摘　　要：为准确评价不同茶树品种在重庆地区栽培种植的适应性,文章以福鼎大白茶为对照,对中茶112、TRI25、TR123等16个茶树品种在重庆地区的茶苗成活率、物候期、发芽密度、产量、抗性等性状指标进行比较分析,采用主成分分析法对茶树品种适应性进行综合性评价。主成分分析前3个主成分的累计方差贡献率达到82.576%,利用3个主成分的方差贡献率构建适应性综合评价模型,结果表明浙农901、中茶112、TRI25、TRI23、中选10号、浙农902、保靖黄金茶、川农黄芽早、玉笋、川沐28、马边绿1号、青心1号等12个茶树品种在重庆茶区适应性表现优于福鼎大白茶,适宜在重庆及相似茶区栽培种植,其中浙农901、中茶112、TRI25、TRI23、中选10号是供试品种中最适宜在重庆茶区种植的5个茶树品种,推荐在重庆及西南茶区推广应用。In order to accurately evaluate the adaptability of different tea cultivars in Chongqing area,tea seedlings of 16 tea cultivars including‘Zhongcha 112’‘TRI25’‘TR123’and‘Fuding dabaicha’were introduced in Chongqing to evaluate the survival rate,phenological stage,germination density,yield,resistance and other traits.The adaptability of tea cultivars was comprehensively evaluated using principal component analysis.The cumulative variance contribution rate of the top three principal components in the principal component analysis reached 82.576%,and the adaptive comprehensive evaluation model was constructed using the variance contribution rate of the principal components.Twelve tea cultivars including‘Zhenong 902’‘Baojing Golden Tea’‘Chuannong Huangyazao’‘Yusun’‘Chuanmu 28’‘Mabianlü 1’and‘Qingxin 1’had better adaptabilities than‘Fuding Dabaicha’in Chongqing tea area.So they are suitable for cultivation in Chongqing and similar tea areas.Among them,‘Zhenong 901’‘Zhongcha 112’‘TRI25’‘TRI23’,and‘Zhongxuan 10’are the five most suitable tea cultivars in Chongqing tea areas.This study provided a foundation for tea promotion and application in Chongqing and Southwest China.
