Banded leaf-sheath blight(BLSB) caused by Rhizoctonia solani Kühn in maize(Zea mays L.) is an important disease in China and Southeast Asia.Knowledge of the identification of quantitative trait loci(QTLs) for tolerance to this disease will facilitate the development of maize cultivars(hybrids) resistance. A genetic linkage map covered 1 666 cM on total ten chromosomes,with an average interval length of 11.4 cM was constructed using 146 simple sequence repeat(SSR) markers and the software MAPMAKER version 3....
