Selective breeding method of Yunnan manyleaf paris rhizome high-altitude cultivated species

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...

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that the sources of the current varieties of Dionysus yunnanensis are chaotic, and the varieties and yields grown at high altitudes cannot be guaranteed. The genetic diversity of the altitude provenance, the selection of excellent germplasm with good indicators, and the cultivation of high-altitude cultivars with stable genes and performance, can promote the cultivation of Yunnan Zhonglou at high altitudes and Erban mountainous areas, increase yields, and promote Increase farmers' income
