Embodiment 1

[0025] Embodiment 1: the seed potato breeding method of Zhongshu No. 3

[0026] (1) Firstly, the bred Zhongshu No. 3 potato was planted in the local field (Fangshan District, Beijing City) where commodity potato was produced. And selected in the field with typical varieties (: precocious, can be harvested 60 days after emergence, plant height about 60 cm, erect plant type, few branches, green stems, light green leaves, large compound leaves, wavy leaf margins, growth Strong potential. The flowers are white and luxuriant, easy to bear fruit naturally. The number of tubers per plant is 3-5, the tubers are concentrated, the tubers are medium in size and neat, and the rate of large and medium tubers can reach more than 90%. The tubers are oval and the top is round shape, light yellow flesh, few and shallow bud eyes, smooth skin), and normal growth plant tubers are used as the basic material for the detoxification of the stem tip. The climatic conditions in Fangshan District of Be...

Embodiment 2

[0038] Embodiment 2: the seed potato propagation method of No. 5 Zhengshu

[0039] (1) Firstly, the bred Zhengshu No. 5 potato was planted in the local field (Anren County, Hunan Province) that produces commodity potato. And selected in the field with typical varieties (early maturity and high yield, the number of days of growth is about 65 days, the plant type is erect and strong, the plant height is about 60 cm, the branch is 1 to 2, the growth potential is strong, the flower is white, and it can bear natural fruit. Single plant There are about 4 pieces of tubers, the tubers are oval, the navel is slightly smaller, the yellow skin is yellow, the bud eyes are shallow and thin, and the tubers are large and neat.) The tubers of plants with normal growth are used as the basic material for the detoxification of the shoot tip. The climate conditions in Anren County, Hunan Province are 280 days of frost-free period each year, the annual average temperature is 17℃~18℃, and the annua...

Abstract

The present invention relates to a reproduction method of potato seed. Said method includes the following steps : firstly, utilizing detoxified seedlings to reproduce raw seed potato seeds, then utilizing matrix cultivation to reproduce raw seed potato seeds, then using 85-90% of raw seed potato seeds to make native reproduction and can directly supply first-grade potato seeds for production, and utilizing residual 10%-15% of raw seed potato seeds to make cold allopathic reproduction of first-grade potato seeds, and then utilizing said first-grade potato seeds to make cold allopatric reproduction to directly supply and produce second-grade potato seeds.

Description

technical field [0001] The invention relates to a plant breeding method, in particular to a seed potato breeding method. Background technique [0002] Potato is an important grain and vegetable crop and industrial raw material crop. Potato is also the fourth major crop in the world after wheat, rice and corn. In the past two decades, the widespread use of virus-free seed potatoes has become the main trend of potato cultivation, and it has played a very important role in ensuring high and stable potato yields. [0003] However, at present, the method of breeding virus-free potato seeds is to firstly use potato tubers to carry out virus-free cultivation of shoot tips and section propagation of virus-free seedlings in triangular bottle stems, and then in high latitudes and high mountains where the climate is cold, the wind speed is high, and the isolation conditions are good. , plateau and other off-site breeding, and then transferred to the local production method. The cost ...
