Rice blast is one of the most important diseases rice, causing significant economic losses to agricultural production. A new gene, Pigm-1, which allelic Pigm, was cloned from Shuangkang 77009 using map based cloning. However, it unclear whether there a difference in resistance spectrum between Pigm and Pigm-1. In this study, 195 rice isolates collected different areas Fujian Province, Pigm-1 single gene lines were inoculated test their resistance. There only fungus JL-37 that showed differential response lines, while remaining 194 no difference. To further explore application range resistant R20-4 containing used as donor, sensitive sticky S19-118 receptor. The hybrid F1 first backcrossed with molecular marker-assisted selection breeding method, strain selected continue backcross until BC3F1. material, Xiannuo 23, developed confirmed by laboratory field tests. This material can be broadly for future cultivars reduce loss
