Breeding method for improved variety of Lonicera japonica Thunb No.1

Abstract

The invention relates to a breeding method for an improved variety of Lonicera japonica Thunb No.1, and is applicable to breeding of new variety of Lonicera japonica Thunb. Farmyard germplasm type Lonicera japonica Thunb branches from main producing area of pingyi county, ShanDong province, are collected; 15-25 Gy60Co-Gamma is taken for radiation induced mutation, and then cuttage and transplant are carried out; seed selection, cottage and transplant for variation individual plant are performed so as to form a strain; the Lonicera japonica Thunb No.1 obtained through variety comparison and production testing has thick and upright branches, oblong, linear oblong and oblong-ovate leaves, has dark green and thick leaves, and has more blossom buds; and flower buds are 4.5 cm in length, bracts are oval and oblong-ovate, the flower season comes earlier, saline-alkaline tolerance and barren resistance and strong adaptability are achieved, and plant diseases and insect pests are less. Compared with common Lonicera japonica Thunb, the Lonicera japonica Thunb No.1 has the advantages that the flower season starts two to three days earlier, the flower bud yield is improved by 16.20 percent, the content of galuteolin of flower bud is 0.106 percent, and the content of chlorogenic acid accounts for 1.75 percent, which is higher than the quality standard of Pharmacopoeia of the People's Republic of China (2010).

Description

Technical field [0001] The invention involves the selection method of fine varieties of honeysuckle, which is dedicated to the new varieties of honeysuckle "Renovong No. 1" that is suitable for breeding traits and suitable for production. Background technique [0002] The dry flower buds and the first blooming flowers are the dried flower buds of Lonicra japonica thunb.The effects of evacuation wind and heat are used to treat the symptoms of bloated scabies, throat parasites, van poison, heat poisoning blood, cold, cold, fever and fever.20 million kilograms.In addition to medicinal use, honeysuckle flowers are also widely used in the fields of soil and water conservation, greening, daily chemicals, food and beverages, livestock feed. [0003] In order to meet the market demand of gold and silver flowers in various applications, Leno Dong has large -scale planting in Shandong, Henan, Hebei, Shaanxi and other places. Traditional real estate areas are Pingyi and Mizhan, Henan.About ...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the chaotic cultivation of germplasm in the main production area of ​​honeysuckle, the lack of high-yield and high-quality cultivars, and the low and unstable situation of medicinal material yield and quality, the present invention determines the technical problem to be solved: take the type of Da Maohua farmhouse in the main production area as the basic material, provide The method of breeding fine varieties of honeysuckle "Liandong No. 1" is based on determining the cultivation type, cutting annual branches, and using 60 Co-γ radiation treatment enhances the variation, and through the observation of plant morphological characteristics and biological characteristics, selects the plants that produce more flowers and is easy to pick for directional cultivation, and improves the entanglement of branches, poor uprightness, small number of flower bud differentiation, and the yield of honeysuckle medicinal materials in Da Maohua farmhouse type plants Low adverse traits, the selected high-quality individual plants are used for cutting propagation, and the traits are basically stable, the quality of the medicinal materials is good, and the yield is high. It is suitable for large-scale promotion and standardized planting. The honeysuckle is excellent. Variety
