摘要
利用2012—2021年间国家小麦区域试验长江中下游组212份参试品系的主要农艺性状区试结果,分析其近10年的演变规律。结果表明,该区域小麦产量和穗粒数先减后增、有效穗数明显减少、千粒重和株高不断增加、生育期基本保持平稳。今后,长江中下游麦区产量应当在保持现有产量结构的基础上,注意提高千粒重,适当降低穗粒数,培育早熟品种为主,更有利于该麦区产量提升。
Based on main agronomic traits of 212 materials of the national wheat regional trial in the middle and lower reaches of the Yangtze River Valley from 2012 to 2021, the evolution law of the traits was analyzed.The results showed that the wheat yield and the number of grains per spike decreased first and then increased as the time went on, the number of effective spikes decreased significantly, 1000-grain weight and plant height continued to increase, and the duration remained basically stable. In the future, on the basis of maintaining the current yield structure in the middle and lower reaches of the Yangtze River Valley wheat region, 1000-grain weight should be increased, the number of grains per spike should be appropriately reduced, and earlymaturing varieties should be cultivated, which will be more conducive to improving the yield in this wheat region.
