  摘 要:榱私饣苹茨掀小麦品种主要农艺和品质性状的演变情况,利用2017―2021年国家小麦良种联合攻关黄淮南片生产试验数据,对其主要农艺性状和品质性状的变化进行统计和相关分析。结果表明:产量和株高随年份增加呈增长趋势,面团稳定时间是制约品质类型的关键因素。黄淮南片小麦产量约7 800 kg・hm-2,有效穗数约600万穗・hm-2,穗粒数在33粒以上,千粒质量44 g左右。相关性分析表明,提高有效穗数,并协调好穗粒数与千粒质量的关系,对提高产量更加有效。黄淮南片适宜株高80~85 cm,生育期以220 d为宜,黄淮南片麦区具有优质麦基因遗传多样性和丰富的品种类型,在今后的育种中,应加强对优质种质资源的发现和利用,采用多种育种手段,聚合多种优质丰产和抗病基因,改良面团稳定时间,协调主要农艺性状和品质性状间的关系,提高黄淮南片麦区小麦品种综合性能。

  Abstract:In order to understand the evolution of main agronomic and quality traits of wheat varieties in South Huang-huai region, the changes of main agronomic and quality traits of wheat varieties in South Huang-huai region were described statistics and correlation analyzed based on the production test data of National Joint Tacking of improved wheat varieties from 2017 to 2021. The results showed that the yield and plant height increased with the years, and the dough stabilization time was the key factor restricting the quality types. The yield of wheat in South Huang-huai region was about 7 800 kg・ha-1, the number of panicle was about 6 million panicles・ ha-1, the number of grains per panicle was more than 33, and the 1 000-grain weight was about 44 g. Correlation analysis showed that increasing the number of panicle and coordinating the relationship between grain number per panicle and 1 000-grain weight were more effective to increase the yield. South Huang-huai region was suitable for plant height 80-85 cm, growth period with 220 d advisable, South Huang-huai region of wheat with high quality mackey type because of genetic diversity and rich variety, breeding in the future, should strengthen the discovery and use of high quality germplasm resources, adopt a variety of breeding methods, polymerization a variety of high quality and disease resistance genes, and improved the dough stability time, to coordinate the relationship between main agronomic characters and quality characters and improve the comprehensive performance of wheat varieties in South Huang-huai region.
