specific Embodiment

[0011] Selected from the wild Mongolian subspecies population, excellent individual plants with large fruit and few thorns were allocated according to the ratio of male and female to 10:1 for free pollination hybridization. The obtained hybrid progeny seeds were sown and cultivated in Dengkou, Inner Mongolia for adaptive domestication selection.

[0012] Breeding criteria: First, the fruit is large (the fruit weight is more than 30 grams) and has no spines or less spines (the number of spines on a 2-year-old branch is less than 3); the second is the short plant, which is more than 20% shorter than the Russian variety Chuysk. , the average yield per plant is more than 1kg; the third is strong drought resistance, and the damage rate of fruit fly to fruit is less than 10%. The bred new variety was named "Shalin No. 1".

[0013] Sarin 1 is characterized by 3 aspects:

[0014] First, as shown in Table 1, the fruit is relatively large, yellow, and cylindrical. The mince weighs 33 ...

Abstract

The invention discloses a method for cultivating sea buckthorn with large fruit and high resistance, which is characterized in that a plurality of superior individual plants with large fruit and less thorn are selected from the wild Mongolian subspecies of sea buckthorn, and are configured with the female-male proportion of 10 : 1 for open pollination and hybridization; the generated progeny seedlings are cultivated; and a hybrid clone with small plants, large fruits without thorns and strong fruit fly resistance is selected and named as Sarin No.1. The sea buckthorn cultivated through the method has the advantages of fine variety and strong adaptability.

Description

technical field [0001] The invention relates to a method for cultivating new plant varieties, in particular to a method for cultivating large fruits and high sea buckthorn resistance. Background technique [0002] Among the existing sea buckthorn, Chinese sea buckthorn is resistant to drought, high temperature, barrenness, and is very resistant to stress; the excellent sea buckthorn varieties bred in Russia and Mongolia have large fruit, no thorns, and relatively high economic benefits. [0003] The above-mentioned existing sea buckthorn has at least the following shortcomings: the Chinese sea buckthorn has many small thorns, the economic benefit is relatively low, and the enthusiasm for mass cultivation is not high; the sea buckthorn in Russia and Mongolia is relatively weak in drought resistance, high temperature resistance, and barren resistance, and the adaptability is relatively poor. . SUMMARY OF THE INVENTION [0004] The purpose of the present invention is to prov...
