A line x tester analysis using 4 pistillate lines and 8 pollen parents, was carried out to study the heterosis and combining ability for yield and its attributes. The crosses exhibited 13.30 to 88.57% heterosis over better parent for yield 38.89 to 59.86% for spike length, 31.85-97.69% for number of capsules per plant and 27.27 to 9.26% for 100 seed weight. The hybrids VP-1 X JI-35 and SKP-4 XJI-35 are of commercial value. The female SKP-4 was good general combiner for 100 seed weight, SKP-3 for length and effective length of main spike and number of capsules per main spike and VP-1 for effective branches. Among the males JI-35 was the best general combiner for yield and important yield components. The parents having high per se performance were also good general combiners for the respective traits
