Abstract

Spot blotch (SB) caused by the fungus Cochliobolus sativus, is an economically important disease on barley worldwide. Molecular analysis of SB resistance using quantitative trait locus (QTL) analysis can improve the efficiency of the breeding process. In the current work, and to accelerate development of SB-resistant barley cultivars, AFLP markers linked to SB resistance have been identified by using F2 recombinant inbred lines derived from a cross between the resistant barley cv. Banteng and the susceptible cv. WI2291. Single marker analysis (SMA) based on t-test revealed that out of 82 AFLP markers; five AFLP markers AAC × CTG (700 bp), ACT × CAT (600 bp), ACT × CAT (400 bp), ACT × CTG (550 bp) and AGG × CAG (490 bp) were identified. The data showed that SMA-based t-test could be a useful analysis for dominant markers such AFLP in breeding programs, and that the AFLP detected markers can be employed in genomics-assisted breeding for selection of SB-resistant barley genotypes.
