Under normal circumstances, the main varieties of sweet cherries are required to have a large fruit, deep color, anti-crack fruit, good flavor, resistance to storage and transportation and other characteristics, but in fact, any one species can not be perfect. The varieties with large meat hardness are generally good in storage and transport performance, but they often have severe cracking. The varieties with bright red and bright colors have high commodity value but are vulnerable to bird damage. The large varieties, though popular with the market, are vulnerable to Crushing injury. Therefore, when selecting varieties, first consider the main economic traits, and overcome the possible adverse traits by adopting a reasonable mix between varieties and using comprehensive cultivation management techniques. In addition, the ecological conditions in different regions are quite different, and the problems that may arise in production are not the same. When selecting varieties, we must also consider the local ecological environment conditions. First, maturity. According to the early and late ripening period, it can be divided into three types: early-maturing, medium-maturing, and late-maturing. For example, in the South Central and Eastern Shandong Province, the ripening period of early maturing varieties is generally not likely to occur after the rainy season. The fruit development period of medium-maturing varieties is 50-60 days, and that of late-maturing varieties is more than 60 days, and the longest can reach 80 days. At present, many early-maturing varieties are selected in production, but attention should be paid to the reasonable mix of early, middle and late varieties, and extend the supply period of fresh fruit. Second, the size of the fruit. Sweet cherry fruit weight is generally more than 5 grams, the maximum fruit weight up to 20 grams, most varieties of fruit weight in 9 ~ l1 grams. For small fruit sweet cherries, only big fruit can sell well, so when choosing a variety, fruit size is an important consideration. At present, the big fruit, red light, Brooks, Samita, Rennie, Binku, and friendship are all big fruit varieties. Third, anti-cracking fruit. In the production of sweet cherries, cracking is a very important factor affecting fruit quality. There is a certain difference in the crack resistance between varieties. Laizhou Zaohong, Sweetheart, Labins, Samita, Stanley and other varieties are varieties of anti-crack fruit. Brooks and Rennie are heavier. Fourth, color. Sweet cherry can be divided into purple, red and yellow according to color, or divided into dark and light colors. According to people's preferences and consumption habits, dark (red or purple) varieties are more competitive than light (yellow) varieties, and therefore, darker varieties should be the main products in production. Early fruit, red light, early morning, Santina, Pioneer, Sweetheart, Binku, Rabins, and Samith are all good dark varieties. However, some of the light-colored varieties have some good varieties with high yield, large fruit, hard meat, and good flavor, such as Satoko, Yantai No.1, etc., and no doubt it can also be used as a main cultivar. Fifth, high yield. Samita, Santina, Friendship, Rabins, Pioneer, Zhifu Red, Hongfeng, Renyi, Red Light and other varieties are relatively productive varieties in normal years. Six, fruit flavor. Sweet cherries are mainly sweet, with a strong sweet and sour taste. For the current variety, Sato jin has the best flavor, Brooks, Ruby Sweet, Early Fruit, Renée, Topaz, Binku, Rabbins, Pioneer. The flavors of friendship and friendship are also excellent. The red light flavor is light and the red honey is sweet.
