Recent advances in quantitative trait loci (QTL) analysis have facilitated studies on Ascochyta blight, caused by Ascochyta rabiei Pass (Lab.), resistance in chickpea (Cicer arietinum L.). Using a recombinant inbred line (RIL) population derived from an interspecific cross between C. arietinum and C. reticulatum, the same 2 QTLs conferring resistance to Ascochyta blight were identified at 2 locations by interval mapping. Genotype X environment (G x E) interaction was significant both between years at the same location and between locations. The effect of QTL-1 on linkage group 8 (LG-8) was greater than that of QTL-2 on LG-4 at Pullman while …
