Abstract:
Taking 20 genotypes of Europe-type germplasm as experimental materials,the effect of natural high temperature (36.6/23.8℃) in the field conditions on the changes in the 11 indicators of seedling height,leaf area,stem diameter,stem number of female flowers,fruit number,heat injury index were studied.The heat tolerance on Europe-type cucumber of different genotypes were comprehensively evaluated,and system clustering analysis was used to screen and the species of cucumber was classified.The objective of this study was to breeding the heat tolerance of Europe-type cucumber of different genotypes,which would provide a theoretical basis for extension and evaluation on heat tolerance of Europe-type cucumber varieties.The results showed that the heat tolerance had significant differences among various materials.Four materials were heat tolerance and three materials were heat sensitive,according to the result from subodinate fuction analysis and hierarchical cluster analysis.This found will enrich heat tolerance materials in Europe-type cucumber,and promote the development of crossbreeding study.
