Ganping citrus originated in Japan. It is a hybrid product of Xizhixiang and Ponkan, which was introduced to China on 20 10. Ganping is a large-fruit citrus with a maturity of about 1-3 months, belonging to a late-maturing citrus variety. The fruit is flat and large, with a single fruit weight of 240g, a transverse diameter of 8.8cm and a longitudinal diameter of 5.7cm. Generally, oil cells are different in size and have dense protrusions. There are 6-8 short radial grooves in the fruit stalk, and the petals of the capsule are 8- 1 1 petal.

First, the source of varieties

1. Ganping citrus mainly comes from Japan. It is a new citrus variety which is a hybrid of Xizhixiang and Ponkan. 20 10 was introduced to China.

2. Ganping, Japan, is a large-fruit citrus with a maturity of 65438+ 10-3 months, which belongs to a late-maturing citrus variety.

3. Ganping's pulp is very textured, with strong citrus flavor, full pulp, thin skin, tender taste and residue, high sugar and low acid, belonging to high-grade citrus varieties.

Second, the fruit shape

1. The fruit of Ganping Citrus is very flat and large, with a single fruit weight of 240g, a transverse diameter of 8.8cm, a longitudinal diameter of 5.7cm and a fruit shape index of 0.64.

2. The peel of Ganping fruit is orange-red, only 0.20cm thin, without white cortex and easy to peel. The fruit surface is smooth, the oil cells are mixed and the processes are dense.

3. There are 6-8 short radial grooves on the fruit stalk, and the petals are 8- 1 1, which is easy to crack internally, so that the pulp is tender and deslagging, and the juice is sweet and delicious, with excellent quality and sweetness 12 degrees.

4. The strong spring shoots and summer shoots of young and early trees with high turnover rate have strong uprightness, few branches and long branches, which are not easy to form flower buds. The fruit-setting rate of strong leafy branches of inflorescence is the highest, while that of multi-leafy single-flowered branches is lower, and that of horizontal branches and weak branches is lower.

Third, variety defects.

1. Although Ganping citrus is high-end and has good quality, there are still some shortcomings in this variety itself.

This variety has serious fruit cracking and thin skin, which is its advantage, but also its disadvantage. Ganping's thin skin will make it particularly easy to crack, which is the biggest variety defect of Ganping.

3. The maturity of Ganping citrus is in the middle of1-February, and the temperature is relatively low during the wintering period. If it is not planted in facilities, low temperature will lead to poor coloring, insufficient sugar accumulation and no decrease in acidity.

4. After Ganping is planted and put into production for three years, the plant yield can reach 3-5 kilograms, and it will enter the high-yield period year by year, with the highest yield of about 8,000 kilograms per mu. However, high yield has a great burden on trees, and the next year's flowering and fruiting will be poor.

5. Ganping's fruit is very easy to be too big, and it is easy to form floating fruit, and there is no data to show whether the fruit size is related to fruit cracking, so it is difficult to judge whether the fruit size is appropriate by artificial methods.
