摘要
‘信粳1787’是信阳市农业科学院利用‘新1709’为母本,‘金粳787’为父本进行杂交,后代采用系谱法连续选择,历经5年8代选育而成。该品种在2017年和2018年区域试验中稻谷平均产量分别为8790.0 kg·hm-2,9124.5 kg·hm-2,比对照品种‘9优418’分别增产5.2%,4.4%;2019年生产试验,稻谷平均产量9541.5 kg·hm-2,比对照品种‘9优418’增产6.77%。2017年和2018年稻瘟病综合抗性指数分别为1.75,2.5,穗颈瘟损失率最高级均为1级。该品种具有高产稳产、抗稻瘟病强等显著优点,应用前景好。2020年9月通过河南省农作物品种审定委员会审定(审定编号:豫审稻20200005),2019年1月获农业部植物新品种权保护(品种权号:CNA20151574.3)。
’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 and2018,the average rice yield of regional trials was 8790.0 kg·hm-2 and 9124.5 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 9541.5 kg·hm-2,increased by6.77%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).
