STUDY ON THE PERFORMANCE OF MAIZE (ZEA MAIZE L.) HYBRIDS FOR YIELD AND QUALITY AT KANPUR AGROCLIMATIC CONDITION.

Abstract

In the present investigation, heterosis, combining ability effects and yield related parameters were studied for various traits to developed and identify suitable and stable single cross hybrids. The analysis of variance for experimental design revealed the presence of significant amount of variability for most of the characters in the experiment. This suggested that the parental lines selected were quite variable for most of the characters under study. Further, the analysis of variance revealed that genotypes showed significance for all the traits indicating the presence of sufficient variability in the experiment/ study material. Presence of sufficient amount of variability encourages for screening of the genotypes for yield. The per se performance of days to 50% tasselling, days to 50 % silking and anthesis silking interval revealed that the hybrids IL7 X IL8, IL1 X IL11, IL9 X IL12, IL9 X IL12 and IL5 X IL7 showed minimum value. On the basis of mean data, we can identify the early maturity hybrids. Mean data revealed that yield and yield contributing traits revealed that the hybrids IL1 X IL8, IL7 X IL8, IL9 X IL10 and IL1 X IL3 showed maximum value. On the basis of mean data, we can identify the high yielding genotypes hybrids.
