“…Similarly, a new BLP resistance gene identified in cultivar ‘PI96188’ (Han et al, 2007) was mapped on chromosome 10 (LG O) by Kim et al (2011). In another study, genome‐wide analysis of soybean genotypes identified 13 SNPs significantly associated with BLP disease resistance and distributed among five linkage groups (da Fonseca et al, 2022).…”

Bacterial leaf pustule (BLP) caused by Xanthomonas axonopodis pv. glycines (Xag) is a serious soybean disease. A BLP resistant genotype ‘TS‐3’ was crossed with a BLP susceptible genotype ‘PK472’, and a segregating F2 mapping population was developed for genetic analysis and mapping. The F2 population segregation pattern in 15:1 susceptible/resistance ratio against Xag inoculum indicated that the resistance to BLP in ‘TS‐3’ was governed by two recessive genes. A total of 12 SSR markers, five SSR markers located on chromosome 2 and seven SSR markers located on chromosome 6 were identified as linked to BLP resistance. One of the resistance loci (r1) was mapped with flanking SSR markers Sat_183 and BARCSOYSSR_02_1613 at a distance of 0.9 and 2.1 cM, respectively. Similarly, SSR markers BARCSOYSSR_06_0024 and BARCSOYSSR_06_0013 flanked the second locus (r2) at distances of 1.5 and 2.1 cM, respectively. The identified two recessive genes imparting resistance to BLP disease and the SSR markers tightly linked to these loci would serve as important genetic and molecular resources to develop BLP resistant genotypes in soybean.
