Correlation and path coefficient analysis for yield and horticulture traits in different genotypes of Colocasia (Colocasia esculenta var. antiquorum (L.) Schott)

Author(s): Manvendra Singh and GC Yadav
Abstract: Correlation and path coefficient analysis studies conducted in forty diverse genotypes of taro with objective to know association among character viz., Days to sprouting, length of leaf (cm), width of leaf (cm), girth of plant (cm), petiole length (cm), sheath length (cm), height of Plant (cm), length of cormels(cm), girth of cormels(cm), number of cormels/plant, weight of cormels/plant(g), length of corm (cm), girth of corms (cm), weight of corms/plant (g),dry matter (%), yield/plant(g). Present study revealed that the trait yield/plant had significant and positive phenotypic and genotypic correlation with Weight of cormels per plant(g), weight of corms per plant (g), number of cormels per plant and dry matter (%). Inter relationship study revealed that for improvement of taro weight of cormels/plant (g), weight of corms/plant, girth of cormels (cm) and dry matter (%) at phenotypic level. Path coefficient analysis revealed by weight of cormels per plant followed by weight of corms per plant, length of leaf (cm), dry matter (%), girth of cormels per plant (cm), days to sprouting. exhibited greater direct effect on tuber yield p/plant (g). Therfore, therse character appear to be the most important traits for colocasia improvement programme.
