Genetics of alternaria leaf blight resistance in Indian mustard [Brassica Juncea (L.) Czern & Coss.]

  • R. K. Chaurasia Ram Bhajan

Abstract

Inheritance of Alternaria leaf blight disease in Indian mustard (Brassica juncea L. Czern & Coss) was carried-out using generation mean analysis. Results based on generation mean analysis of per cent disease index (PDI) showed significant estimates of additive [d] and dominance [h] effects as well as all the three types of epistasis in all the three crosses. The opposite signs of [h] and [l] indicated that duplicate epistasis was operative in the inheritance of Alternaria leaf blight in the material studied.
