| Abstract: | Correlation and path analysis of 14 agronomic traits of bitter gourd were studied. The results of correlation analysis revealed that very significant positive correlation were found between the first ten days yield,lasting harvest time,number of fruit per plant and yield respectively. While,very significant negative correlation were found between days of first female flowering,days of flowering,node of first female flower,node of first fruit and yield respectively. The results on path analysis showed that the yield was affected mostly by three agronomic traits,the number of fruits,lasting harvest time and average fruit weight by turn. |
