Abstract

Fusarium wilt causes 10% annual loss in India. Studies on F1, F2, F3 and F10 recombinant inbred line populations (RILs) of chickpea cultivars ICCV2 (resistant) and JG 62 (susceptible) against Fusarium race 1 suggested that resistance in this cross is governed by two recessive genes h1 and h2. The linkage map constructed using 126 F10 RILs comprised of 49 molecular and 7 phenotypic markers with nine linkage groups. The h1 gene governing Fusarium resistance was linked to RMMFP1 and TA59 markers. TA59 marker assigned this locus to cluster of Fusarium resistance genes on linkage group 2 of the interspecific genetic map.
