【摘要】 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9 263.96 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%。更多还原

【Abstract】 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 9 263.96 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 9 623.90 kg/hm~2, which was 8.6% higher than that of the control variety Jiyugeng, and the percentage of yield increased by 100%.更多还原
