Studies on genetic variability, correlation and path analysis in chilli (Capsicum annuum L.).

摘要

Fifty-five accessions of chilli (Capsicum annuum) were evaluated for 12 quantitative characters including yield. High heritability coupled with high genetic advance was noticed through number of fruits per plant, number of seeds per fruit, seed weight, fruit length and stalk length, suggesting that these characters could be considered reliable indices for selection. The phenotypic and genotypic coefficients of variation were highest for yield per plant, number of fruits per plant and seed weight, indicating the highest level of variability for these traits and also indicated ample scope for effective improvement through selection. Correlation studies revealed that fruit yield per plant was significantly and positively associated with all yield attributes, except for stalk weight. High positive direct effect of yield attributing characters such as fruit length, stalk weight and fruit weight resulted in significant correlation with yield. Number of fruits per plant and average fruit weight also contributed indirectly through all characters, which made the correlation significant.
