1. Huafeng Chestnut: A new variety bred by the Shandong Provincial Fruit Research Institute from the hybrid offspring of Yeza 12 (Wild Chestnut × Chestnut) × Chestnut. The crown of the tree is relatively open and round-headed. The involucre is oval and weighs about 40g. It contains an average of 2.9 nuts. The weight of a single kernel is about 8g. The yield rate is 56%. Ripe in mid-September. The nuts are neatly sized and beautiful, with fine, glutinous and sweet flesh, containing 46.92% water, 19.66% sugar, 42.29% starch, 3.33% fat and 8.5% protein. The saplings grow vigorously and female flowers are easily formed. The 1-2 year old seedlings are grafted in the same year after planting and will bear fruit the following year. The average is 2674.5kg per hectare in 2-4 years after grafting, 6405kg in the 7th year, and 4650kg in the 3-7th year on average.

2. Huaguang chestnut: bred by Shandong Provincial Fruit Research Institute with wild 12 × chestnut crosses. The crown of the tree is round-headed. The involucre is oval and weighs 43g. It contains nearly 3 nuts on average. The average single kernel weight is 8.2g. The fruit yield rate is 55%. Ripe in mid-September. The nuts are neat in size and bright, with fine, glutinous and sweet pulp, containing 45.73% water, 20.1% sugar, 48.95% starch, 3.35% fat, and 8% protein. Suitable for stir-frying and durable for storage. The saplings grow vigorously, and after a large number of fruits, the growth slows down, the fruiting branches are thick, the female flowers are easily formed, the fruits are early, and the yield is high and stable. The average yield per hectare is 2506kg in the 3rd year after seedling grafting, 5055kg in the 7th year, and 4080kg in the 3rd to 7th year.

3. Hongli No. 1 chestnut: Selected by the Shandong Provincial Fruit Research Institute from the hybrids of Hongli × Tai'an Bohui, the young leaves, branch buds and involucres have purple-red traits. The involucre is reddish brown, oval, and the single bract weighs 56g. Each contains 2.9 nuts, the single kernel weighs 9.4g, and the fruiting rate is 48%. Ripe around September 20th. The nuts are neat in size, plump and bright, with yellow flesh, fine texture, sweet taste, containing 54% water, 31% sugar, 51% starch and 2.7% fat. After being stored in sand for 5 months at room temperature, the corruption rate is only 2%. The tree is strong and strong, with easy female flower formation and early fruit and high yield. The average plant yield in 2-4 years after grafting is 8.2kg, the yield in 666.7m2 is 421.6kg, and the maximum is 560kg. It has a wide adaptability range and strong stress resistance. It can be cultivated in mountainous areas, hills and river floodplains. The tree body grows and develops well and the results are normal.

4. Huangpeng chestnut: In the sapling stage, it grows upright and vigorously, with long and strong new shoots. After a large number of fruits, it opens into a heart-shaped shape. Branches gray green. The lenticels are medium-large, oblong, white, and dense. Mixed buds are large, plump, and nearly round. The leaves are oblong, dark green, oblique and flat, with sharp tips and yellow-green petioles. The involucre is oval, with a single bract mass of 50-80 g. The involucre is thin (0.17 cm), rarely cracks when mature, and the fruit stalk is thick and short. The nuts are nearly round, dark brown, bright and beautiful, plump and neat. The base is small, crescent-shaped, and the weight of a single kernel is 11 g. The pulp is yellow, fine and sweet, with a water content of 51.37%. The dry sample contains 57.35% starch, 27.25% sugar, and 7.67% protein. Fat content is 1.78%, and the astringent skin is easy to peel off. It is durable in storage and has good commercial properties. During the fruiting stage, the tree height is about 4.3 m, and the trunk circumference is about 60 cm. The projected area of ??the tree crown is 20.24 m. . In Tai'an, it sprouts in early April, blooms in early June, and matures in early September. Female flowers are easy to form, the fruiting period is early, and the yield is strong. The average number of fruiting branches produced by the mother branches is 2.1, and the average number of fruiting branches is 3.1 involucres. Each bud contains 2.9 nuts, and the fruits are produced. The rate is over 50%. The saplings will bear fruit in the second year after grafting, and the yield of 4 to 5-year-old trees can reach 4 500 kg/hm.
