The present investigation was conducted to determine heterosis in 6 lines and 4 tester crosses of bitter gourd, where the six lines used were MC-84 (L1), S-17 (L2), JMC-21 (L3), NDBT-15(L4), VRBT-94 (L5) and Gy-1 (L6) and the four testers were VRBT-6-9 (T1), JMC-22 (T2), VRBT-89 (T3) and MC-56 (T4). Most of the crosses failed to manifest significant heterosis for many of the horticultural traits but traits, like vine length and fruit length showed positive significant heterosis, while, days to first appearance of female flower manifested negative significant heterosis in several crosses. Two crosses, namely, MC-84 x VRBT-6-9 and MC-84 x JMC-22 were identified to have potential in terms of yield, whereas two more crosses viz., S-17 x VRBT-6-9 and S-17 x JMC-22 were found superior in terms of powdery mildew resistance.Keywords

The variance analysis for 17 plant characters showed significant differences. Maximum vine length was recorded in IC-85635A. Significantly higher number of primary branches per vine and internodal length were observed in IC-85639. Maximum number of nodes was observed in JMC-4. Significantly minimum number of days for first appearance of male flower and maximum fruit length, fruit width, yield per vine, yield per plot, yield/ha were recorded in MC-84. Highest number of fruits per vine was recorded in GY-I and minimum powdery mildew infestation was observed in JMC-22.Keywords
