为了解江苏省近十年来审定小麦品种的农艺、品质性状演变情况,分析了2014-2023年江苏淮北及淮南地区审定的90和95个小麦品种的13个农艺、品质性状及变化规律。结果发现,2014-2023年,淮北地区审定小麦品种以中筋为主,而淮南地区重心逐渐向中强筋及强筋小麦转移。淮南地区小麦品种选育较多利用本地种质资源,对异地种质资源利用较少,淮北地区则较多利用山东及河南地区小麦资源,直接利用频率较高的小麦品种有镇麦9号(17次)、镇麦168(14次)、郑麦9023(13次)、矮抗58(11次)。淮北和淮南审定小麦品种的产量、株高、穗粒数、千粒重均呈上升趋势;有效穗数发展平稳,生育期呈下降趋势。两地小麦品种的品质变化存在较大差异,淮北地区小麦品种的容重、蛋白质含量、湿面筋含量及吸水率与淮南小麦品种的容重及吸水率均呈上升趋势,淮南地区小麦蛋白质含量及湿面筋含量呈下降趋势,且逐渐低于淮北地区;两地小麦的最大拉伸阻力及拉伸面积均发展平稳,面团稳定时间呈下降趋势。通过相关性分析发现,淮北地区小麦产量与其三要素相关性表现为千粒重>穗粒数>有效穗数;淮南地区小麦产量与其三要素相关性表现为千粒重>有效穗数>穗粒数。这说明过去十年江苏小麦产量育种均以提高千粒重为主要方向,今后可从穗粒数和有效穗数方面挖掘增产潜力;淮北地区应尝试分区发展强筋及弱筋小麦,淮南地区的品种选育应进一步引进新的优质种质资源;两地在审定品种增多的同时兼顾增产率的提高及品质的优化,选育符合市场需求的优质、高产小麦。

To understand the evolution of agronomic and quality traits of wheat varieties approved in Jiangsu Province over past decade, thirteen agronomic and quality traits of 90 and 95 wheat varieties approved in Huaibei and Huainan areas of Jiangsu Province from 2014 to 2023 were analyzed. The results showed that the wheat varieties approved in Huaibei from 2014 to 2023 were primarily medium-gluten types, while the focus in Huainan gradually shifted toward medium- and strong-gluten varieties. Local germplasm resources were more frequently utilized in variety breeding within the province compared to external sources, with Zhenmai 9(17 times), Zhenmai 168(14 times), Zhengmai 9023(13 times), and Aikang 58(11 times) being the most commonly used. The yield, plant height, grain number per spike, and 1 000-grain weight of the approved wheat varieties in both regions showed an upward trend, while the effective panicle number remained stable, and the growth period exhibited a downward trend. There are great differences in the quality changes of wheat varieties between the two places. In the Huaibei region, grain test weight, protein content, wet gluten content, and water absorption increased rapidly. The protein content and wet gluten content of wheat in Huainan showed a downward trend, and were gradually lower than those in Huaibei area. The maximum tensile resistance and tensile area of wheat in the two regions showed a stead trend, while dough stability time showed a downward trend. Correlation analysis revealed that in Huaibei, the correlation between wheat yield and its three components ranked as: 1 000-grain weight>grain number per spike>effective spike number. In Huainan, the correlation ranked as: 1 000-grain weight>effective panicle number>grain number per panicle. This indicates that the main goal of wheat yield breeding in Jiangsu Province in the past ten years was to improve the 1 000-grain weight, and the potential of yield increase can be continuously improved from the aspects of grain number per spike and effective spike number in the future. Huaibei area should try the feasibility of developing strong gluten and weak gluten wheat in different regions, and Huainan area should further introduce new high-quality germplasm resources. While increasing the number of approved varieties, the two regions should take into account the improvement of yield increase rate and the optimization of quality, and breed high-quality and high-yield wheat varieties that meet market demand.
