COMBINING ABILITY AND GENE ACTION FOR TANNIN CONTENT IN SORGHUM GRAIN

Abstract

Estimates of components of variance and combining ability were estimated for grain tannin in 7 x 7 diallel sat of sorghum. Additive and non-additive gene actions were both found to be important while the former had got vital role in determining the tannin in sorghum grain. IS 2261 and IS 9225 were the best combiners. The high sca effects in poor x poor and poor x high indicated the non allelic interations for the inheritance of tannin content in sorghum grain.
