Fruit Research Institute of China Academy of Agricultural Sciences was bred by crossing apple pear as female parent and valley pear as male parent. The average fruit weight is 280 grams, the fruit is nearly round, the skin is yellow-green, it turns yellow after storage, the fruit surface is smooth and waxy, and the fruit point is large and obvious. The stems are shallow, wide and wrinkled. Sepals persist, calyx is deep and wide, wrinkled and rusty. Small core, white meat, tender and crisp meat, rich juice, strong taste, sweet and sour. It contains soluble solids 12.0% ~ 15.7%, and its quality is extremely high. Fruits have strong storability, and can generally be preserved until April-May of the following year.
The crown is broad and conical, and the tree is upright. The plant has strong growth potential, high germination rate (73.7%) and strong branching ability, and more than three long branches grow under the incision. Young trees begin to bear fruit in the middle and early stage, and can bear fruit in 3 ~ 4 years after planting. The proportion of all kinds of fruiting branches of young trees is: long fruit branches 25%, middle fruit branches 10%, short fruit branches 33% and axillary flower buds 32%. Adult trees mainly bear short fruit branches. High yield, no fruit drop before harvest, and poor management are prone to large and small years. In Xingcheng, Liaoning Province, flower buds germinate in early April, bloom from late April to early May, fruit ripens from late September to early June 10, and fruit development period 142 days. Under the condition of rootstock cultivation, the row spacing and plant spacing can be 5 meters ×4 meters, which is suitable for evacuation layer trees; Dwarf rootstocks are densely planted, with row spacing of 4m× 2.5 ~ 3m, which can be small crown sparse layer or free spindle shape. This variety is too branched, so it should be cut less and dragged more, and the branches should be thinned properly. In the new year, we should get rid of long branches and buds to prevent the phenomenon of big and small years. The appearance of fruit is not very beautiful, which can be improved by bagging technology. Pollination varieties are Yali pear, Apple pear, Zaosu pear, Xuehua pear and dangshan pear. Strong cold resistance, resistance to scab, and fruit vulnerable to Toona sinensis.
