辽宁花生品种区域化研究

Study on Peanut Variety Regionalization in Liaoning Province

[目的]对辽宁省花生品种的产量、稳产性、适应性区划进行研究,以期对辽宁省花生单产水平的提高提供理论依据。[方法]利用8个品种在省内7个地点进行试验,各处理实测产量,经方差分析、稳定性分析、离均差分析、聚类分析判定各品种稳产性和适应性及亲缘关系,并对试验点进行地点相似性分析。[结果]阜花系列花生新品种产量均高于对照或当地推广品种,阜花18号产量最高,稳产性、适应性最好,并将辽宁省花生主产区进行区域区划划分。[结论]阜花系列花生新品种适宜在辽宁省境内种植,不同地区宜选择不同的主栽品种。

[Objective] Yield, yield stability and adaptability region division of＂ I.iaoning peanut varieties were studied,which wouht provide theoretical basis for increasing peanut unit yield level. [Method] 8 varieties were used to test in 7 places in Liaoning province. Treatment yield were measured by variance analysis, stability analysis, standard difference analysis and cluster analysis, which were used to judge the yieht stability, adaptability and genetic relationship. Test sites were conducted by locations similarity analysis. [Result] The yield of new variety FuHua series were higher than check variety and local spreading varieties. FuHua No. 18 had the highest yield, yield stability and adaptability. The regionalization was divided in Liaoning province. [Conclusion] The FuHua series was suitable for planting in Liaoning province. Different regions shouht choose different main cuhivars.
