II. Variety selection principles In order to improve productivity, when selecting varieties, consideration should be given to selecting varieties that are suitable for cultivation purposes and local natural conditions. The selected varieties should also be the varieties that have been validated, recognized or recorded by the provincial departments or above, or the varieties that have performed well after local trial planting. For new varieties that have not yet been tried, they should be introduced in small quantities first, and then planted on a large scale after the comprehensive traits have been determined. Cultivars should be based on the market. First, it has the characteristics of consumer delight, good quality, large fruit, bright color; second, it has the characteristics of storage and transportation resistance
