【摘要】 以2017—2020年江苏徐淮地区徐州农业科学研究所小麦科企联合体试验数据为依据，分析宁中麦1号的丰产性、稳产性、适应性及产量构成要素。结果表明：1）宁中麦1号较对照淮麦20的平均增产率为4.10%，平均增产点率为91.9%;2)3年间，宁中麦1号的产量在各试点的变异系数均小于对照淮麦20，且2年区域试验的高稳系数高于对照淮麦20;3）不同年份间的增产点数占总试点数的比例均大于或等于对照淮麦20，说明宁中麦1号是一个具有较好丰产性、稳产性和适应性的小麦品种；4）宁中麦1号的产量与穗数和千粒质量的相关性有统计学意义，其中穗数对产量的直接影响最大，千粒质量次之，穗粒数最小，单一产量要素通过其他要素对产量的影响均较小，说明可通过协同提高产量三要素来提高宁中麦1号的产量。更多还原

【Abstract】 The current research assessed the wheat variety Ningzhongmai No.1 for its yielding ability, yield stability, adaptability, and characteristics of yield components based on the data of the multi-site field trials of wheat varieties conducted by the science-enterprise consortium of Xuzhou Institute of Agricultural Sciences in Xuhuai area of Jiangsu Province from 2017 to 2020. The results are as follows. Firstly, the average yield of Ningzhongmai No.1 was 4.1% higher than that of the control wheat variety Huaimai 20, and its average yield was higher than the control on 91.9% of all the experimental sites. Secondly, in the three years, the coefficient of variation of the yield of Ningzhongmai No.1 was lower than that of Huaimai 20, and its high stability coefficient of the regional trials in two years was higher than that of Huaimai 20. Thirdly, compared with Huaimai 20, Ningzhongmai No.1 showed yield increases between different years on greater or equal proportions of sites in total experimental sites, indicating that Ningzhongmai No.1 has a high yielding ability, high yield stability, and strong adaptability. Fourthly, the yield of Ningzhongmai No.1 had statistically significant correlations with its panicle number and its 1 000-grain weight. Among the yield components, panicle number had the greatest direct impact on yield, followed by the weight of 1 000 grains, while the number of grains per panicle had the smallest impact; on the other hand, the single yield component had little impact on yield by influencing other factors. These results suggest that the yield of Ningzhongmai No.1 could be increased by synergetic improvement of the three yield components.更多还原
