Correlation and path coefficient analysis studies in Sapota [Manilkara achras (Mill.) Fosberg] genotypes

Abstract

Assessment of variability and understanding of traits relationship in sapota are vital pre-requisite for formulating an effective breeding programme. A study was conducted to analyze the correlation and path coefficient for fruit yield and its yield attributing traits using 14 genotypes of sapota at Fruit Research Station, Navsari Agricultural University, Navsari (Gujarat). Fruit yield per plant showed highly significant and positive correlation with canopy spread East – West, number of leaves per shoot, number of flowers per shoot, L : B ratio, average fruit weight, number of fruits per tree, total soluble solids and chlorophyll content at both genotypic and phenotypic levels. Path coefficient analysis revealed that average fruit weight and number of fruits per tree had the highest direct effect on seed yield. This suggests that the two attributes have a strong influence on fruit yield. Hence, average fruit weight and number of fruits per tree are the main determiners of seed yield per plant in the studied variety.
