摘要
粳优586是辽宁省水稻研究所以139A为母本、C586为父本,经人工杂交配组而成的优质粳型杂交水稻新组合。综合抗病性表现优异,米质达到国标优质三级。2012~2013年区域试验平均产量9.48 t/hm^(2),比对照津原85增产5.43%。2014年生产试验平均产量10.36 t/hm^(2),比对照津原85增产8.44%。2015年9月通过国家农作物品种审定委员会审定。总结介绍了粳优586的栽培及制种技术要点。
Gengyou-586,a new hybrid rice combination with high quality,was developed by Liaoning Rice Research Institute with 139A as female parent and C586 as male parent.The comprehensive disease resistance performance was excellent,and the rice quality reached the national standard grade 3.From 2012 to 2013,the average yield of regional experiment was 9.48 t/hm^(2),which was 5.43%higher than that of the control.In 2014,the average yield was 10.36 t/hm^(2),which was 8.44%higher than that of the control.In September 2015,it was approved by the National Crop Varieties Certification Committee.The cultivation and seed production techniques of Gengyou-586 were summarized.
