Trait Association and Path Coefficient analysis of Burmese Grape (Baccaurea sapida Muell. Arg.)

Abstract

This experiment was conducted to select the suitable yield and yield contributing characters of twenty-five burmese grape genotypes by correlation coefficient and path coefficient analysis. Correlation coefficient analysis revealed that fruits yield per plant (kg.) had a highly significant positive correlation with base girth (0.68), canopy spreading at east-west direction (0.65), Canopy spreading at north-south direction (0.54) and plant height (0.52). Fruits yield per plant (kg.)  showed a significant positive correlation with the weight of seeds per fruit (0.5) and the number of seeds per fruit (0.42) which indicated that yield could be increased by the emphasis upon these traits. The number of fruits per plant (1.067) showed the highest positive direct effect on fruits yield per plant and the considerable positive direct effect observed in fruit length (0.715) followed by plant height (0.566), base girth (0.341), edible percentage (0.329) and canopy spreading at north-south direction (0.275) and most other traits linked upon fruit yield per tree have indirect contribution within these traits. Therefore, it might be assumed that these traits could be considered as the most significant yield contributing traits in Burmese grape to develop improved quality and high yielding burmese grape variety.
