Sanhua oil tea varieties are excellent. Sanhua oil tea is the collective name of Huashuo, Huajin and Huaxin oil tea seedlings. It has been cultivated for nearly 40 years by the team of Prof. Tan Xiaofeng of Central South Forestry University of Science and Technology. Sanhua oil tea has a large amount of oil and high yield. It is one of the varieties with the largest fruit and highest yield approved by the state. It is known as the super rice of oil tea. Generally speaking, the fresh fruit weight of oil tea varieties is only 10g to 20g. Sanhua oil tea fresh fruit is stable at 45 to 80g, and the largest single fruit is 125g. Abundant production period of more than 2000 pounds of fresh fruit per mu.

1. There are 14 main varieties among them:

Changlin No. 4, Changlin No. 40, Changlin No. 53 selected by the Center for Subforestry of the Chinese Academy of Forestry;

Ganwu No. 2, Gan No. 70, Gan Xing No. 48, Gan No. 84-8, Gan No. 83-4, Gan No. 8 selected by the Jiangxi Academy of Forestry;

GLS selected by the Ganzhou Forestry Bureau Ganzhou Oil No. 1, GLS Ganzhou Oil No. 2, Ganzhou Oil No. 1, GLS Ganzhou Oil No. 5, GLS Ganzhou Oil No. 7;

2. 11 supporting varieties: Changlin No. 3 and Changlin No. 18 selected by the Center for Subforestry of the Chinese Academy of Forestry;

3. In Jiangxi Province, for example: 18 high-yielding varieties of oil tea screened by the Jiangxi Academy of Forestry have been certified by the state: the growth conditions (tree height, crown, diameter, branching, growth condition), economic traits (fruiting rate, seed yield, oil content) and resistance (resistance to pests and diseases, drought resistance), etc., combined with the biological characteristics of varieties, pollen affinity, hybrid combination test, Gan Wu series **** screened out the five main promotional varieties, respectively, Gan Wu No. 2, Gan Shi 84-8, Gan Xing 48, Gan Shi 83 -4, Gan 70, Gan No. 1, etc. Ganfu 20, Ganwu 1, Ganshi 84-3, Ganwu 12 were selected by Jiangxi Academy of Forestry; GLS Ganzhou oil 4, Ganzhou oil 6, Ganzhou oil 8, Ganzhou oil 9 were selected by Ganzhou Forestry Bureau. Ganzhou oil 10.

4. After the research of oil tea bud grafting, the state approved the pilot project of high yielding asexual lines of oil tea. It was a project jointly organized by Yalin Research Institute and Yalin Center. During this period, the model between the Yalin Center and the Chinese Academy of Forestry was to breed this carefully selected oil tea varieties in the subtropics.In the late 1970s, the State organized a large-scale selection and breeding of basically all the varieties registered by the Ministry of Forestry at that time. From 1980 to 1984, Yalin Center collected 293 oil tea varieties in the country, distributed in a dozen provinces. After planting in 1990. We started to screen these 293 varieties and it took 5 years to screen 18 varieties. During these years, we have been slowly screening these varieties using the tail elimination method. We reported 9 state varieties. With national certification, the Longwoods line will have the top five best varieties by 2016.

5. The main cultivars of oil tea Changlin series are: Changlin No. 4, Changlin No. 40, Changlin No. 53; the supporting varieties are: Changlin No. 3, Changlin No. 18; these five varieties have been used for decades. In the process of cultivation, the yield is relatively stable, high yield, high oil content, has been preserved, and is now popularized for use in the country.
