First-class improved varieties of kernel apricot
1. At present, among the main varieties of kernel apricot produced in China, there is only one variety of Dragon King Hat, which is called "Dragon Emperor Big Almond" in the world. The fruit is flat and round, with an average weight of 18 grams and a maximum of 24 grams, with orange peel and thin pulp. The nucleation rate is 17.5%, and the dry nuclear weight is 2.3 grams. The kernel rate is 37.6%, the average weight of dried kernel is 0.8-0.84 grams, the kernel is flat and hypertrophic, the base is conical, the kernel skin is brown, the kernel meat is milky white, fragrant and crisp, and slightly bitter. The average yield of 5-6-year-old almonds is 3.2 kg. Self-spending is not fruitful.
2. Chaoren Chaoren was selected by Liaoning Fruit Tree Science Research Institute in 1998. The fruit is flat and oval, with an average single fruit weight of 16.7 grams. The peel and pulp are orange and free from the kernel. The core-shell is the thinnest, with an average nuclear weight of 2.16 grams and a nucleation rate of 18.5%. The rate of producing kernel is 41.1%, and the average weight of dry kernel is 0.96 grams, which is 14% higher than that of Dragon King Hat. The kernel meat is milky white and tastes sweet. The average almond yield of 5-10 years old is 4.3 kg, which is 37.5% higher than that of Longwang cap. The seed setting rate of self-flowering is 4.2%.
3. Youren was selected by Liaoning Fruit Tree Science Research Institute in 1998. The fruit is flat and ovoid, with an average weight of 15.7 grams per fruit. The average dry nuclear weight is 2.13g and the nucleation rate is 16.3g. The average weight of dried kernels is 0.90 grams, and the kernel yield is 38.7%. The kernel is large and thick, full and sweet. The fat content in kernel meat is as high as 61.5%, which is 37% higher than that of Dragon King Hat. It is the variety with the highest fat content in almonds. The average yield of 5-10-year-old almonds is 3.3 kg, which is 4% higher than that of Longwang cap. Self-spending is not fruitful.
4. Fengren Fengren was selected by Liaoning Fruit Tree Science Research Institute in 1998. The fruit is flat and oval, with an average weight of 13.2 grams. The dry nucleus weighs 2.17 grams, the nucleation rate is 16.4%, and the nuclear surface is protruding. The average dry kernel weight is 0.89 grams, and the kernel rate is 39.1%. It is kind, full and sweet. The average almond yield of 5-10 years old is 4.4 kg, which is 38.5% higher than that of Longwang cap. The self-flowering seed setting rate is 2.4%, which is extremely productive. It is a pollinated variety of super benevolence.
5. Guoren Guoren was selected by Liaoning Fruit Tree Science Research Institute in 1998. The fruit is flat and oval, with an average weight of 14.1 grams. The dry nuclear weight is 2.37 grams, and the nucleation rate is 21.3%, which is the variety with the highest nucleation rate. The average dry kernel weight is 0.88 grams. The kernel rate is 37.2%, and the almonds are full and sweet. The average yield of 5-10-year-old almonds is 4.1 kg, which is 27.1% higher than that of Longwang cap. Self-spending is not fruitful. The above four new varieties had strong disease resistance, and no diseases such as gummy disease, bacterial perforation and fruit scab were found after years of observation. It has strong cold resistance and can be cultivated in the south of Gongzhuling, Jilin Province. Also belonging to this class are new strains such as 80D05, 80A03 and 79C13.

Brief introduction of new pear strain 4MULY20
The new pear strain 4Mel 20 is a new early maturing pear line bred by using Xizilu as female parent and Cuiguan as male parent. After three years of fruit and character observation of female parent tree and high grafted tree, the agronomic character of this strain is stable. The main variety characteristics are as follows: this strain has strong growth potential, erect tree posture, large and thick leaves, easy flower bud formation, complete flower bud and large amount of pollen. The fruit matured early and matured around July 20 in Hangzhou. The average fruit weight is about 250 grams, the fruit is more uniform, the fruit is round or tall, and the fruit is round.

Late ripening peach treasure red leaf winter peach
The red leaf winter peach blossoms in the north of Henan Province on March 25, and begins to bloom on April 1, with pink flowers, 5 petals, 3.5-4 cm in diameter, 7-10 days of flowering, pink peach blossoms and purple peach leaves. It has become the only red landscape worth watching in spring. With the change of season and temperature, the purplish red peach leaves slowly changed into copper green from the base up, but the top shoots and new leaves were still purplish red, forming on the same branch, and the lower leaves were copper green.
