The leaf is dark green and the leaf margin is spreading. Inflorescence peduncle yellowish green, Corolla white, stamens yellow, more pollen, weak fertility, stigma 3-divided, natural occasionally fruiting. The potato block is flat, round or oval, the skin is yellow and the flesh is white, the bud eye is shallow, there are depressions in the navel, the tubers are concentrated, there are 7 tubers per plant, and the rate of large and medium tubers is 75%. High resistance to virus disease, medium resistance to late blight and strong drought resistance. In the regional trial, the yield per mu was 1472.3 kg, 32.3% higher than that of the control.

Suitable range: suitable for planting in arid areas, cold, damp and Eryin areas, and suitable for early-maturing cultivation with plastic film mulching.

Key points of cultivation: the density is 4000mm / mu in cold, shady and humid areas and 2500m / mu in arid areas, and the density of plastic film cultivation can be increased appropriately. Implement plant selection and seed retention, and advocate the use of virus-free seed potato.
