| 摘 要： | 采用灰色系统理论中的品种灰色关联度多维综合评估分析法,对35个参试杂交种的9个主要性状指标进行了综合分析和评价,排出了各参试品种的优劣,旨在为鉴定和选育玉米新品种提供依据和方法。结果表明,玉米杂交种产量与其相关性状关联度大小顺序为:穗长>行粒数>千粒质量>穗行数>粒深>穗位高/株高>穗位高>株高>轴粗/穗粗;与产量密切相关的性状是穗长、行粒数、千粒质量、穗行数、粒深等。

| Abstract: | Applying the multidimensional comprehensive evaluation method about the grey correlation degree of the variety in the grey system theory,9 main traits of 35 tested hybrids were comprehensively evaluated and analyzed and the pros and cons of the tested varieties were listed to supply basis and method for the identification and breeding of new maize variety.The analysis result showed that the correlation degrees of the yields and correlated traits of the corn hybrids were in an order from big to small as:spike length>kernel number per row>1 000-grain weight>row number per ear>grain depth>ear position height/plant height>ear position height> plant height>axis/spike;The traits related to the yield were spike length,kernel number per row,1 000-grain weight,row number per ear,grain depth and so on. |
