Grapes in greenhouse under the condition of protected cultivation grow healthily, the spike shape is neat, the fruit size is consistent, and the color and quality are obviously improved. In order to grow grapes efficiently in greenhouse, it is necessary to choose varieties reasonably according to local conditions. Based on many years' experience in grape planting and technical management, several early-maturing grape varieties with high economic benefits, strong disease resistance and convenient management were introduced:

It is the most early-maturing grape variety at present. After trial planting, it has the advantages of early maturity, large fruit and high yield. Under good management, the yield per mu can reach about 8000 Jin, with strong disease resistance and adaptability. It can be planted in northern and southern areas of China, which is suitable for greenhouse cultivation. Because of its early maturity, good taste, convenient management and great economic benefits, it is an ideal development variety for growers.
