Six wheat genotypes (4 hexaploid and 2 tetraploid) against plant height, days to heading, days to anthesis, days to maturity, grain filling period, grains per spike and 1000 grain weight characters were studiedfor combining ability and heterosis through 6 × 6 half diallel fashion. This experiment was conducted at Regional Agricultural Research Institute Bahawalpur during 2016-17. Results of mean square of general combing ability (GCA) and specific combing ability (SCA) was found significant for all studied characters except forplant height and grains per spike against SCA. Ratio of GCA/SCA showed the involvement of additive gene action in the inheritance of all under studied traits. Durum-1 was found best parent among all other parents against 1000 grain weight and days to heading. Miraj-08 was good general combiner as it reflected maximum grain yield per plant. Best specific combing ability and heterosis was exhibited by cross combination Ass-11× Chakwal-50, Glaxy-13 × Chakwal-50 and Chakwal-50 × Miraj-08 against plant height, grain per spike and yield character. Results indicated that selection of best general combiner would be helpful in increasing yield through hybridization and superior hybrids may develop by the selection of superior best specific combiners.
