Abstract

Correlation coefficients and path analysis were computed for grain yield with some of the yield components namely ear length, ear girth, grain number per ear and 1000 kernal weight in 10 parents and their all possible 45 direct crosses. The correlation coefficient values were highly significant for the yield attributes studied on yield and they have indicated their strong correlation with yield and their inherent capacity to influence it. The path analysis revealed that, 1000 kernel weight had the maximum direct effect on yield, where as ear length and ear girth exhibited indirect effect via 1000 kernel weight on yield. Further, grain number per ear had influenced the grain yield mainly through ear length. Among the yield attributes studied, 1000 kernel weight seems to be the most important trait influencing the vield directly as well as indirectly
