【摘要】 用６０Ｃｏγ射线辐射春小麦８１３１，经多年系谱选择和培育，育成籽粒蛋白质和赖氨酸含量分别达２１．２０％和０．４８％的优异种质资源９２－３１０等品系。１９９２～１９９４年试验表明，９２－３１０平均产量可达６２０５．７８ｋｇ／ｈｍ２，较亲本高２０．５１％，较当地推广的丰产性品种低１５．３２％。９２－３１０是小麦品质育种的理想种质资源更多还原

【Abstract】 A spring wheat line 92-310, in which the content of grain protein and lysine is 21.2% and 0.48% respectively, was developed by 60 Co radiating variety 8131(protein content is 17.5%). The results in three site showed that the grain yield of 92-310 was 6 205 kg/hm 2in Hexi area and the yield was increased averagely by 20.51% more than that of its parent 8131. The yield of this line was decreased by 15.32% as compared with released cultivars, but protein content was significant higher than control. The 92-310 is a good genetic resource for improving wheat grain protein content, and it can be also used in field production.更多还原
