摘要
通过对793份大豆种质资源进行芽期耐盐性鉴定,以及部分品种进行苗期和全生育期耐盐性鉴定,筛选出芽期、苗期及全生育期耐盐品种117份、41份和35份。其中有3个品种(WDD1812,晋豆23和晋遗38号)在芽期和苗期都表现高耐盐性;1个品种(晋豆23)在芽期、苗期、全生育期都表现高耐盐性。晋豆23还具有高度抗旱、高抗病毒病、耐红蜘蛛等特性,而晋遗38号来源于晋豆23。芽期或苗期耐盐性为一级的品种,如中黄13、新大豆1号、陕豆125、东农46、东大1号、合丰38等,不但具有高耐盐性,而且具有很好的丰产性,有些品种还具有优质和抗逆等优异的农艺性状。本研究筛选到的耐盐品种将为大豆耐盐育种提供优异的种质资源,同时对大豆全生育期耐盐性鉴定的指标和方法的探讨,将为大豆耐盐性鉴定科学方法的建立提供重要信息。
Seven hundred and ninety-three soybean varieties were evaluated for salt tolerance during the germination,seedling stage,and later growth.Among tested varieties,117 and 41 with salt tolerance（Grade 1 and 2）were identified at the germination stage and the seedling stage respectively.Two hundreds and eighty soybean varieties were evaluated for salt tolerance in the whole growing season in 2009 and 2010,and 35 varieties were more salt tolerant than salt-tolerant control soybeans in two years.Three varieties,WDD1812,Jindou 23,and Jinyi 38 showed high salt tolerance at the germination stage and the seedling stage.Besides these two stages,Jindou 23 was more salt tolerant than the control soybeans in the whole growing season.Besides the slat tolerance,some varieties,such as Jindou 23,Jinyi 38,Zhonghuang 13,Xindadou 1,Shandou 125,Dongnong 46,Dongda 1,and Hefeng 38 were high yield and quality.The excellent salt-tolerant germplasm resources screened in this study provide the genetic materials for soybean breeding to improve salt tolerance.This paper described the methods and index of evaluation for salt tolerance in the whole growing season,providing the basis for standard method of evaluation of salt tolerance in soybean.
