    摘要:

    本研究以9311为高镉对照，湘晚籼12号为相邻低镉对照，2015年~2017年经田间鉴定筛选出的15份镉低积累水稻资源为参试材料，鉴定精米的相对降镉率并筛选出年度间相对降率差异不显著的资源；采用45对SSR引物检测15份资源的遗传多样性，提出遗传距离大且相对降镉率高的育种可用资源。2018年试验结果表明，15份低镉水稻资源的精米镉含量都低于湘晚籼12号，相对降镉率大于50%的有10份，变幅为50.8%~83.5%；小于50%的有5份，变幅是1.9%~49.8%；2019年试验结果表明，7份生育期相近的资源，相对降镉率都大于50%，变幅是60.1%~78.7%；2年试验结果的综合分析表明，4份低镉资源7(BS82)、14（X211）、19(7W172)、20(7W216)的镉积累在年度间无显著性差异，且相对降镉率都在50%以上。15份镉低积累资源总体遗传多样性较为丰富（Na=4.311、Ne=3.257、Ho=0.041、He=0.657、I=1.207、Nei's=0.639、PIC=0.612）；遗传相似系数（GS）的平均值为0.377，亲缘关系较远，材料7和材料14、材料7和材料19（20）、材料14和材料19（20）的遗传相似系数分别为0.319、0.447、0.426。由上说明BS82、X211、7W172、7W216是镉低积累新品种选育的可利用的宝贵资源。

    Abstract:

    the relative Cd-reduction rate of polished rice and screened the resources with no significant difference in the annual relative Cd-reduction rate. In addition, 45 SSR markers were used to detect the genetic diversity of 15 rice accessions, in order to identify the resources available for breeding with a great genetic distance and high relative Cd-reduction rate. The results showed that in 2018, Cd content in 15 low-Cd polished rice was lower than cv. Xianwanxian 12. Ten samples represented relative Cd-reduction rate of more than 50%, ranging from 50.8% to 83.5%, while 5 samples were less than 50%, ranging from 1.9% to 49.8%. In 2019, the relative Cd-reduction rate in 7 rice samples with similar growth period was higher than 50%, variable from 60.1% to 78.7%. Based on the two-year test results, no significant difference was found among four low-Cd rice samples 7 (BS82), 14 (X211), 19 (7W172), 20 (7W216), and the relative Cd-reduction rate was higher than 50%. The overall genetic diversity in 15 low Cd-accumulating rice population indicated relatively abundant (Na=4.311, Ne=3.257, Ho=0.041, He=0.657, I=1.207, Nei's=0.639, PIC=0.612). The mean genetic similarity (GS) was 0.377, suggesting distant genetic relationship. For examples, the GS in pairs of samples 7 and 14, samples 7 and 19 (20) as well as samples 14 and 19 (20) were 0.319, 0.447 and 0.426, respectively. Therefore, four rice germplasm resources
