Identification of Characters Correlated with Tuber Yield in Guinea White Yam (Dioscorea rotundata Poir)

Abstract

This study provides strong evidence that the yield parameters having important contributory factors to tuber yield should be considered in breeding and selection for higher tuber yield in guinea white yam. However, the negative correlation observed between fresh tuber yield and number of leaves per plant shows that number of leaves though an important morphological character is not a major contributory factor to yield in guinea white yam.
