摘　　要：为丰富太行山冷凉区樱桃番茄品种,提高农民种植效益,满足夏季人们对樱桃番茄的消费需求,对平山县太行山区引进的15个樱桃番茄品种进行植株性状和果实性状等测定,并对主要农艺性状作变异性、相关性和灰色关联分析。结果表明:15个樱桃番茄主要农艺性状变异系数最大的是单果重,其次为穗结果数,变异系数最小的是可溶性固形物含量;各性状间存在不同程度的相关性且绝大部分为显著或极显著相关;每个性状与单株产量存在不同程度关联,关联度排序为果实纵径>平均单果重>果实横径>叶宽>节间长度>平均穗结果数>茎粗>叶长>可溶性固形物含量>叶片数。综合评价发现,樱桃番茄品种‘绿翡翠’‘紫桃二号’‘中樱8号’表现较好,适宜太行山冷凉区种植推广。研究表明,应用灰色关联法对15个樱桃番茄品种的11个性状进行综合评价是可行的。本研究可为太行山冷凉区樱桃番茄优良品种的筛选提供参考,同时对越夏茬口番茄推广种植具有重要意义。Aims of this study were to enrich cherry tomato varieties in the cold area of Taihang Mountain,improve farmers’planting efficiency and meet consumers’demand for cherry tomato in summer.Fruit characters of 15 introduced cherry tomato varieties in Taihang Mountain of Pingshan County were measured,and the variability,correlation and grey correlation of main agronomic characters were analyzed.The results showed that the largest coefficient of variation among the main agronomic characters of the 15 cherry tomatoes was single fruit weight,followed by the grains number per spike,and the smallest coefficient of variation was soluble solid content.There are different degrees of correlation among the traits,and the majority of the traits displayed significant or extremely significant correlation;Each trait had different degree of correlation with yield per plant.The correlation between yield per plant and yield-related characters was ranked from high to low as follows:Longitudinal diameter,average fruit weight,transverse diameter of fruit,leaf width,internode length,average panicle number stem size,leaf length,soluble solid content and leaf number.The results of comprehensive evaluation showed that the cherry tomato varieties“Lvfeicui”,“Zitao No.2”and“Zhongying No.8”performed well and were suitable for planting and popularizing in the cool area of Taihang Mountain.In conclusion,it is feasible to comprehensively evaluate 11 characters of 15 cherry tomato varieties by grey correlation method.This study can provide reference for the selection of excellent varieties and breeding target of cherry tomato in the cold area of Taihang Mountain,and has important production significance for the popularization of crop tomato planting over summer.
