摘要
为筛选出适合宁夏南部雨养条件下推广种植的旱地冬小麦品种,利用灰色系统理论关联分析法对在宁南山区选育的17个耐寒耐旱冬小麦品种比较试验材料结果进行了分析.结果表明,冬小麦产量性状与产量的关联度由大到小依次为千粒重、公顷穗数、株高、穗粒数、穗长.在参试品种中,产量性状对冬小麦产量的综合影响从高到低排前5的冬小麦品种为长5385-1、陇鉴103、X0309-15、陇鉴107、宁冬16号.综上所述,冬小麦产量受千粒重和公顷穗数影响最高,且长5385-1、陇鉴103、X0309-15、陇鉴107、宁冬16 号5 个冬小麦品在试验中综合表现突出,这为宁南山区选育推广理想的冬小麦品种提供了理论依据.
Abstract
In order to select the dryland winter wheat varieties suitable for the promotion of rain-fed planting in southern Ningxia,this study analyzed the comparative test results of 17 cold-resistant and drought-resistant winter wheat varieties breeded in the mountainous area of southern Ningxia by using the grey system theory association analysis method.The results showed that the correlation between winter wheat yield and yield was in the order of 1 000-grain weight,hectare panicle number,plant height,grain number per panicle and panicle length.Among the tested varieties,the top 5 winter wheat varieties from high to low were Chang 5385-1,Longjian 103,X0309-15,Longjian 107 and Ningdong 16 in terms of comprehensive effects of yield traits on winter wheat yield.In summary,the yield of winter wheat was most affected by thousand-grain weight and panicle number per hectare,and the five winter wheat varieties Chang 5385-1,Longjian 103,X0309-15,Longjian 107 and Ningdong 16 had the most outstanding comprehensive performance in the experiment,which provided a theoretical basis for the breeding and promotion of ideal winter wheat varieties in the mountainous areas of southern Ningxia.
