What kind of variety is Chaobai potato?

Characteristics: Short growing period, about 60 days from emergence to maturity. The plants grow luxuriantly with strong vigor, moderate plant height averaging about 40cm, and thick stems. Leaves are large, flat and spreading, with a deep green color. Flowers are white, and the virus disease degeneration index averages 2.23-9.97%. Tuber set is concentrated, tubers are round with white skin and white flesh, large and uniform, with the large and medium tuber rate averaging 71.0-73.7%, smooth skin, and relatively good quality, with starch content of 12.54-13.39% and crude protein content of 1.78%.

Cultivation points: Pre-sprout seed potatoes, sow early at the proper time, maintain 5000 plants per mu, apply heavy high-quality decomposed base fertilizer, strengthen management with timely irrigation, and harvest at the proper time. The seed retention method in northern regions is the same as the general seed retention method; in southern degeneration areas, it is best to retain seeds through cold storage and summer sowing or spring propagation and summer sowing. Because this variety degenerates lightly and slowly, using spring potatoes for seed retention with strengthened storage management can also achieve satisfactory yields.

Trial and demonstration situation: "Chaobai" potato showed increased yield compared with the control in breeding trials at all levels. In larger-scale trial plantings in the three northeastern provinces and Inner Mongolia and other places, the average yield per mu was 2150kg, with the highest reaching over 4000kg. This variety can be cultivated in all regions. The annual seed production volume is about 3 million jin, and the planting area can reach about 150,000 mu.
