Where is the place of origin of Kyoho grapes? A roundup of the latest growing region information

The place of origin of Kyoho grapes is Japan. It is a mid-season tetraploid European-American hybrid. In 1937, Yasushi Oiue crossed Ishihara Wase as the female parent and Centennial as the male parent to breed it. It was introduced to China in 1959 and promoted on a large scale across the country, becoming a main variety deeply welcomed by fruit growers.

The water requirements for the growth of Kyoho grapes involve different requirements in humidity management: from bud break to before flowering, the relative humidity should preferably be controlled at 70%-80%; during the flowering period, relatively dry conditions are required, which is favorable for anther opening and pollen dispersal. However, excessive drought can easily cause the abnormal phenomenon of the corolla not cracking and falling off but drying up on the pistil, affecting fruit set.
