Embodiment Construction

[0024] The present invention will be further described below in combination with specific embodiments.

[0025] The breeding method of Yunnan Chonglou Honggan No. 1:

[0026] 1. Screening of high-quality provenance

[0027] Fifteen varieties of Dionysus yunnanensis of different geography and altitude were planted in a base at an altitude of 2,700 meters for domestication, and a provenance material with good growth and good yield was preliminarily selected from among them: the screening criteria mainly examined the adaptation to altitude, phenological period , rhizome growth and asexual reproductive capacity.

[0028] (1) Adapt to altitude: The altitude required to adapt to growth is 2700-3000 meters.

[0029] (2) Phenological period: the emergence period is late March, the seedling fall period is late October, the growth period is about 220 days, the flowering period is April-May, and the fruit period is May-September, 20 days earlier than other materials.

[0030] (3) The ...

Abstract

The invention discloses a selective breeding method of Yunnan manyleaf paris rhizome high-altitude cultivated species, which comprises the steps of: adopting different types of Yunnan manyleaf paris rhizome for domesticated planting, selecting germ plasm mateials which are good in adaptability to altitude and phenological period, relatively good in rootstock growth amount, relatively high in vegetative propagation capability and relatively good in plant characteristics as provenance for breeding, and further sieving and culturing cultivated species with relatively steady genes. The selective breeding method of Yunnan manyleaf paris rhizome high-altitude cultivated species not only improves purity and adaptability of high-altitude cultivated species, but also improves yield and adds economic income; compared with other provenances, the Yunnan manyleaf paris rhizome high-altitude cultivated species have relatively good generalization and planting foreground.

Description

technical field [0001] The invention relates to a method for breeding high-altitude cultivars of Dionysus yunnanensis. Background technique [0002] Paris polyphylla var.yunnansis (Fr.) Hand.—Muzz) is a perennial herb of Liliaceae, mainly distributed in Yunnan, Guizhou, Guangxi and Sichuan. There are 24 varieties of Paris polyphylla, most of which are All of them can be used medicinally, but only Yunnan Zhonglou and Huazhonglou are genuine medicinal varieties included in the National Pharmacopoeia. Since history, people have relied on natural wild resources to maintain the use of Yunnan chrysanthemum. Due to long-term excessive plundering and excavation, wild resources have declined sharply. Wild resources are far from meeting market demand. Artificial planting has become a solution The inevitable choice of scarcity. [0003] In recent years, some places such as Yunnan and Sichuan have begun to cultivate and introduce and domesticate. However, there are many varieties cult...
