陇东旱地冬小麦新品种丰产稳产性分析

Analysis on high and stable yield ability of dry-land winter wheat in east Gansu

采用回归系数法、稳定性参数法和高稳系数法对参加甘肃省2002～2004年度陇东片冬小麦区域试验的11个品种(系)进行丰产稳产性综合分析。结果表明:高稳系数法是一种简便有效评价作物品种丰产稳产性的好方法,较其他两种方法客观、可靠;陇育215、陇鉴301丰产稳产,是陇东旱地极具推广前景的品种。

This paper analyses the high and stable production ability of 11 dry-land wheat varieties in the regional tests in east part of Gansu province in 2002~2004 by adopting the methods of regression coefficient, stability parameter and high and stable yield coefficient. The result shows: the high and stable coefficient is a simple and effective evaluation method prior to the others; Longyu 215 and Longjian 301 are high and stable in production ability, which are the best varieties to be extended in the dry-land in east Gansu province.
