陇春24小麦品种的丰产性和稳定性分析

目的]为了全面了解陇春24小麦品种的丰产性能。方法]依据2004～2005年甘肃省水地春小麦区域试验资料,运用联合方差分析法和高稳系数法(HSC),对陇春24和其他21个品种的丰产性和稳产性进行了分析,同时利用灰色关联度分析法对2004￣2005年小麦区域试验中相同地点的4个品种进行了综合评价。结果]联合方差分析结果表明,2004年区域试验中,陇春24平均产量为8624.40 kg/hm2,较对照高原602增产6.65%;2005年区域试验平均产量为7 627.35 kg/hm2,较对照增产11.65%。HSC分析表明,陇春24、91043的高稳系数与产量间的相关系数为-0.8515,高稳系数与变异系数的相关系数为0.7845,高稳系数与标准差间的相关系数为0.4806。结论]陇春24小麦品种丰产稳产性好,具有较大的增产潜力,在甘肃河西及沿黄灌区适应性较好。

Analysis of Productivity and Stability on Wheat Variety Longchun 24

Objective] The purpose was to know the productivity performance of wheat variety Longchun 24 roundly.Method] Based on regional experimental data of spring wheat in irrigated land of Gansu Province in 2004~2005,productivity and stability of Longchun 24 and other 21 varieties were analyzed by using combined variance analysis(CVA) method and high stability coefficient(HSC) method.The comprehensive evaluation of 4 varieties in the same sites of wheat regional experiment in 2004~2005 was done with grey relativity analysis method at the same time.Result] CVA analysis indicated that compared with CK(Gaoyuan 602),average yield of Longchun 24 was 8 624.4 kg/hm2 and increased 6.65 % in 2004 regional experiment;that in 2005 were 7 627.35 kg/hm2,increased by 11.65 %.HSC analysis indicated that the relative coefficient between high steady coefficient and yield of Longchun 24 and 91043 was-0.851 5,the relative coefficient between high-steady coefficient and variation coefficient was 0.784 5 and the relative coefficient between high steady coefficient and standard deviation was 0.480 6.Conclusion] Wheat variety Longchun 24 possessed good productivity and stability,bigger increasing potential and better adaptability in Hexi area of Gansu and irrigated area along Yellow River.
