Abstract

Studies were initiated to estimate the heterosis, heterobeltiosis and standard heterosis in 35 red grain sorghum hybrids under rainfed condition for eigh thiometrical characters. Maximum heterotic values for grain yield was recorded by ICSA 70 x Paiyur 2. The hybrid AKMS 14 A x Paiyur 2 recorded higher straw yield per plant. The hybrid involving the parents ICSA 70, AKMS 14 A and Paiyur 2 recorded more desirable performances for most of the characters studied.
