籽粒低镉高产早稻品种筛选OA
Preliminary study on screening early rice varieties for low cadmium accumulation in grains and high yield
[目的]通过筛选江西省籽粒低镉高产早稻品种,为水稻籽粒低镉新品种的选育与推广提供材料基础.[方法]选择江西省主推的59个早稻品种为材料,采用田间小区试验,测定水稻产量、糙米镉含量和镉富集系数,比较不同水稻品种分别在轻度和中度镉污染田中的镉富集差异.[结果]轻度镉污染田中,不同供试品种产量为5.1～8.9 t/hm2,产量差异显著;中度镉污染田中,产量为4.45～8.87 t/hm2,产量差异更加显著.轻度镉污染田中,各品种糙米镉含量为0.017～0.263 mg/kg,其中有50个品种均低于国家限量标准(0.200 mg/kg);中度镉污染田中,各品种糙米镉含量为0.028～0.484 mg/kg,其中有16个品种均低于国标.轻度镉污染田中,各品种糙米镉富集系数为0.06～0.85;中度镉污染下,各品种糙米镉富集系数为0.06～1.03.[结论]综合考虑水稻产量与糙米镉累积情况,初步筛选出轻度镉污染田适宜种植的籽粒低镉高产品种为中安7号、中安2号、启两优2216、中嘉早17、安优5020、兵两优518、陵两优739、洪优早1号、金珍优早丝、优I527等10个品种,中安2号、洪崖早2号、启两优2216、中安7号、洪优早1号、中安早35和中嘉早17可作为江西稻区中度镉污染田适宜种植的籽粒低镉高产水稻品种.
[Objective]This study aims to screen early rice varieties with low cadmium(Cd)content in grains and high yield in Jiangxi Province,so as to provide a material basis for the breeding of new rice varieties with low Cd in grains.[Method]Fifty-nine early season rice varieties mainly promoted in Jiangxi Province were selected as test materials.Field plot experiments were conducted to determine rice yield,Cd content in brown rice and Cd enrichment coefficient,and to compare the differences in Cd enrichment among different rice varieties in slightly and moderately Cd-contaminated fields,respectively.[Result]In slightly Cd-contaminated fields,the yield range of different tested varieties was 5.1-8.9 t/hm²,with significant differences in yield;in moderately Cd-contaminated fields,the yield range was 4.45-8.87 t/hm²,and the yield differences were more significant.In slightly Cd-contaminated fields,the Cd content in brown rice of each variety ranged from 0.017 to 0.263 mg/kg,among which 50 varieties had Cd content lower than the national limit standard(0.200 mg/kg);in moderately Cd-contaminated fields,the Cd content in brown rice of each variety ranged from 0.028 to 0.484 mg/kg,among which 16 varieties met the national standard.In slightly Cd-contaminated fields,the Cd enrichment coefficient of brown rice for each variety ranged from 0.06 to 0.85;under moderate Cd contamination,the Cd enrichment coefficient of brown rice for each variety ranged from 0.06 to 1.03.[Conclusion]Considering both rice yield and Cd accumulation in brown rice comprehensively,10 varieties,including Zhong'an 7,Zhong'an 2,Qiliangyou 2216,Zhongjiazao 17,Anfengyou 5020,Bingliangyou 518,Lingliangyou 739,Hongyouzao 1,Jinzhenyouzaosi and You I 527,were screened out as suitable low-Cd and high-yield grain varieties for planting in slightly Cd-contaminated fields.Zhong'an 2,Hongyazao 2,Qiliangyou 2216,Zhong'an 7,Hongyouzao 1,Zhong'anzao 35 and Zhongjiazao 17 can be used as suitable low-Cd and high-yield grain rice varieties for moderately Cd-contaminated fields in Jiangxi rice-growing areas.
