Abstract

Summary Growth analysis was conducted under rainfed and irrigated field conditions with a bajra hybrid-1 (Hb-1) and its parents, Bil 3B (male) and Tift 23B (female). Hybrid-1 had higher total dry weight and growth rate than either of the parents at flag leaf stage. The heterosis in vegetative phase was closely associated with leaf area during early growth period. The tiller number varied on Titt 23B > Hb-1 > Bil 3B: The maximum tiller number was reached at flag-leaf stage in three varieties.
