Abstract:
Elephant foot yam is an important tuber crop of the tropical and sub-tropical countries. The present experiment was conducted to know the association of various characters with corm yield in 21 germplasm of elephant foot yam. Study of correlation between different quantitative characters provides a thought of association that would be effectively exploited to formulate selection strategies for improving yield components. Correlation coefficient studies indicated that the characters like pseudostem girth, pseudostem length, chlorophyll content and leaf canopy diameter had highly significant and positive correlation with corm weight per plant. Path analysis revealed that chlorophyll content had high positive direct effect on corm weight per plant. While, psuedostem length and calcium oxalate had moderate positive direct effect on corm weight per plant. Thus, these characters have to be given importance in selection process for improvement in corm yield.
