Introduction and Yield Charactertics Analysis of Fifteen Strawberry Varieties in Zhengzhou

Taking 15 introduced strawberry varieties as test materials, the plant growth, fruit quality, yield and disease resistance of 15 strawberry varieties were studied by using the single ridge and double row planting method in plastic greenhouses.The agronomic characters related to the yield of a single plant were analyzed by grey correlation analysis, and the strawberry varieties suitable for cultivation in Zhengzhou were screened out, in order to provide reference for grass research to enrich the strawberry variety structure and promote new varieties in Zhengzhou. The results showed that the strawberry varieties ‘Tianchali’‘Ganlu’‘Ningyu’ and ‘Shandong 2’ were suitable for cultivation in Zhengzhou.The order of the effects of the six agronomic traits on the yield per plant was inflorescence number＞average fruit weight＞leaf number＞leaf area＞plant height＞crown width.The number of inflorescences had the greatest effect on the yield per plant, followed by the average fruit weight.It showed that the number of inflorescences and average fruit weight were important agronomic characters in strawberry introduction and breeding.
