Abstract 

Botrytis grey mould (BGM), caused by the fungus Botrytis cinerea Pers. ex Fr., is an important disease of chickpea causing economic losses across the world in chickpea-growing regions. There are no available resistance sources in cultivated chickpea against this disease. Cicer echinospermum and C. reticulatum, the only two compatible annual wild species, have been reported to have resistance to BGM. Hence, interspecific populations were developed with susceptible cultivars as female parents and C. echinospermum accession IG 73 074 and C. reticulatum accession IG 72 937 as the pollen donors to transfer and assess the nature of genetic control for BGM. Screening the progeny indicated that resistance to BGM was controlled by a single additive gene/allele (bgmr1 cr and bgmr1 ce), which can be introgressed through a backcross breeding programme.
