Heterosis studies for growth, yield and quality parameters in ridge gourd [Luffa accutangula (Roxb.) L.]


Author(s): V Krishnamoorthy

Abstract: A field trial carried out at Department of Horticulture, Agriculture College and Research Institute, TNAU, Madurai to study the heterosis for growth, flowering, fruit and quality traits of ridge gourd. Twenty four ridge gourd hybrids, six female parents (lines), four male parents (Testers) and one commercial check were sown in the field during kharif, 2018. The highest standard heterosis value was noticed for days to first male flower in L5XT3 (29.50), days to first female flower in L5XT2 (32.99), L5XT4 (32.99), node to first male flower in L5XT3 (347.37), node to first female flower in L3XT1 (80.51), sex ratio in L3XT1 (-33.54), days to harvest in L3XT3 (-13.20), vine length in L5XT2 (-43.90), fruit length in L5XT1 (56.79), fruit girth in L5XT4, L5XT1 (25.53), fruit rind thickness in L6XT4 (75.00), L3XT2 (50.00), fruit flesh thickness in L6XT3 (-18.92), number of fruits per plant in L3XT2 (178.21), L3XT1 (149.82), yield per plant and yield per hectare in L2XT3 (279.45), L3XT2 (221.92), L3XT1 (204.79). The heterosis for quality parameters found to be high in L2XT2 and L3Xt2 (47.06 and 23.53) for total soluble solids, for dry matter content in L6XT2 (147.83), moisture content in L6XT2 (-8.67) and for total crude fiber content in L3XT1 (45.00). The L3XT1 and L3XT2 found to show significant heterosis in the desired direction for most of the traits under study and they can be exploited as desirable hybrids.
