摘　　要：The new late-maturing pear cultivar‘Suyu’was bred through hybrid breeding using‘Mili’as the female parent and‘Dangshansuli’as the male parent.This cultivar has a nearly round fruit shape with a greenish-yellow skin,an average single fruit weight of 394.3 g,and a small core.The flesh is white,fine-textured,crisp,juicy,sweet,and aromatic,with a soluble solid content of 12.8%.The tree has a strong growth vigor,an open canopy,high budding rate,and strong branching ability,making it suitable for spindle or cylindrical cultivation.The main color of the one-year-old branches on the sunny side is brown.The young leaves are yellowish-green,and the mature leaves are ovate with sharp serrations.Each inflorescence has 5 to 7 flowers with pink petals,a pistil that protrudes above the stamens,and purple-red anthers.The fruit development period is about 150 d,and it matures in mid-to-late September in Changli,Hebei.The cultivar is high-yielding,stable,and well-suited for storage.‘Suyu’can be cultivated in pear-growing areas of Hebei Province and regions with similar ecological types.
