俄罗斯大豆种质资源耐盐性鉴定

Identification of salt tolerance of Russian soybean germplasm resources

为选育出耐盐大豆品种和盐渍土的合理开发提供理论依据,以东北农业大学大豆遗传改良团队提供的俄罗斯大豆种质资源51份和黑河市逊克中俄农业科技合作园区提供俄罗斯种质资源21份作为试验材料,采用120mmol·L^(-1)NaCl进行盐胁迫水培试验,对表型数据进行处理、分析并计算出耐盐指数,进行综合评价。通过综合评价筛选出耐盐材料12份,感盐材料9份。其中,耐盐品种有俄C93-2、EC139-2、EC16-2、EC7-2、EC186-2、EC287-2、EC53、EC135-2、EC322-2、TEPEK、俄10135和阿尔沃,感盐品种有C110-2、C016-2、C240-2、C266-2、C131-2、EC54-2、EC323-2、利吉亚和E108ka457。综合评价结果与供试材料的实际耐盐表型情况较为一致。

In order to create a theoretical framework for the logical creation of salt-resistant soybean varieties and salt soil,taken 51 and 21 copies of Russian Soy germplasm resources provided by the Northeast Agricultural University Soybean Genetic Improvement Team,and by the Sino-Russian Agricultural Science and Technology Cooperation Park,respectively as the materials,a hydroponics test of salt stress with 120 mmol·L^(-1) NaCl was conducted,and the indexes for the phenotype data were processed and examined.Thorough comprehensive evalu-ation,twelve copies of salt-resistant materials and nine copies of salt-sensitive materials were screened out.Of which,Russia C93-2,EC139-2,EC16-2,EC7-2,EC186-2,EC287-2,EC53,EC135-2,EC322-2,Tepek,Russia 10135,and Alvy were of the salt-resistant varieties,while C110-2,C016-2,C240-2,C266-2,C131-2,EC54-2,EC323-2,Ligia and E108ka457 were of the salt-sensitive varieties.The results of the comprehensive analysis are in line with the test materials in the actual salt-resistance phenotype.
