- Knowledge on trait association provides basic criteria for an efficient selection program. This study was undertaken to elucidate the most reliable fruit yield contributing traits in chili pepper. Measurements were made on 15 agronomic traits of 49 chili pepper families generated from a complete diallel cross of 7 parental lines. Analysis correlation revealed that fruit yield per plant had highly significant positive correlations with canopy diameter, fruit number, marketable yield, average fruit weight, and fruit length. Path coefficient analysis based on fruit yield per plant as the dependent variable indicated that positive direct effects of fruit number, marketable yield, average fruit weight, and fruit length were the main contributing traits to fruit yield per plant with the maximum effect was exhibited by fruit length. The significant correlation of canopy diameter with fruit yield per plant was mainly due to indirect effect over marketable yield. Both analyses suggested that chili pepper selection program for higher fruit yield could be based on these traits as selection criteria.
