Abstract: An hybridization programme was conducted at Department of Horticulture, Agricultural College and Research Institute, Madurai during kharifs 2017 and 2018 to study the per se performance of twenty four ridge gourd hybrids evolved through Line X Tester mating design with six inbreed as female parents were lines (L) L1 (Acc No. 1, PKM-1, High yield), L2 (Acc No. 2, CO-1, High yield), L3 (Acc No. 12, Virdhunagar Local, Earliness), L4 (Acc No. 19, Seranmadevi local, More no. of fruits/plant), L5 (Acc No. 21, Arka Sujath, High yield), L6 (Acc No. 22, Arka Sumeet, High yield) and four inbreds as male parents were tester (T), T1 (Acc No. 7, Periyakottai local, High length of fruits), T2 (Acc No. 16, Alathur local, Fruit diameter), T3 (Acc No. 17, Kannapatti Local, Node to first female flower appear), T4, (Acc No. 20, Srirampuram Local, More Female: Male ratio) used in the crossing programme. The parents were raised in the filed during Kharif 2017 for hybridization. The per se performance of parents and hybrids showed that the parents L3 (2.97kg/vine) and L4 (2.58kg/vine) were high yielding. Among the twenty four crosses, three cross combinations viz., L3 x T2 (4.75kg/vine), L3 x T1 (4.45kg/vine), L5 x T2 (4.25kg/vine) recorded higher values for yield per vine. The high fruit weight was recorded in L3 X T1 (259g), L3XT2 (270g), L5XT2 (295g). The number of fruits per vine was high in L3XT2 (17.60), L3XT1 (17.20) and L2XT4 (16.40). The yield per hectare was high in L3XT2 (19.01t), L3XT1 (17.82t) and L5XT2 (16.99t). The high total soluble solids was observed in L2XT2 (5.00brix) and L4 XT4. The highest crude fiber content was estimated in L3XT1 (0.58mg/100g), L4XT4 (0.50mg/100g) and L3 XT2 (0.56mg).
