摘要
为了给高山高原地区青花菜的良种选育提供理论指导,运用灰色关联度分析法对14个青花菜新品种单株产量与表型性状进行分析。结果表明,青花菜单株产量与11个表型性状的关联度大小依次为:花球主茎横径>花球主茎高>叶片宽度>花球纵径>开展度>花球横径>株高>叶片长度>分枝数量>外叶数量>生育期。得出对单株产量的影响以花球主茎横径和花球主茎高最大,其关联度分别为0.7954和0.7595。根据各性状权重数据得到青花菜综合评价模型:H=0.0808Z_(1)+0.0904Z_(2)+0.0923Z_(3)+0.0835Z_(4)+0.0888Z_(5)+0.0954Z_(6)+0.0840Z_(7)+0.0936Z_(8)+0.0916Z9+0.0975Z_(10)+0.1021Z_(11),筛选出中青518、中青16、中青118和中青193可作为下一年当地试验示范推广品种。因此,在青花菜杂交育种过程中,以产量为育种目标,可注重花球主茎横径和花球主茎高2个性状的选择,同时兼顾其他性状进行综合筛选。
In order to provide theoretical guidance for the breeding of broccoli in the alpine plateau region,in this study,the yield per plant and phenotypic quantitative traits of 14 new varieties of broccoli were analyzed by grey correlation analysis.The results showed the correlation degree between yield per plant and 11 phenotypic quantitative traits of brocco-li was as follows:Center column width>Center column height>Leaf width>Flower head vertical diameter>Expan-sion degree>Flower head transverse diameter>Plant height>Leaf length>Branch number>Outer leaf number>Growth period.It was concluded that the width and height of the central column had the greatest influence on the yield per plant,and the correlation degrees were 0.7954 and 0.7595,respectively.According to the weight data of each trait,the comprehensive evaluation model of broccoli was obtained:H=0.0808Z_(1)+0.0904Z_(2)+0.0923Z_(3)+0.0835Z_(4)+0.0888Z_(5)+0.0954Z_(6)+0.0840Z_(7)+0.0936Z_(8)+0.0916Z9+0.0975Z_(10)+0.1021Z_(11).Four varieties were selected as Zhongqing 518,Zhongqing16,Zhongqing 118 and Zhongqing 193,which could be used as local test demonstration and promotion varieties.Therefore,in the process of hybrid breeding of broccoli,if the yield was breeding goal,the two traits of center column width and heigh could be paid attention,and comprehensively consider other traits for comprehensive screening.
