COMBINING ABILITY ANALYSIS, IS BEING WIDELY UTILIZED BY PLANT BREEDERS, FOR BEST COMBINATION ANALYSIS IN DIFFERENT CROPS. TOMATO, AS GROWN IN ALL PARTS OF THE WORLD, NEEDS CONTINUOUS SELECTION FOR VARYING ENVIRONMENTS AND CHANGING CLIMATIC CONDITIONS. ALSO, THE GERM PLASM CONSERVATION IS MAIN OBJECTIVE FOR UTILIZING IN BREEDING PROGRAMS. HERE COMBINING ABILITY OF DIFFERENT PARENTS HAS BEEN EXPLORED FOR YIELD AND ENVIRONMENTAL STABILITY OF HYBRIDS FOR SUSTAINABLE CROP PRODUCTION. DIFFERENT TRAITS, INFLUENCING YIELD AND ENVIRONMENTAL STABILITY HAS BEEN CHECKED USING GCA AND SCA ANALYSIS.
