Abstract: 'Xinjing 1787' was bred by 'xin1709' as female parent and 'Jinjing 787' as male parent by Xinyang Academy of Agricultural Sciences. The progenies were selected continuously by pedigree method, and were selected for 8 generations in 5 years.In 2017 and 2018, the average rice yield of regional trials was 8 790.0 kg·hm-2 and 9 124.5 kg·hm-2 respectively, increased by 5.2% and 4.4% compared with the control variety '9 you 418'; In 2019, the average rice yield of production test was 9 541.5 kg·hm-2, increased by 6.77% compared with the control variety '9 you 418'.In 2017 and 2018, the comprehensive resistance index of rice blast was 1.75 and 2.5 respectively, and all of the highest loss rate of panicle neck blast was grade 1. This variety has the advantages of high and stable yield, strong resistance to rice blast, the application prospect is good.In September 2020, it was approved by Henan crop variety Approval Committee (approval number: yushendao 20200005). In January 2019, it was protected by the new plant variety right of the Ministry of agriculture (variety right No.: CNA20151574.3).
