Character association and path coefficient analysis of bitter gourd (Momordica charantia L.) genotypes

Author(s): Nidhi Tyagi, VB Singh and Praveen Kumar Maurya
Abstract: Estimates of correlation and path coefficients can help the mutual relationship between various plant characters and determines component characters on which selection can be based or improvement in yield. It might be easier to increase yield by increasing the smallest yield components on an otherwise good cultivar. Thirty one genotypes of bitter gourd were evaluated for yield contributing characters to observe their associations and direct and indirect effect on fruit yield. The study revealed that in most of cases the genotypic correlation coefficient was higher than the respective phenotypic correlation coefficients. This indicated that the suppressive effect of the environment modified the phenotypic expression of these characters by reducing phenotypic correlation values. Fruit yield per plant (kg) showed significant positive association with average fruit weight (g) at genotypic and phenotypic level. Path analysis revealed that average fruit weight (g) and number of fruits per plant had the greatest direct effect on yield both at phenotypic and genotypic level suggesting their importance while imposing selection for correlation of yield in bitter gourd.
