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.
