8 common appearance problems of bagged Emerald pear and their solutions
Emerald is an excellent new pear variety bred by the Zhengzhou Fruit Research Institute, developed by crossing New Century and Zaosu. Since 2000, after 6 years of bagged cultivation through top-grafting to change the canopy in our city, we have found that this variety has a regular fruit shape, a smooth and glossy fruit surface, creamy white flesh, a crisp and tender texture with abundant juice, and few stone cells, making it an early-maturing pear variety of excellent quality.

For this reason we conducted an investigation and analysis and proposed solutions.
