Resistance to race 1 of Fusarium wilt of chickpea (Cicer arietinum L.): Genetics and mapping of resistance genes in an intraspecific cross

Published on

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
resistancewas 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.
