摘要
[目的]为优质强筋小麦新品种新麦58在黄淮海南片麦区的推广提供科学依据。[方法]利用2019—2022年度国家冬小麦品种试验黄淮海南片水地组区域试验和生产试验数据,对新麦58的农艺性状和品质、产量构成、丰产性、相关性进行分析。[结果]新麦58在国家冬小麦品种黄淮海南片水地组3年试验中成穗率较高,有效穗数为638.59万穗/hm 2,穗粒数33.90粒/穗,千粒重43.44 g,生产试验平均产量9264.6 kg/hm 2,比对照增产5.68%,增产点率100%。品质结果达到强筋小麦品质标准。产量三要素相关性和直接通径系数结果均表明,穗粒数是影响新麦58产量的主要因素。[结论]生产上应保证适量的有效穗数,主攻穗粒数,稳定千粒重,进一步挖掘新麦58的高产潜力。
[Objective]The aim was to provide scientific basis for the popularization of a new wheat variety Xinmai 58 with high quality and strong glutenin the southern wheat area of Huang-Huai-Hai.[Method]Based on the data of regional test and production test of Water Land Group in south Huang-Huai-Hai area of the national winter wheat variety test from 2019 to 2022,we analyzed the agronomic characters and quality,yield composition,yield and correlation of Xinmai 58.[Result]The heading rate of Xinmai 58 was higher in the 3-year experiment of Water Land Group in south Huang-Huai-Hai.The effective panicle number was 6385900 panicles/hm 2 with 33.90 grains per ear,43.44 g thousand-grain weight,9264.6 kg/hm 2 average yield of production test.The yield was 5.68%higher than that of the control,and the increase point rate was 100%.The quality result reached the quality standard of strong gluten wheat.The quality result reached the quality standard of strong gluten wheat.The correlation of three factors of yield and direct path coefficient showed that grains per ear was the main factor affecting Xinmai 58.[Conclusion]We should ensure proper effective ears,pay more attention to grains per ear,stabilize the 1000-grain weight,and further explore the high-yield potential of Xinmai 58.
