Abstract
Field investigation with twenty five genotypes of bottle gourd was undertaken to elicit information on evaluation for growth, earliness, yield, quality, seed parameters and pest and disease incidence at Department of Vegetable Science, Kittur Rani Channamma College of Horticulture, Arabhavi during kharif, 2009-10.
Analysis of variance revealed significant (p=0.05) differences among treatments for 24 growth, earliness, yield, quality and seed parameters. The genotype Sarika was found to possess maximum number of primary branches. While, Anand Bottlegourd-1 recorded maximum vine length and Thar Samridhi was noted for highest number of leaves and thicker flesh. The genotype NBBL-12 was noted for earliness to flowering and fruiting, while, the genotype Gaja was found to be promising for lower sex ratio (male to female), more number of fruits per vine, fruit yield per hectare and seed yield per hectare.
Performance studies revealed that the genotypes Gaja, NS-421, NBBL-12, Sharada, INDAM-204, NS-443, Super Dhana, Arka Bahar and Krushi Sampada were found promising for fruit yield and Anand, Gaja, Gutkha and NS-443 for seed yield. The genotypes Gutkha, Sarika and Kaveri were found to show resistant reaction against downy mildew. Elina was found to be resistant to fruit fly while US-15, Sharada, Arka Bahar, Champion and NBBL-52 were found to show least incidence.
Correlation studies revealed significant and positive association of fruit yield with vine length, number of fruits per vine, fruit yield per hectare, seed yield per fruit, seed yield per vine and seed yield per hectare. Whereas, seed yield was significantly and positively correlated with vine length, T.S.S., number of fruits per vine, average fruit weight, fruit yield per vine, fruit yield per hectare, 100 seed weight and seed yield per hectare, suggesting that possibility of simultaneous selection for these traits.
