| 摘 要： | 应用灰色关联分析方法，对青海省旱地小麦品种的主要数量性状与产量之间的关联度进行了分析与排序。结果表明，关联度大小为公顷穗数〉穗长〉穗粒数〉千粒重〉公顷苗数〉株高。说明旱地小麦育种与栽培夺高产的主要手段在于有效地促进形成公顷穗数，穗长，穗粒数以及千粒重等因子。

| Abstract: | Correlativities between main characters and yield of spring wheat on Qinghai dryland were analysed by the Grey Correlativity Analysis (GCA).The result indicated that the order of grey correlativities was number of spike per hectare > spike length> number of grain per spike > 1000-grain weight > number of seedlings per hectare > plant height,which showed that main ways of spring wheat production and variety devolopment on Qinghai dryland to get high yield are to focus on the four yield factors such as the number of spike per hectare,spike length,number of grain per spike and 1000-grain weight. |
