Heterosis in Indian mustard (Brassica juncea L. Czern & Cosson)

Jay Lal Mahto, Z.A. Haider

Abstract


An investigation involving 45 genotypes (nine parents and their diallels, excluding reciprocals) to identify the high heterotic crosses in Brassica juncea L. was undertaken during the winter seasons of 1995-96 and 1996-97 at Ranchi. The cross combinations RH 843 x RH 851 and PR 18 x BR 40 showed high relative heterosis and heterobeltiosis, respectively, for most characters. Overall, crosses PR 18 x BR 40, PR 830 x RH 851 and RH 843 x RH 851 were superior to others in heterotic effects.
