摘 要：該研究是以我國目前的優(yōu)良主栽品種為受體親本，以來源于全球主要產(chǎn)稻國家的優(yōu)良品種資源為供體親本，在創(chuàng)造大規(guī)模導(dǎo)入系的基礎(chǔ)上，聚合綠色超級(jí)稻相關(guān)性狀（抗病蟲、氮磷高效利用、節(jié)水抗旱和高產(chǎn)優(yōu)質(zhì)）；開發(fā)適用性分子標(biāo)記，通過標(biāo)記輔助選擇進(jìn)行多性狀（基因）累加，克服常規(guī)分子標(biāo)記育種轉(zhuǎn)移單一基因的低效率，打破“遺傳累贅”，創(chuàng)造“綠色超級(jí)稻”未來親本；通過對(duì)不同優(yōu)良性狀基因的聚合，培育“綠色超級(jí)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.

Key Words：Green Traits；Molecular Design；Pyramiding Breeding
