Abstract
- Sequence-tagged microsatellite site (STMS) and sequence-tagged site (STS) markers linked closely to Fusarium oxysporum f. sp. ciceris race 3 resistance gene in chickpea were identified, and linkage between three wilt resistance genes was elucidated. The resistance to race 3 in chickpea germplasm accession WR-315 was inherited as a single gene, designated foc-3, in 100 F(7) recombinant inbred lines derived from the cross of WR-315 (resistant) x C-104 (susceptible). The foc-3 gene was mapped 0.6 cM from STMS markers TA96 and TA27 and STS marker CS27A. Another STMS marker, TA194, at 14.3 cM, flanked the gene on the other side. Linkage between foc-3 and two other chickpea wilt resistance genes, foc-1 (syn. h(1)) and foc-4, was established. foc-3 was mapped 9.8 cM from foc-1 and 8.7 cM from foc-4, whereas foc-1 and foc-4 are closely linked at 1.1 cM. The identification of closely linked markers to resistance genes will facilitate marker-assisted selection for introgression of the race 3 resistance gene to susceptible chickpea lines.
