Abstract: Fengkelai is a new and distinct cultivar with storage-resistant and productive from the northern highbush blueberry. It was formerly known as the Senmao 353. Fengkelai was selected from sown seedlings of the blueberry variety Sunrise, which belongs to the genus Vaccinium L. in the family Ericaceae, and is a third-generation health-care berry fruit tree. This cultivar is suitable for the region north of the Yangtze River or high altitude areas in China, with high sweetness, delicate juice and high yield, good flavor with aroma, and suitable for the early-season fresh market. In July 2010, H. Wang collected the seeds of Sunrise from the blueberry germplasm resource nursery of Dalian Senmao Modern Agriculture Co. Ltd. (Xinshi Village, Huajia Street, Jinzhou New Zone, Dalian). The seeds were germinated in Spring 2011 and 236 seedlings were grown. These seedlings were later transferred to the experimental station of Dalian Pushilan Agricultural Technology Co., Ltd., in Spring 2012. (Shuangsheng Village, Changling Town, Zhuanghe City, Dalian, Liaoning Province) at a row spacing of 1.5 m with 2.0 m between plants. In late June 2015, G. Xu evaluated and selected the best progeny from them, numbered Senmao 353. After evaluation, the Blueberry of Senmao 353, with large fruit size, medium fruit density, erect sepal attachment position, flat round shape, medium blue color(102-B), good powder and uniform texture, small fruit picking scar, high sweetness, medium acid, good flavor and aroma, high firmness, good productivity, suitable for fresh fruit market. The ripening period in the natural state is around the second half of June, and it is an early-maturing variety. Fengkelai had medium thickness and uniform distribution of pollen, medium firmness of fruit (2.77 N), average single fruit size was 1.57 cm x 1.78 cm，and average maximum individual fruit weight was 2.34 g, with a maximum fruit weight of 2.57 g. From June 2016 to July 2017, the blueberry variety was thoroughly evaluated for key traits such as fruit yield and quality, and its specific traits were stable. The new blueberry variety passed the DUS on-site substantive examination and received a certificate of plant cultivar rights from the National Forestry and Prairie Bureau in 2019,and was named Fengkelai. and was named Funkelai. Fengkelai is an early ripening variety, the fruits usually start to ripen in late June in their natural state，and the range of requirement is about 600-1200 hours, which is suitable for planting in northern China or high altitude areas. Soil texture is preferred to charcoal soil, loamy soil or sandy loam, acidic soil, suitable range of soil pH is 4.0 to 5.5, and organic matter content is required to be 3.0% to 15%. Plant spacing is recommended to be 1.5m×2.0m, well-rotted organic fertilizer should be applied before planting seedlings. Insufficient water during fruit expansion can seriously affect tree growth, development and yield. Black mulch can be used to cover under the canopy of blueberry trees for effective weed control. Winter pruning and summer pruning should be carried out, pruning after the completion of the summer fruit harvest, pruning methods using a combination of short cutting and thinning way to carry out. Winter pruning in the white dew, pruning method to promote flower buds. The main blueberry diseases are leaf chlorosis, stiff fruit disease, and gray mold. Winter protection can be provided by burying the soil or utilizing wraps such as plastic or non-woven fabrics.
