| 摘 要： | 目的]新疆属于大陆性气候,绿洲灌溉农业,目前大豆种植面积逐年扩大,单产逐年提高,发展新疆大豆生产极为重要.大豆产量性状是由株高、主茎节数、单株荚数、单株粒数、百粒重等多个性状构成.同时产量性状又是一个综合性状,受株高、主茎节数、单株荚数、单株粒数、百粒重等诸多因素影响.研究新疆大豆主栽品种产量与主要产量性状关系,为新疆大豆新品种选育、品种改良提供参考指标.方法]通过在新疆北部种植的8个主栽品种2010年在石河子地区的种植结果进行灰色关联分析.结果]应用灰色系统理论对新疆北部8个主栽品种产量与产量性状进行综合分析.结论]大豆产量与主要产量性状的关联度由大到小排序,次序为:百粒重＞单株粒数＞主茎节数＞单株荚数＞株高.该结果对大豆育种目标的制定、品种改良具有实际意义.

| Abstract: | 【Objective】Xinjiang has a continental climate and irrigated oasis agriculture.Soybean sowing acreage has been expanded year by year,so its yield gradually increased.No doubt,the development of soybean production in Xinjiang is becoming more and more important.Soybean yield traits are dependant on plant height,stem section number,pod number per plant,grains per plant,grain weight and other forms.At the same time,yield is also a composite character,decided by plant height,stem section number,pod number per plant,grains per plant,kernel weight,and many other factors.This paper aims to study the correlation between the yield of the main soybean cultivars and their yield traits so as to provide a reference index for breeding or improving new varieties in Xinjiang.【Method】Gray correlation analysis of eight cultivars planted in 2010 in Shihezi area,Northern Xinjiang was conducted in this paper.【Conclusion】Soybean production yield traits associated with major degrees from high to low is shown as follows: kernel weight> plant grains> stem section number> number of pods per plant> plant height.The result has practical significance for setting the goals of breeding or improving soybean varieties. |
