Mapping quantitative trait loci for sheath blight disease resistance in Yangdao 4 rice

Z. H. Wen, Zeng, Y. X., Ji, Z. J., and Yang, C. D., Mapping quantitative trait loci for sheath blight disease resistance in Yangdao 4 rice, vol. 14, pp. 1636-1649, 2015.

Rice sheath blight (ShB), which is caused by Rhizoctonia solani, has become the most serious rice disease in China. Yangdao 4, a cultivar with partial resistance to ShB, was crossed with Lemont, a susceptible cultivar, to develop mapping populations that were used to analyze quantitative trait loci (QTL) that confer resistance to ShB. QTL analysis were performed in 3 environments (E1-E3) using 2 F2 and 1 F2:3 populations, respectively.
