摘要
采用高稳系数法（HSCi）和适应性参数法（αi），结合变异系数法（CV），产量平均数（x^-）及回归系数法（b），对2004～2006年辽宁省新审定的41个玉米品种和4个高淀粉玉米品种在辽宁中北部不同地点环境下的高产稳产性能及适应性能进行综合分析。结果表明，高产，稳产，适应性强的品种有沈玉24，沈玉21，东单90，华单208和辽单526。
In order to enhance our province comprehensively the maize yield, the full display has nurtured the improved maize varieties yield potential,uses the variety arrangement reasonably . Using the method that is high stability coefficient and adaptive parameter,with the coefficient of variation of , the average yield and regression coefficient. Stability and adaptability of approved 41 the new maize varieties and 4 high-starch maize in the middle and northern part of Liaoning comprehensive analysis of the performance in the 2004 - 2006. The results showed that Chen Yu 24, Chen Yu 21 , Dongdan 90, huadan 208, liaodan526 have the higher production increase potential,may in the experimentand the peripheral locality big area promotion.
