Comparative analysis and comprehensive evaluation of cowpea varieties in Hainan
In order to promote the development of cowpea industry in Hainan province and select suitable varieties for open field cultivation in summer,main agronomic traits,yield and quality traits and disease resistance of 13 cowpea varieties were analyzed.A comprehensive evaluation was conducted through principal component and clustering analysis.The results showed that Lüfeng 3000,Rejiang 1 and Hongyun 708 had the higher yield,Lvfeng 3000 was the highest with a yield of 1 380.48 kg·667 m-2;Lüfeng 3000 had the highest vitamin C content,with a concentration of 23.61 mg·100 g-1;Huabao 2 had the highest soluble sugar content,with a concentration of 25.37 mg·g-1;Super Haiyawang had the highest soluble protein and dry matter content,with a concentration of 2.43％and 10.02％,respectively;Rejiang 1 had the highest crude fiber content,with a concentration of 6.96％.Huabao 2 and Huagan·Manpengjin had the best resistance to rust,the disease index is 33.41 and 33.33,respectively.18 cowpea traits were converted into 6 principal components,and the highest score was Rejiang 1.The 13 cowpea varieties were divided into 3 groups by cluster analysis.Group Ⅰ had good rust resis-tance,group Ⅱ had highest yield,group Ⅲ had small pod and lowest yield.In summary,the varieties with good compre-hensive performance,such as Rejiang 1,Lüfeng 3000 and Xiangyan Hailongwang F,were selected through screening and evaluation,were suitable for large-scale promotion and cultivation in summer open fields in Hainan region.
