| 针对宁夏南部山区落后的生产条件及特殊的气候生态类型，于2019年采用随机区组设计，结合一年多点的统计方法及系统聚类分析法，对选育的16个材料适应性、丰产性及抗逆性进行鉴定，以筛选出特征特性良好、丰产性状突出、适合宁夏南部雨养条件下不同生态区域的旱地冬小麦品种（系）。结果表明，‘9924’、‘Z0231-3-1’、‘Z0228-2-2’、‘长5385-1-2’、‘陇鉴103’和‘陇中1号’在原州区中河乡高坡村（E1）与彭阳县玉洼村（E2）两点同时增产，其中‘9924’、‘Z0231-3-1’、‘Z0228-2-2’、‘长5385-1-2’和‘陇鉴103’增产幅度大于10%；‘沧2007-1-1-1-1’在E1、E2两点同时减产，减产率分别为10.42%、11.24%；‘陇育0825’、‘Z0229-4-3’、‘Z0309-18-2’和‘Z0230-2’四份材料在E1增产，分别增产10.90%、9.94%、2.52%和5.39%，同时在E2减产，分别减产10.65%、14.20%、13.61%和17.16%；‘NB96022’、‘陇鉴107’、‘长5385-1’和‘2007-1-113’等4份材料在E1减产，分别减产15.81%、0.48%、20.84%和1.80%，同时在E2增产，分别增产12.43%、18.93%、18.34%和15.98%。通过聚类分析，将16个品种（系）分为4大类。5个品种（系）在两个试验点适应性好（很好），1个品系在两点适应性较好，其他在E1、E2点都表现一般或较差。综上可知，E1和E2点环境差异明显，在两点选育的同时增产的品种广适性具有一定代表性。但同时应看到，品种间、品种与地点间互作均不显著，也就是说，参试材料中缺乏产量较突出的基因型，也缺乏具有特殊环境适应性的基因型。 |

| In view of the backward production conditions and special climate ecological types in the southern mountain area of Ningxia, the adaptability, high\|yield, and stress\|resistance of 16 cultivars were identified by statistical method and systematic clustering method.The dry land winter wheat varieties (lines) with good characteristics and outstanding high\|yield characters were selected, which were suitable for different ecological regions under rain\|fed conditions in the southern Ningxia. The results showed that, the yield of ‘9924’,‘Z0231-3-1’,‘Z0228-2-2’,‘Chang5385-1-2’,‘Longjian103’ and ‘Longzhong1’ increased inboth testing sites of Zhonghe (E1) in Yuanzhou District and Yuwa (E2) in Pengyang County. Of which, five of them including ‘9924’,‘Z0231-3-1’,‘Z0228-2-2’,‘Chang5385-1-2’ and‘Longjian103’, their yield increased by more than 10%. The yield of ‘Cang2007-1-1-1-1’ decreased in the two testing sites by 10.42% and 11.24%, respectively. ‘Longyu 0825’,‘Z0229-4-3’,‘Z0309-18-2’and‘Z0230-2’ increased in E1 by 10.90%、9.94%、2.52% and 5.39%, and decreased in E2 by 12.43%、18.93%、18.34%和15.98%,respectively. By cluster analysis, 16 varieties (lines) were grouped into 4 categories. Of which, 5 varieties (lines) had good or very good adaptability, 1 varieties (line) had better adaptability, and the rest showed average or poor adaptability in the two testing sites. In summary, the differences of the environmental between E1 and E2 were obvious, and the wide adaptability of varieties with simultaneous yield increase between the two points was representative. But at the same time, it should be noted that the interaction between varieties and locations was not significant. That is to say, there was a lack of genotypes with outstanding yield and special environmental adaptability in the tested materials. |
