Character association and yield components studies in Ivy gourd (Coccinia grandis L. Vogt.)

Abstract

Estimates of phenotypic and genotypic correlations for the various combinations of yield and its components are presented. Eighteen genotype of Ivy gourd were assessed for correlation analysis for yield and its attributes. The differences among genotypes were statistically significant for all the thirteen quantitative characters. Correlation studies among the fruits indicated that number of fruits/plant had high significant positive association with fruit yield at both phenotypic and genotypic levels followed by stem girth, number of fruits/plant, number of primary branches, leaf area, vine length, days of first harvesting and fruit weight had high to moderate direct effect on yield which indicated their better prospects for further crop improvement.
