Sunshine cherry and Rubins cherry are sister lines, which are medium-mature and high-yield varieties bred from Xianfeng and Stella by Canadian Summer Agricultural Research Institute on 1965. The fruit of Sunshine Cherry is round, with an average single fruit weight of about 13g. The fruit is large, with dark red skin and luster, sweet and juicy pulp, low acidity, soft texture and excellent quality. This variety has the advantages of high and stable yield, storage and transportation resistance, fruit cracking resistance, disease resistance and cold resistance. It can be grafted with gisela dwarfing rootstock for dwarfing and close planting, with early fruiting, strong adaptability to soil and high economic value. Rabins, the fruit is wide heart-shaped or nearly round, with a diameter of 2.28cm to 2.30cm, with a deep depression and a depression at the top. The fruit is bright red to dark red, bright and shiny, with thick and tough skin. The red flesh is crisp and juicy, with a single fruit weight of 8.6g and a thick and medium-long stalk.

Sunny cherry seedlings and young trees thrive. They bloom in Tai 'an, Shandong Province in early April, and the flowering period is about 8 days. They are self-pollinated, with high and stable yield, concentrated fruit ripening, short harvest period and low chilling requirement. They shed their leaves in 165438+ 10, and the annual vegetative growth period is about 220 days. Rabin tree has moderate potential, large crown, high germination rate, strong branches and short branches. It mainly bears bouquets, with a large amount of pollen, good pollination affinity with other varieties, good early fruiting and high yield. If cultivated in greenhouse, the growth potential is consistent, and there is no phenomenon of fruit bearing in different years. It blooms from early February to mid-February every year and matures in mid-April. This is a medium-mature variety.
