15个樱桃番茄品种单株产量与主要农艺性状的灰色关联分析及综合评价
Grey correlation analysis and comprehensive evaluation of the yield per plant and main agronomic characters of 15 cherry tomato varieties
摘要
Abstract
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.关键词
