摘要
为助推贵州早春鲜食辣椒产业的发展,以引进的36个辣椒品种为材料,采用随机区组设计进行品比试验,通过测定不同品种的农艺性状、抗病性及产量等指标,筛选适宜贵州早春种植的鲜食辣椒品种.结果表明,参试的材料中17个为早熟品种,其中黔辣972始收期最短,仅为47 d;世研青峰发病率最低,仅为1.28％;摇钱树616校正产量最高,为2 971.07 kg·667 m-2,较对照增产22.30％.聚类分析结果表明,36个辣椒品种可划分为4个类群,其中第Ⅲ类群辣椒品种产量最高.摇钱树616、黔辣956、黔辣972、黔辣991及美螺等辣椒品种综合表现较好,适宜在贵州东南部低海拔富热区域早春种植.
Abstract
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.
