Botrytis grey mould (BGM) is a fungal disease of chickpea and can infect plants at any stage of development. In order to develop the resistant varieties, it is a necessary to understand the pattern of inheritance of its resistance and hence experiments were conducted during rabi 2014-17 at field area of GBPUAT, Pantnagar.
The six different generations of three crosses i.e., DKG 876 × GNG1581, DKG 876 × H 208 and DKG 876 × DCP 92-3 were used as experimental material. All six generations were sown in compact family block design and data obtained from field disease screening were subjected to chi-square analysis.
The results revealed that resistance to BGM was dominant over susceptibility. The inheritance of resistance against BGM showed monogenic dominant resistance in ratio of 3 (resistant):1 (susceptible). The results of present study showed the presence of a major gene in governing resistance to BGM in chickpea.
