Evaluation of Vegetable Soybean Varieties Suitable for Intercropping with Fresh Corn in Guangxi

  • 摘要: 为促进广西鲜食大豆品种的引进、改良、选育和生产,采用鲜食玉米—鲜食大豆带状复合种植模式,对引进的8个鲜食大豆品种进行适应性综合评价。结果表明:所有品种均达到采摘标准,且能正常成熟收获种子;通过主成分分析,将8个品种的15个性状转换为4个相互独立的综合指标,累计贡献率为91.28%;各品种的因子得分和综合得分表明,综合得分大于0的品种依次为苏鲜豆22、上海青、苏鲜豆21号和南农46,因子得分表明浙鲜16和浙鲜19可作为早熟上市鲜食大豆品种推广。综合评价筛选出适宜在广西地区与鲜食玉米带状种植的鲜食大豆品种有苏鲜豆22、上海青、苏鲜豆21号、南农46、浙鲜16和浙鲜19,其中浙鲜16和浙鲜19可作为早熟上市品种种植。

     

    Abstract: In order to promote the introduction, improvement, breeding and production of vegetable soybean varieties in Guangxi, we evaluated the adaptability of eight vegetable soybean varieties in a strip intercropping with fresh corn. The results showed that all of the soybean varieties achieved the picking standards and could be harvested at maturity. Using principal component analysis, 15 traits of 8 varieties were converted into 4 independent comprehensive indexes, with a cumulative contribution rate of 91.28%. The scores of each variety showed that the comprehensive score of Suxiandou 22, Shanghaiqing, Suxiandou 21 and Nannong 46 were greater than 0, and the factor scores indicated that Zhexian 16 and Zhexian 19 could be introduced as early-maturing and marketing vegetable soybean. Moreover, the comprehensive evaluation results suggested that the vegetable soybean varieties Suxiandou 22, Shanghaiqing, Suxiandou 21, Nannong 46, Zhexian 16 and Zhexian 19 were suitable for the strip intercropping with fresh corn in Guangxi, and Zhexian 16 and Zhexian 19 could be planted as early maturing varieties.
