Eighteen hybrids generated from crossing six basmati lines with three tester parents were studied for combining ability for grain yield and its component characters. Additive gene action was predominant for flag leaf area, panicle length, grain weight panicle^-1 and grain yield plant^-1 while days to flowering, PBT plant^-1, grains panicle^-1 exhibited preponderance of non-additive gene action. Kasturi, Basmati 5853 and Haryana Basmati 1 among the lines and Pant Dhan 11 among the testers emerged as good general combiner for various traits. Basmati C 622 x TN 1, Basmati. 5853 x Pant Dhan 11and Pusa Basmati 1 x T N 1 crosses were emerged as most promising.
