What kind of varieties does Katim belong to? is there any kind of domestic coffee grown in Yunnan?

Catimor: in 1959, the Portuguese mixed Brazilian Kaddura and Timo to develop a disease-resistant Katim / Katimo, which is now an important variety of commercial beans. Coffee is a short-day plant. Coffee has the characteristics of multiple flowering and concentrated florescence. The florescence of small seed coffee in Yunnan is from February to July, and the flowering period is from March to May. The flowering of coffee is greatly affected by climate, especially rainfall and temperature. Coffee flowers have a short life span of only 2-3 days. Small seed coffee usually opens at 3: 5 in the morning, and it takes a long time for the fruit to bloom from 5 to 7 in the morning. It takes 8 to 10 months for the fruit of small seed coffee to mature, usually from October to December of the year. Rainfall has a great influence on fruit development. Tibika, which has a direct impact on fruit, is an old variety of Arabica. It is well known that Kona in Hawaii and the Blue Mountains in Jamaica are also Tibika species. In the vast expanse of Katim, it is easy to recognize. After careful observation, you will find that each species has its own appearance, Katim's leaves are hanging down, the tree shape seems to be wearing a cloak. On the other hand, Tiebika has upward branches, and the tip of the tree, with new leaves on the copper top, shows that most of the plants in Yunnan are now Katim, which is a hybrid of Kaddura and Robusta, a branch of the bourbon line of Arabica species. The reason for planting this variety is that Katim has the Robusta gene, so it is better than a single old variety in disease resistance, and the yield is better than that of the delicate old variety. The yield of poor disease resistance is also low, farmers naturally prefer to grow Katim, so now Yunnan has set off a period of Katim style Katim beans are round and thick, Tiebika is thin and long, and Katim's central line is messy, under the same conditions, Tibika's quality is better than Katim, and the price is also on the high side.

The main results are as follows: 1. The state-owned Lujiang Farm in Baoshan City planted 12.6 mu in March 1991. The land is unshaded and irrigated once in the dry season. The average level of management and fertilization is above. In 1993, the average yield per mu was 75 kg in 1993, 350 kg in 1994, 225 kg in 1995, 217 kg per mu in three years, and 36% higher than Tiebika and Bobang (160 kg per mu).

2. Yunnan Dehong Tropical Agricultural Science Research Institute 1991 planted 30 mu with no shade and anhydrous irrigation, with a medium level of fertilization and management. the average yield per mu was 304.3 kg in 1993, 294 kg in 1994, 222.5 kg per mu in 1995, 273.6 kg per mu in three years, and 82% higher than S288 (S288 average yield per mu).

3. The covered field coffee base of Ning'er County Coffee Company planted 50 mu in July 1998, the site environment was unshaded, the level of management was medium, and the level of fertilization was low, but the soil fertility was high. Since 2000, the average yield per mu was 285 kg in 2001 and 2002, 340 kg in 2002, 293 kg in 2003 and 306 kg in 2003. The yield is 53% and 91% higher than that of PT (the average yield of PT is 200kg per mu and the average yield of P4 is 160kg per mu).
