Abstract: An experiment was conducted at college of horticulture, Venkataramannagudem, Dr. YSR Horticultural University, Andhra Pradesh during Rabi season 2017-18 to find out suitable ridge gourd genotype for earliness, yield, growth and biochemical attributes under coastal Andhra Pradesh region, 42 genotypes were evaluated for characters. Analysis of variance revealed that mean sum of squares due to genotypes was highly significant for all characters. Among 42 genotypes, the genotype Rg-92 was noted for earliness for days to first male flower appearance (32.60), the genotype Yerrabalem Local for days to first female flower appearance (38.60), the genotype RV-6 for node at which first female flower appeared (6.70), the genotype IC-523892 for days to 50 per cent flowering (45.60), the genotype ERG-4 for days to first harvest (50.00), the genotype Satputia for sex ratio (3.45) and maximum days to final harvest (96.30) in Rg-91 genotype. The cultivar Arka Sujath was noted for maximum vine length at 45 DAS (2.40), vine length at 90 DAS (4.60), number of primary branches appearance at 45 DAS (3.75), cultivar Arka Sumeeth for number of primary branches appearance at 90 DAS (6.75). Maximum number of fruits per plant (14.17), fruit yield per plant (4.26), fruit yield per plant (4.26), fruit yield per hectare (26.38), average fruit weight (306.21), rind thickness ( 5.67) in the genotype Chikkamagaluru Local, fruit diameter (6.08), flesh thickness (5.17) in the genotype Rg-112 and maximum fruit length for genotype Jaipur Long (32.52). Regarding quality parameters, maximum total soluble solids (5.55), moisture content (96.67) was recorded in genotype Arka Sumeeth, fiber content (2.70) in Kolar Local and Vitamin C (4.58) in Rg-93 and Rg-99. Thus identification of promising genotypes as a commercial crop for the area with high yield and quality fruits would help the farmers in its adoption and improving their economic status.
