Abstract: Ten combining ability and the genetic effects of main agronomic characters of new released male steral lines A2F4A,A1356A and three commercial A lines as well as their hybrids from nine R lines was analysed.The results indicated that the combining variance was significant in plant height,panicle length,days to 50% flowering,panicle weight,grain weight per panicle,number of grains per panicle,1000 grain weight.Genetic analysis showed that additive effect was prominent in the character inheritance.GCA effects of A2F4 were significantly higher than other male sterile lines in all 8 characters.GCA was significantly higher than other restorer lines effects of R line 8643 on the plant heitht,grain weight per ear and days to 50% flowering.

Key words: Sorghum, Combining ability, A2F4, A1356
