Selection and evaluation of early spring fresh pepper varieties
In order to promote the early spring fresh pepper industry in Guizhou,a random block design was used for vari-ety comparison experiments with 36 introduced fresh pepper varieties as materials.By measuring the agronomic traits,dis-ease resistance,and yield of the different varieties,the fresh pepper varieties suitable for early spring planting in Guizhou province were screened.The results showed that 17 of the tested materials were early maturing varieties,among which Qianla 972 had the shortest initial harvest time(only 47 d).The disease incidence of Shiyanqingfeng was the lowest,only 1.28％.Yaoqianshu 616 had the highest yield(2 971.07 kg·667 m-2),which increased by 22.30％compared with the con-trol.The clustering analysis result indicated that 36 pepper varieties could be divided into 4 groups,with the third group having the highest yield.The comprehensive performance of Yaoqianshu 616,Qianla 956,Qianla 972,Qianla 991,and Meiluo was good,which was suitable for early spring planting in low altitude and heat-rich areas in southeast Guizhou.
