摘要

Genotypic correlations and path-coefficients were determined for nine yield-related agronomic traits using 10 accessions of scarlet eggplant. There were significant (P < 0.05) differences among the 10 accessions for all traits and differences were largely due to genetic effects. There was no significant positive correlation between any trait and fruit yield, but number of days to flowering, plant height at flowering and number of days to fruit maturity were significantly (P < 0.05) and negatively correlated with fruit yield. Path-coefficient analyses showed that number of fruits per plant had the highest direct effect on fruit yield, followed by fruit diameter. Low correlation between number of fruits per plant and fruit yield was due to large negative indirect effects via fruit diameter, fruit length and fruit weight. Despite the significant negative correlation with fruit yield, number of days to flowering had a positive direct path towards fruit yield. The negative correlation resulted from large negative indirect effects via days to fruit maturity, fruit diameter, fruit length and fruit weight. Selection for high yield should be exploited through correlated response of fruits per plant, fruit diameter and days to flowering, which were the major determinants of fruit yield.
