The present study was undertaken to screen twenty five genotypes of chickpea under natural epiphytotic conditions for their reaction against wilt (Fusarium oxysporum f. sp. Ciceri)/root rot (Rhizoctonia bataticola) disease complex in two different environments. In normal sown crop (Env I), four genotypes viz., HPG-17 (check), Line-306, ICCV-182 and ICCV-96904; in late sown (Env. II) three genotypes viz., ICCV-95509, Himachal Chana-1 (check) and HPG-17 (check) were found resistant. In Env. I, highest yielding genotype ICCV-96904 was found resistant and superior over Himachal Chana-1 (check) which was moderately susceptible. HPG-17 was showed resistance, whereas Himachal Chana-2 was moderately susceptible in the same environment. In Env. II, highest yielding genotypes viz., Line-HR-5 and Line-113 were found moderately resistant over HPG-17 (check) which was sowing complete resistance. The reduction in seed yield per plant in late sown environment was observed to be 33.54% as disease incidence was more in this environment. Four genotypes in Env. I viz., HPG-17, Line-306, ICCV-182 and ICCV-96904 and three in Env. II viz., ICCV-95509, Himachal Chana-1 and HPG-17 were found resistant against wilt/root rot complex and thus can be used as donor parents in resistance breeding programme. Eight genotypes each viz., Line-334, Line-HR-1, BGD-112, DKG-7-4, Line-HR-5, Line-221, ICCV-96910 and Line-294 in Env. I and ICCV-182, Line-306, Line-HR-1, Line-333, DKG-7-4, Line-113, Line-HR-5 and ICCV-96910 in Env. II were showing moderately resistance for the disease symptoms. Overall, it can be concluded that three genotypes viz., ICCV-96904 (resistant) in Env. I, Line-HR-5 and Line-113 (moderately resistant) in Env. II were observed as best genotypes.
