Main characters: plant type development, medium branch number, plant height about 60cm, stem green with purple base, strong growth potential; leaves green, medium hair into compound leaves, 4~5 pairs of lateral leaflets, medium arrangement density; flowers

Variety source: the Democratic Republic of Germany uses "Capella" as the female parent and "B.R.A.9089" as the male parent. It was bred in 1952 and introduced into China in 1956. Up to now, it is still one of the main varieties in Enshi area and southwest mountain area of Hubei Province.

Main characters: plant type development, medium number of branches, plant height about 60cm, stem green base purplish, strong growth potential; green leaves, medium velvet into compound leaves, 4-5 pairs of lateral leaflets, dense and medium arrangement; inflorescence total peduncle green, petiole node colorless, Corolla white, medium size, no double petals, stamens orange, stigma 3-lobed, natural fruit weak; paddle green, small, with seeds. The tuber has long tube shape, yellow skin, smooth epidermis, but rough top, more bud eyes, medium depth, medium tuber size, scattered tuber, long dormant period and storage resistance. Mid-late maturity, growth days of about 115d; excellent steaming quality; processing quality: 25.6% of dry matter, 17.5% of starch, 0.25% of reducing sugar, 1.1% of crude protein, vitamin C10.4 mg/100g; resistant to late blight; high resistance to cancer, not resistant to powdery scab, light to leaf roll and mosaic virus; generally 667 square meters of output is 1000~1500kg.

Suitable for planting areas: this variety is suitable for planting in mountainous areas in the southwest where there is a long frost-free period, heavy rain and humidity, and late blight is easy to be prevalent; it is mainly distributed in Hubei, Guizhou, Sichuan, Yunnan and other places.

Key points of cultivation techniques: this variety is tolerant to fertilizer, attention should be paid to the application of fertilizer during cultivation, and row spacing should be appropriately relaxed when interplanting with corn in order to reduce the shade of corn. For example, the row spacing of 95cm can be used for single intercropping, and 166cm can be used for double-row intercropping. The suitable density of single cropping is about 3500 plants per 667m2.
