Corvette (potato)
Variety source: formerly known as Calwhite, alias A76147-2, it was selected from the hybrid offspring of Pioneer × BC8370-4 in the United States. It was approved and approved for promotion by the University of California, the Idaho Experimental Station and the United States Department of Agriculture in 1997.
Characteristic plant type erect, strong, green stems and leaves, plant height about 70cm; Corolla is a medium-mature variety, about 8Od from emergence to maturity. The plant is resistant to internal and external infections such as growth crack, skin breakage, hollow and thermal necrosis, and is more resistant to late blight than Charlotte. The dormancy period is short. The yield is good, there are 4 to 5 tubers per plant, and the weight of tuber per plant is about 0.6kg. The rate of large and medium potatoes is more than 75%.
Output: average about per 667m22000kg.
Use: suitable for French fries and potato chips.
Breeders Agricultural Bureau of Weichang County, Hebei Province
The region and technology are suitable for the one-season planting areas in the north and northwest where the incidence of late blight is relatively mild.
The cultivation must choose the land with deep soil layer, medium fertility and good drainage and ventilation. Increase fertilizer input, achieve balanced fertilization of N, P, K, deep planting and high soil cultivation per 667m23500 plant, and pay attention to the prevention and control of late blight.

Scientific storage of potatoes
The stacking method selects a well-ventilated warehouse with a dry site, first fumigated with formalin and potassium permanganate, and then put potatoes into the warehouse, generally 750 kilograms per square meter, about 1.5 meters high, surrounded by crates, baskets or planks. Put a number of bamboo ventilators in the middle. This method is suitable for short-term storage and autumn potato storage. Ventilation storage method will be stacked potatoes in baskets, each basket of about 25 kilograms, stack height of 5 to 6 baskets is appropriate. In addition, it can be scattered in the library, with a height of 1.3 to 1. 5%.

Both of them can produce high yield by interplanting potato with insect-resistant cotton.
In recent years, the potato intercropping insect-resistant cotton model has been welcomed by the masses. According to the investigation, this model can not only achieve a high yield of cotton (90,100kg per mu of lint), but also "pick up" 1500kg and 2000kg of potatoes per mu. The main points of planting techniques are as follows. First, potato ① seed selection and sprouting. Virus-free varieties with early maturity, dwarfing and high yield, such as Holland No. 7 and Jinyin No. 8, should be selected with 80kg seed potato per mu. In mid-February, seed potato chips (40-50 pieces per kilogram) were cut into sunny beds or sheds.
