COMBINING ABILITY ASSESSMENT IN TOMATO (SOLANUM LYCOPERSICUM L.) FOR GROWTH AND YIELD

The current study conducted Vegetable Research Farm, Dr. RPCAU, Pusa attempted to determine the general and specific combining ability variances as their effects for various quantitative characteristics in tomato.Line Tester analysis including ten lines and three testers illustrated the preponderance SCA over GCA for all the characteristics studied.Combining ability effects (GCA & SCA) were estimated using thirteen parents consisting their thirty hybrids developed through Line Tester method.The results indicated that the lines, Kashi Hemant was found to be good general combiner with high per se performance may be used the best parents a donor to enhance the plant height, number of flowers cluster - 1 , polar as well as equatorial diameter of fruit, average fruit weight, acidity of the fruit and fruit yield plant -1 .In case of tester, Bhilai was found to be a good general combiner and high per se performance for traits like plant height, number of flowers cluster -1 , acidity of the fruit and fruit yield plant -1 .EC 177371 PKM-1 best hybrid to enhance the number of fruits cluster -1 , polar as well as equatorial diameter of fruit, average fruit weight and fruit yield plant -1 and plant height, number of primary branches plant -1 , number of fruits cluster -1 , TSS content of fruit S-12 PDT-3-1 were show highest SCA effects as well as high per se performance.
