Lushu 3, also known as Yanshu 13, was selected from the progeny of Xushu 18x American red hybrid in 1978 by Yantai Agricultural Science Research Institute of Shandong Province, the original line numbers 79mur555 and 79Mu709. Approved and popularized by Shandong crop Variety approval Committee in 1989.

Characteristics: top leaf green, aboveground stems and leaves are green, leaf tip heart-shaped, leaf larger, petiole length 21 cm, stem tip hairy, stem diameter 7 mm; medium vine type, longest vine length 213 cm, base branches 10; potato skin purplish red, potato flesh white, potato piece spindle-shaped Potato has good sprouting ability, large number of seedlings, sturdy seedlings, quick seedling return after planting, early ridge sealing, strong field growth, rapid weight gain of vine leaves, large t / r value, rapid expansion of potato in the later stage, resistance to a variety of diseases, namely, resistance to stem nematode, root rot, black spot, root knot nematode, strong drought and barren resistance, adaptation to mountain growth, but poor tolerance to waterlogging. The drying rate of potato pieces is 25.9%, the starch content of dried potato is 63.39%, the soluble sugar is 7.82%, the crude protein is 4.78%, the crude fiber is 4.28%, and the crude protein content of stems and leaves is 10.89% and 26.02%, respectively. Distribution area and utilization value: this variety is mainly distributed in Yantai of Shandong Province, Luoyang of Henan Province and Lulong of Hebei Province. It is suitable for planting in the land damaged by various diseases at the same time, and the yield is increased significantly. In addition, the yield of stem and leaf of this variety is high, which is 57.0% higher than that of Xushu 18, the protein content of stem and leaf is higher, the weight of stem and leaf increases quickly, and it has feeding value.

Cultivation characteristics: it is suitable for planting in the field where one or more diseases occur at the same time in the hills. the method of promoting germination at high temperature should be adopted to facilitate early sprouting and more seedlings.
