Abstract

In a field experiment conducted at the International Center for Agricultural Research in the Dry Areas in Syria during 1982–83, 1983–84, and 1985–86 crop years, disease progress of Ascochyta blight was studied in chickpea cultivars ILC 464, ILC 482, and ILC 3279. On the basis of apparent infection rate (r), ILC 482 (r = 0.16–0.29) and ILC 3279 (r = 0.03–0.23) were identified as cultivars with rate-reducing resistance in comparison with the susceptible cultivar ILC 464 (r = 0.24–0.68). Average grain yield for three seasons was nearly 1,800 kg·ha–1 for ILC 482 and ILC 3279 but only 100 kg for ILC 464.
