When cultivating, it is necessary to sow early in time, plough deep as soon as possible, and cover the soil before the first flower; 3500-4500 seedlings per mu; Suitable for interplanting with corn. Suitable for potato planting in the whole province.
2. Jin Shu 1 1: It was bred by Shanxi Alpine Research Institute and approved by Shanxi Province. The plant is erect with few branches, and its height is 70- 100 cm.
There are many flowers, 3-4 tubers per plant, and the tubers are concentrated, and the tubers are large and tidy. The potato is oblate, with yellow skin and light flesh, and moderate bud eye depth. The rate of sweet potato above100g is 8 1%. The starch content is 15.5%. Mid-late maturity varieties, from emergence to maturity about 1 10 days, are drought-resistant, disease-resistant and storable. Average yield per mu 1500 kg.
Apply sole fertilizer before sowing, concentrate on nest application, and conditionally water and fertilize in bud and flowering period; It is advisable to leave 4000 seedlings per mu; Pay attention to the prevention and treatment of bunchy top disease. Suitable for potato planting in the whole province.
3. Jinyin No.8: introduced from the Netherlands. The plant is erect, with a plant height of about 60 cm, purple stems, strong growth potential and few branches. Green leaves, medium hair, compound leaves, drooping, slightly wavy leaf margin, 3-5 pairs of lateral leaflets. Peduncle green, stamens orange. Tubers are oblong, round at the top, with yellowish skin, bright yellow meat, smooth skin, large and neat pieces, few and shallow bud eyes, concentrated tubers and rapid tuber expansion. Contains protein 1.55%, reducing sugar 0.03%, starch 12.4- 14%, vitamin C 13.6% mg/ 100g fresh potato. It takes about 60 days from emergence to maturity. Plants are susceptible to late blight, tuber disease, ring rot, YN and mosaic virus. The average yield per mu is about 1700 kg.
This variety is easy to be planted in close density when cultivated, and the suitable density is 4000-5000 plants. Water-resistant fertilizers and tubers are sensitive to light, so they should be cultivated as soon as possible, and the seeds in the second season should be germinated and dried.

Breeding unit: Alpine Institute of Shanxi Academy of Agricultural Sciences
Characteristics: Erect plant type, medium branching, green stems, light green leaves, white corolla, plant height of about 80 cm, medium natural fruit, oblate potato, light yellow flesh, medium bud eye depth and concentrated tubers, with 4-5 tubers per plant.
It takes about 105 days for mid-late maturing varieties from emergence to maturity. 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 is 2.7%, VC13.1mg/100g, starch 14.4%, dry matter is 22. 1%, and reducing sugar is 0.4%.
Yield performance: From 2000 to 20065438+0, we participated in the regional test of mid-late maturity potatoes in the whole province. At 8: 00 in 2000, the average yield per mu was 1453 kg, which was 32% higher than that of the control Jin Shu No.7, and the ratio of yield increase points reached 100%. At 200 1, the average yield per mu was 1089 kg at 8: 00, which was 30.4% higher than that of the control Jin Shu No.7, and the ratio of yield-increasing points reached 100%. In 2002, the average yield per mu was 1760.4 kg, which was 16.3% higher than that of the control Jin Shu 7.
Cultivation points: 3500 plants per mu. In plots with good water and fertilizer conditions, the planting density can be appropriately increased, and it is appropriate to sow about 4000 plants per mu. Because of the high productivity of this variety, if it is planted on high ridges, it can give full play to its high yield potential.
Suitable areas: it can be planted in potato planting areas such as Datong, Shuozhou, Xinzhou and Taiyuan in our province.
