Correlation and Path Analysis in Multicut Fodder Sorghum

Genotypic correlation coefficient and path coefficient analysis was carried out in 109 genotypes of multicut fodder sorghum between fourteen fodder yields and yield related characters for each cut and subjected to pooled analysis. The result showed that all the characters except hydrocyanic acid, total soluble solids and crude protein had positive significant association with green fodder yield per plant. Among these traits dry fodder yield exhibited high correlation (0.953) coefficient with green fodder yield per plant followed by leaf length, plant height and number of leaves. Plant height exerted the highest direct effect on green fodder yield followed by leaf length and breadth and leaf stem ratio. Hence, selection for any of these traits might result in simultaneous improvement in the yield. The results of correlation and path analysis indicated that due importance should be given for plant height because of its significant correlation and high direct effect, apart from its high indirect effect through dry fodder yield.
