Abstract:
The present investigation was carried out to estimate the extent of variability, correlation, path and genetic divergence for yield and quality related traits in pumpkin. The significant differences among genotypes were revealed by analysis of variance for all the 28 characters, indicating the presence of considerable genetic variability for the traits studied. The high genotypic coefficient of variation (GCV) and high heritability coupled with high genetic advance as per cent of mean was observed for 18 out of 28 characters indicating that sufficient variability existed in the experimental material. The correlation coefficient revealed a significant and positive association of 14 characters with fruit yield per vine (kg). Path analysis based on genotypic correlation showed positive and direct effects for 17 characters indicating the importance for these characters to impose selection pressure for improvement in pumpkin yield. Based on per se performance genotypes, GPPK 115, GPPK 18, GPPK 105, GPPK 95, GPPK 143 and AP 1 were identified as elite genotypes and could be used in the future breeding programme for improving yield in pumpkin.
