The main producing areas of Japanese chestnut are Japan and North Korea. The branches and leaves are slightly red, the leaves are long and narrow, yellow-green. Chestnut bracts are thin and long, with thick skin and poor toughness, making it difficult to peel off. Chestnuts bear fruit early and are adapted to coastal, warmer and humid climates. Dandong chestnut in Liaoning Province of my country is a kind of Japanese chestnut with better quality and more cold tolerance; Korean chestnut distributed on the Korean Peninsula is a variant of Japanese chestnut; Wendeng chestnut in Shandong Province of my country belongs to Korean chestnut, which is more suitable for coastal environment. But the quality and cold tolerance are not as good as Dandong Li. The grafting affinity between Japanese chestnut and Chinese chestnut is generally poor.

2. European chestnut

European chestnuts are native to Southern Europe and West Asia, and are naturally distributed in Italy, France, Spain, Yugoslavia, Turkey and the Caucasus. The tree is tall, with thorns and nuts similar to Japanese chestnuts, and the astringent skin is not easy to peel off. It is suitable for the Mediterranean climate, has poor resistance to chestnut blight and ink disease, and is not suitable for cultivation in warm and humid areas.

The northern limit of its distribution is wider than that of Castanea henryi. Small tree, shaped like wild chestnut, but with smaller leaves, involucres, and nuts, with scaly glandular dots on the back of the leaves, thin involucres, and relatively slender spines. Nuts weigh 0.7 to 1 grams. Mao Li is not compatible with chestnut grafting and cannot be used as a rootstock for chestnut.

5. Castanea henryi

Shrubs and small trees have stellate hairs on the back of the leaves, but the leaves are smaller than chestnuts, and the fruit is smaller.
