that involves the partitioning of the overall genetic correlation into an additive and a non-additive component, has been applied to data obtained from a diallel experiment involving 12 white modified opaque-2 maize inbred lines. The correlation analysis provided an insight into possible indirect selection strategies for the improvement of inferior kernel quality traits associated with the opaque-2 gene. Direct selection for high yield and low vitreousness rating would provide an efficient selection strategy for the development of high-yielding modified opaque-2 maize hybrids with desirable endosperm traits. It was concluded that it is not necessary to conduct the density, hardness and breakability determinations. |
