江苏省淮南小麦品种农艺性状与产量指标相关性研究

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6095 kg/...

Correlation Between Agronomic Traits and Yield Indexes of Huainan Wheat Variety in Jiangsu Province

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 22’ and ‘Yangmai 27’ have obvious advantages, among which, the actual yield of ‘Huamai 8’ is more than 1200 kg/hm ² compared with that of other varieties, and the bulk density of ‘Huamai 8’ and ‘Yangmai 27’ are more than 800 g/L. According to the comprehensive performance in field, ‘Huamai 8’, ‘Ningmai 22’ and ‘Yangmai 27’ have better yield, medium lodging resistance and disease resistance, reasonable growth period and outstanding economic characters, and could be widely planted in Taizhou area.
