高产、双抗型小麦新品种‘川麦51’产量、抗病性等特征分析

Analysis on the Yield Potential,Stability,Adaptability and Disease-resistance of 'Chuanmai51'

为了明确新品种的增产潜力和加快新品种的推广应用,实现新品种的应用价值,通过方差分析、多重比较等方法对小麦新品种——‘川麦51’的产量、抗病性等特征进行比较分析。‘川麦51’是四川省农科院作物研究所选育的一个中筋小麦品种,该品种在2年的区试试验中分别比对照增产12.6%和14.2%,生产试验中比对照增产11.4%。采用DPS软件进行区域试验分析的结果表明,‘川麦51’具有良好的丰产性、稳产性和稳定性。抗病性鉴定结果表明,‘川麦51’高抗条锈病和中抗白粉病,能够抵御频繁爆发条锈病和偶发白粉病的四川气候条件。综合评价认为‘川麦51’具有较高的推广应用价值。

In order to find out yield potential of new variety and accelerate the application of new variety,the author analyzed the yield,disease resistance,and some other characteristics of a new wheat variety＇ Chuanmai51 ＇ by variance analysis method,multiple comparison method,and so on.＇ Chuanmai51 ＇ was a new medium-gluten wheat breed by institute of crops,Sichuan academy of agriculture sciences.Compared to check variety,the yield of ＇ Chuanmai51 ＇ increased 12.6% and 14.2% in two years ＇ regional test,11.4% in one year ＇ s production test.Meanwhile ＇ Chuanmai51 ＇ had high yield stability and good adaptability.The results of resistance identification showed that ＇ Chuanmai51 ＇ possessed high resistant ability to wheat rust and had advantage in Sichuan climate condition which was good for rust fungus reproduction.In summery,＇ Chuanmai51 ＇ was a good variety with high application value.
