Screening of chickpea genotypes against wilt/root rot complex under different environments

Wilt/root rot complex caused by Fusarium oxysporum f. sp. ciceri/Rhizoctonia bataticola is most destructive and widely distributed disease in India and causes severe losses in yield. Therefore, the present study was undertaken to screen 25 genotypes of chickpea (Cicer arietinum L.) including three checks under natural epiphytotic conditions for their reaction against wilt/root rot complex diseases in two different environments. In Env. I, highest yielding genotype ICCV-96904 was found resistant and superior over Himachal Chana-1 (check) which was moderately susceptible. Other check i. e. HPG-17 was showing resistance, whereas Himachal Chana-2 was moderately susceptible in the same environment. In Env. II, highest yielding genotypes viz., L-HR-5 and L-113 were found moderately resistant over HPG-17 (check) which was showing 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. Env. I was identified as representative environment as compared to Env. II.
