Correlation and path coefficient analysis for some morphological and biochemical constituents of jackfruit genotypes.

摘要

A study was conducted to assess the correlation among fruit weight and its components and path coefficient analysis to provide adequate genetic background for direct and indirect effect of various characters on fruit weight of jackfruit. The results revealed that genotypic and phenotypic correlation were positively significant between fruit weight of edible part (0.980 and 0.977), fruit and rind weight (0.976 and 0.971), and number of stones and flakes (0.999 and 0.999). The path coefficient analysis indicated that weight of edible part had positive direct effect on fruit weight both at genotypic (0.459) and phenotypic (0.451) levels. Hence, at the time of selection of jackfruit genotypes, one has to put emphasis on the characters like weight of edible part, rind weight, flake and stone numbers.
