Abstract

Generation mean analysis in maize was performed using the progenies (F1, F2, BC1, BC2) of the cross IC- 328883 x IC-541068. Significant differences among parents and generations were observed for all the 12 traits studied. Dominance x dominance epistatic gene effects were most important in governing maturity traits and yield attributing traits whereas additive x additive type gene action was important for ear girth. Dominance gene effects were prominent for number of kernel rows per cob. Duplicate type of gene action was more frequent than complementary type. Non applicability of simple additive-dominance model revealed the importance of epistatic/inter allelic components in maize which can be exploited through heterosis breeding or recurrentselection.
