摘要： 旨在为小麦新品种审定，特别是为其今后的市场推广提供了参考依据。利用R语言统计模型，分析2016—2017年度国家黄淮南片小麦区试试验结果，评价17个冬小麦品种稳定性和适应性。单变量参数分析显示，‘新麦35’、‘周麦36’、‘中育1220’、‘郑麦103’和‘泛育麦17’的CV值较小，表明这5个品种静态稳定性较好；‘新麦35’、‘周麦18’、‘泉麦31’、‘郑麦16’、‘周麦36’和‘郑麦103’的Shukla变异系数较小，表明这6个品种平均动态稳定性好；‘新麦35’、‘郑麦103’、‘周麦36’、‘郑麦16’和‘禾丰3号’的Pi值小，说明这些品种产量高且试点间稳定性好，普遍适应性强。‘新麦35’、‘郑麦103’和‘周麦36’在各个试点的适应性和稳定性较好，适于黄淮南片推广应用。

Abstract: This study aims at providing a reference for the approval of new wheat varieties and marketing in the future. By using R language statistical model, the experimental results of wheat region in the Southern Huanghuai Area from 2016 to 2017 were analyzed, the stability and the adaptability of 17 wheat varieties were evaluated. The univariate parametric analysis showed that the CV value of‘Xinmai35’,‘Zhoumai36’, ‘Zhongyu1220’,‘Zhengmai103’and‘Fanyumai17’were smaller, which indicated that the static stability of these five varieties were better than that of the others. The Shukla variable coefficient of‘Xinmai35’, ‘Zhoumai18’, ‘Quanmai31’, ‘Zhengmai16’, ‘Zhoumai36’ and‘Zhengmai103’ were smaller, which suggested that the dynamic stability of these six varieties were better than that of the others. The Pi value of ‘Xinmai35’,‘Zhengmai103’,‘Zhoumai36’,‘Zhengmai16’ and‘Hefeng No.3’ were smaller, which indicated that these varieties had high yield, good stability among locations, and strong adaptability. The adaptability and stability of‘Xinmai35’,‘Zhengmai103’and‘Zhoumai36’were better in each location, and were suitable for planting in the Southern Huanghuai Area.
