The middle and late maturing varieties are about 105 days from emergence to maturity. It has strong growth potential and strong drought resistance.

According to the quality analysis of the vegetable quality Supervision, Inspection and testing Center of the Ministry of Agriculture: crude protein 2.7% charge Vc13.1 mg par 100g, starch 14.4%, dry matter 22.1%, reducing sugar 0.4%.

Yield performance: participated in the regional test of the provincial potato mid-late maturity group from 2000 to 2001, the average yield per mu at 8 points in 2000 was 1453 kg, which was 32% higher than that of Jinshu 7, and the proportion of yield increase reached 100%. The average yield per mu at 8 points in 2001 was 1089 kg, 30.4% higher than that of Jinshu 7, and the proportion of yield increase reached 100%. In 2002, the provincial potato varieties in the middle and late maturity group were tested, and the average yield per mu was 1760.4 kg, which was 16.3% higher than that of the control Jinshu 7.
