Problems solved by technology

However, at present, there are still many technical bottlenecks in the hybrid breeding of Pinellia chinensis, such as uncertain hybridization conditions, low reproductive coefficient of mainly asexual reproduction, and inability to control F 1 Detection and screening of various characteristics on behalf of each other, affecting the selection of varieties and the transformation of results

Embodiment 1

[0009] Embodiment one, in figure 1 Among them, the present invention is a Pinellia hybrid and F 1 The multiplication method includes the following steps: Step 1, collection of pinellia varieties and establishment of germplasm resource nursery: first collect different types of pinellia seed stems, select healthy, uniform-sized stems, and colonize pinellia germplasm in sub-districts In the resource nursery, insert a card mark and carry out water and fertilizer management; Step 2, hybrid parent screening: From the different types of Pinellia germplasm resource nurseries, select a representative population with excellent traits as the hybrid parent; Step 3, Hybridization technique: the organ bracts of Pinellia flowers are slightly opened, the stigma is white with mucus, the surface of the stamens is smooth, and the pollination is not loose, and the pinellia flowers are artificially emasculated and pollinated. The best time for artificial emasculated pollination is 9:00- in the mor...

Abstract

The invention discloses a method for hybridizing pinellia tuber and propagating F1. The method comprises the following steps: 1, collecting pinellia tuber breeds and establishing an idioplasm resource garden; 2, screening a hybrid parent; 3, implementing hybridization technology; 4, implementing propagation technology: obtaining a seedling, propagating the seedling, proliferating a globoid, and regenerating an F1-generation plant; and 5. performing a pinellia tuber F1-generation product comparison test. The method can cultivate the pinellia tuber breed with good photosynthetic characteristic and excellent inner quality by adopting hybridization and propagation.

Description

technical field [0001] The present invention relates to a kind of pinellia hybrid and F 1 Multiplication method. Background technique [0002] Pinellia ternate (Thunb.) Breit. is a perennial herb belonging to the Araceae family Pinellia. It grows in mountains, farmland, streams or forests, and is distributed in most parts of my country. The tuber is used as medicine, which has the effects of drying dampness and reducing phlegm, reducing adverse reactions and relieving vomiting, eliminating mass and resolving mass. The commonly used traditional Chinese medicines recorded in the Chinese Pharmacopoeia rank 22nd among the 588 kinds of traditional Chinese medicine prescriptions. Modern studies have found that pinellia has functions such as anti-early pregnancy, anti-tumor, lowering blood fat, and protecting the liver, so it has attracted much attention at home and abroad. In recent years, due to the comprehensive rectification of pharmaceutical companies by the pharmaceutical ...
