The development of cherries is to track the international frontier, and the cherry breeding goals are set very high: multi-ripening period, large fruit type, resistant to storage and transportation, good flavor, strong resistance to stress, greenhouse open space, self-flowering and fruiting, abundant yield, etc. To meet these requirements, the choice of hybrid parents is crucial. According to these characteristics, it came into being the exquisite crisp cherry sapling introduced in this article
"Exquisite crisp" cherry is the descendant of the American variety "Rennie", "Rennie" flesh is soft, astringent taste, bitter taste, late ripening, tree potential does not resist low temperature, with its mother after natural hybridization, the natural pollination of the "Rennie" species through embryo rescue, after 17 years of cultivation and breeding, showing a hard meat, sweet taste, no bitterness, early ripening, low temperature resistance and other gratifying changes, and the color of yellow with red halo, becoming an outstanding representative of colored sweet cherries. Exquisite crisp, broad heart type of fruit, single fruit weight 9.5-13.5 grams, soluble solid content of 20.5%, pure and sweet taste, light yellow flesh, crisp flesh, thick and juicy, in a place with sufficient light, the fruit surface coloring can reach more than 90% red, the skin is thick and resistant to storage and transportation, 0-4 °C can be stored for more than 60 days. The development period is about 55 days, and it matures about 7 days later than the red light. The tree is robust and resistant to low temperatures, and the mixed fruit of flower clusters and short fruit branches maintains the early abundance of Rennie.
Several excellent yellow varieties of hard fruits in China, Lu Ying No. 5 (1-5), hard fruit Jia Hong, Red Nanyang, Honey Crisp, American Big Red and other ripening periods are slightly late, and the ripening period of Linglong Crisp covers the late red light to the early American early stage, with its pure sweet taste and hardness, filling the blank of the excellent hard fruit yellow cherry of medium and early ripening.
