The investigation was undertaken at Department of Horticulture, SHIATS, Allahabad, during the year 2014. The experiment was laid out in simple Randomized Block Design with 3 replications, 12 genotypes (6 genotypes from IIVR Varanasi and 6 local cultivators) separately. Studies showed that, significant effect on the minimum days to germination ( days), days to first appearance of male and female flower ( and days), node number at which first male and female flower appear ( and ), sex ratio (), length of main vine (), minimum days to first harvesting ( days), fruit length ( cm), fruit weight ( gm), fruit diameter ( cm), fruit yield (), . ( 0Brix) and vitamin C ( mg/100gm) was observed maximum in treatment with T6 RIGVAR-6. The treatment T6 (RIGVAR-6) was found to be the best out of 12 genotypes in terms of growth, yield, quality and economic returns. The highest B:C ratio () was found for ridge gourd, in genotypes RIGVAR-6 under the agroclimatic condition of Allahabad. | Studies on genetic variability in ridge gourd Luffa acutangula L.
