What is the best variety of Camellia oleifera?

There are excellent varieties of camellia sanhua. Three-flower Camellia oleifera is the general name of Asus, Huajin and Huaxin Camellia oleifera seedlings. It was cultivated by Professor Tan Xiaofeng of Central South University of Forestry and Technology for nearly 40 years. Camellia sanhua has high oil content and high yield. It is one of the varieties with the largest fruit and the highest yield approved by the state at present. Camellia oleifera is called super rice. Generally speaking, the fresh fruit weight of Camellia oleifera varieties is only 10g to 20g. The fresh fruit of camellia sanhua is stable at 45 ~ 80g, and the maximum single fruit 125g. During the high-yield period, the yield of fresh fruit per mu is more than 2000 kg.

1. Among them, there are mainly 14 varieties:

Changlin No.4, Changlin No.40 and Changlin No.53 were bred by Yalin Center of Chinese Academy of Forestry.

Ganwu No.2, Gan70, Ganxing No.48, Shi Gan No.84-8, Shi Gan No.83-4 and Gan8 were bred by Jiangxi Academy of Forestry.

GLS Ganzhou Oil 1, GLS Ganzhou Oil 2, GLS Ganzhou Oil 1, GLS Ganzhou Oil 5 and GLS Ganzhou Oil 7 selected by Ganzhou Forestry Bureau;

2. 1 1 mating varieties: Changlin No.3 and Changlin18 selected by Yalin Center of Chinese Academy of Forestry;

3. Take Jiangxi Province as an example: The 18 high-yield camellia oleifera varieties screened by Jiangxi Academy of Forestry passed the national certification: growth status (tree height, crown width, ground diameter, branching, growth status), economic characters (fruit setting rate, seed yield, oil content), stress resistance (insect resistance, drought resistance) and so on. Combined with the biological characteristics, pollen affinity and hybrid combination of varieties. Ganfu 20, Ganwu 1, Shi Gan 84-3 and Ganwu 12 were bred by Jiangxi Academy of Forestry. Ganzhou Forestry Bureau selected 4 kinds of GLS Ganzhou oil, 6 kinds of Ganzhou oil, 8 kinds of Ganzhou oil and 9 kinds of Ganzhou oil. Ganzhou petroleum 10.

4. The pilot project of high-yield clones of Camellia oleifera was approved by the state after the research on grafting and seedling raising of Camellia oleifera. This is a project jointly organized by Yalin College and Yalin Center. During this period, the model between Yalin Center and China Academy of Forestry is to cultivate this carefully selected camellia oleifera variety in subtropical areas. In the late 1970s, the state organized large-scale breeding and basically collected all the varieties registered by the Ministry of Forestry at that time. From 1980 to 1984, Yalin Center collected 293 camellia varieties distributed in more than ten provinces. 1990 after planting. We started to screen these 293 varieties, and it took five years to screen out 18 varieties. In recent years, we have been slowly screening these varieties by tail elimination method. We reported 9 national varieties. Changlin series will have the top five best varieties by 20 16 after passing the national certification.

5. The main cultivated varieties of Camellia oleifera Changlin series are Changlin 4, Changlin 40 and Changlin 53; Matching varieties are: Changlin No.3, Changlin18; These five varieties have been used for decades. In the process of cultivation, the yield is relatively stable, with high yield and high oil content. It has been preserved and is now widely used in this country.
