摘要：为选择适宜泰州地区栽培环境的产量高、适应性强、稳定性好的小麦品种，本文选取近年来通过国审或苏审在江苏地区种植的20个小麦品种进行同田对比试验，对小麦品种的农艺性状和产量性状等进行相关分析。结果表明：不同基因型小麦品种间农艺性状和实际产量差异显著，其产量变幅在5150～ 7350 kg/hm²之间，平均值为6095kg/hm²。‘华麦8号、‘宁麦22和‘扬麦27实际产量优势明显，其中‘华麦8号实际产量较其他品种平均值超过1200 kg/hm²，‘华麦8号和‘扬麦27的容重均在800 g/L以上。根据田间综合表现，认为‘华麦8号、‘宁麦22和‘扬麦27的丰产性较好，抗倒性、抗病性中等，生育期适中，经济性状突出，可以在泰州地区大面积推广种植。该研究为筛选出适宜泰州地区推广的小麦品种资源提供了一定的科学依据。

Abstract：To select suitable wheat varieties with high yield，strong adaptability and good stability for the cultivation environment in Taizhou area，20 wheat varieties which were approved by National Crop Variety Certification or by Jiangsu Province and planted in Jiangsu in recent years were taken for field comparison test on correlation analysis of agronomic traits and yield traits of wheat varieties. The results show that the agronomic characters and actual yield of wheat varieties with different genotypes are significantly different，and the yield varies between 5150-7350 kg/hm²，with an average yield of 6095 kg/hm². The actual yield of ‘Huamai 8，‘Ningmai 22and ‘Yangmai 27have obvious advantages，among which，the actual yield of ‘Huamai 8is more than 1200 kg/hm²compared with that of other varieties，and the bulk density of ‘Huamai 8and ‘Yangmai 27are more than 800 g/L. According to the comprehensive performance in field，‘Huamai 8，‘Ningmai 22and ‘Yangmai 27have better yield，medium lodging resistance and disease resistance，reasonable growth period and outstanding economic characters，and could be widely planted in Taizhou area.

0引言

小麥是世界上主要的粮食作物之一，也是中国第三大粮食作物，种植面积达到粮食总面积的22%，其高产稳产关系着中国的粮食安全[1-4]。泰州地区小麦种植品种繁多，小麦种植面积趋于稳定，对以提高单产增加粮食总产具有重要意义[5]，广大农户对小麦品种特性缺乏认识，依据农艺性状和产量进行选育和推广优良品种是达成小麦高产稳产目标的有力措施[6-7]。不同小麦品种因遗传特性差异会有不同氮素吸收和利用特点，在同一生态点通过控制外在相关栽培环境条件，可筛选出适宜该点的优良品种。……
