水稻新品种松辽677选育技术创新探析

Innovation of Breeding Technology of New Rice Variety Songliao-677

松辽677是以春承101为母本,众禾一号为父本,配组杂交,双亲优势遗传基因与有利遗传基因互补聚合重组为技术基础材料,经改进的系谱法与穿梭育种技术育成。在吉林省属中熟品种,在北方稻区为早粳晚熟品种,2019~2020年吉林省区域试验平均产量9263.96 kg/hm^(2),比对照品种吉玉粳平均增产7.4%。2020年吉林省生产试验平均产量9623.90 kg/hm^(2),比对照品种吉玉粳平均增产8.6%,增产点比例100%。

Songliao-677 was bred from Chuncheng-101 as the female parent and Zhonghe-1 as the male parent by cross breeding.The technical base material was complementary polymerization and recombination of dominant and advantageous genes.It is a medium-mature variety in Jilin Province,and an early-japonica late-ripening variety in the northern rice region.The average yield of the regional test in Jilin Province from 2019 to 2020 is 9263.96 kg/hm^(2),which is 7.4%higher than that of the control variety Jiyugeng.In 2020,the average yield of jilin Province production test was 9623.90 kg/hm^(2),which was 8.6%higher than that of the control variety Jiyugeng,and the percentage of yield increased by 100%.
