摘　　要：为了确定黄淮海地区大豆育成品种(系)的结瘤能力差异,本研究以1970—2020年黄淮海地区育成的143份大豆品种(系)为试验材料,在盆栽条件下接种根瘤菌菌株USDA110,以单株根瘤数、单株根瘤干重作为结瘤能力鉴定指标,筛选结瘤能力强和弱的大豆种质。同时比较黄淮海地区不同省市参试材料的结瘤差异,分析结瘤差异与产量、育成年份、蛋白含量、油分含量和蛋油总含量的相关性。结果表明:参试的不同大豆品种(系)间单株根瘤数最大值为35个,最小值为6个,均值为17个,单株根瘤干重最大值为124.89 mg,最小值为26.44 mg,均值为53.81 mg。筛选出结瘤能力前5%品种(系),包括安豆1311、灌云大四粒、沿大粒、太丰6号、商豆7号、黄豆ZDD08405和08Y观205,作为培育强结瘤能力品种的亲本。不同地域来源参试材料间结瘤能力也存在差异:江苏省材料单株根瘤干重和单株根瘤数最大,分别为64.30 mg和20个;山东省材料单株根瘤干重最小,为48.50 mg;山西省和安徽省材料单株根瘤数最小,均为15个。单株根瘤干重与籽粒蛋白含量成正相关。研究结果可为黄淮海地区大豆育种提供强固氮亲本材料。In order to determine the difference in nodulation ability of soybean varieties (lines) bred in the Huang-Huai-Hairegion, 143 soybean varieties (lines) were used as materials grown in the Huang-Huai-Hai region during 1970 - 2020, andinoculated with rhizobia strain USDA110 under pot conditions. Root nodule dry weight of a single plant was used as theidentification index of nodulation ability to screen soybean germplasms with high or low nodulation ability. Meanwhile, thenodulation differences of the tested materials from different provinces and cities in the Huang-Huai-Hai region were compared.The correlation between the nodulation differences and yield, released year, protein content, oil content and total protein-oilcontent were analyzed. The results showed that the maximum number of nodules per plant among different soybean varieties(lines) tested was 35, the minimum was 6, and the average was 17. The maximum dry weight of root nodules per plant was124. 89 mg, and the minimum was 26. 44 mg, with an average value of 53. 81 mg. The top 5% varieties (lines) with thehighest nodulation ability were selected as the parents for cultivating varieties with high nodulation ability, including Andou1311, Guanyundasili, Yandali, Taifeng 6, Shangdou 7, Huangdou ZDD08405 and 08Yguan 205. The dry weight and numberof root nodules per plant in Jiangsu province were the largest, 64. 30 mg and 20, respectively. The dry weight of root nodulesin Shandong province was the smallest, 48. 50 mg. The number of root nodules in Shanxi and Anhui provinces was thesmallest, the minimum number was 15, and the dry weight of nodules per plant was positively correlated with the seed proteincontent. The research results can provide useful nitrogen-fixing parent materials for soybean breeding in Huang-Huai-Hairegion.
