摘 要：该研究是以我国目前的优良主栽品种为受体亲本，以来源于全球主要产稻国家的优良品种资源为供体亲本，在创造大规模导入系的基础上，聚合绿色超级稻相关性状（抗病虫、氮磷高效利用、节水抗旱和高产优质）；开发适用性分子标记，通过标记辅助选择进行多性状（基因）累加，克服常规分子标记育种转移单一基因的低效率，打破“遗传累赘”，创造“绿色超级稻”未来亲本；通过对不同优良性状基因的聚合，培育“绿色超级稻”。

Abstract：In this study， the elite major rice varieties were used as recieptor and rice germplasm around the world were used as donors for developing in large scale the introgressed lines which were applied for pyramiding green traits of Green Super Rice， e.g. tolerant to disease and pests， high utilization effiency of N and P， drough tolerance， high yield and good quality. The practical molecular markers were developed to assist the selection for multiple traits pyramiding， which overcame the low effiency by single gene introgression in traditional molecular marker assisted breeding and broken the linkage drag as well as developing the propestive parents of Green Super Rice. The Green Super Rice varieties have been developed by pyramiding different favorable genes of multiple traits.
