Industrialized hybrid seed production for bupleurum

Abstract

The invention discloses an industrialized hybrid seed production for bupleurum. The method comprises the steps that a bupleurum male parent resource is planted, female parent is seeded in front and back rows close to the rows of the male parent after the second week and the fourth week, when the male parent and the female parent enter the full blooming stage at the same time, the female parent terminal inflorescences obtained after pollen flying and all young and tender inflorescences except primary inflorescences are removed, the plants with the primary inflorescences flowering in advance orlag of flowering are pulled out, 2-7 days after pollen flying of female parent inflorescences is finished, male parent branches are slightly shaken to pollinate female parent pistils, after grains aremature, the grains become yellow from green and finally become dark brown, and after harvesting and drying, a lot of hybrid F1 seeds are obtained. By means of the method, a lot of castration work canbe prevented, and the F1 plants obtained by using the method have significant heterobeltiosis in the aspects of yield and effective constituent content.

Description

technical field [0001] The invention belongs to the technical field of Bupleurum seed production, and in particular relates to an industrialized Bupleurum hybrid seed production method. Background technique [0002] Radix Bupleuri is a common bulk medicinal material used in Asian countries such as my country, Japan and Korea. With the sharp decline in resource reserves of wild Bupleurum, artificial cultivation of Bupleurum appears to be particularly important. At present, 4 new varieties of Bupleurum chinense DC, Zhongchai 1-3 and Chuanbeichai 1, and 2 new varieties of Bupleurum chinense DC, Zhonghongchai 1 and Chuanhongchai 1, have been bred through selective breeding (B. scorzonerifolium Willd). Compared with local cultivated species and wild species, these varieties show higher variety consistency, yield and efficacy stability, and solve the problems of slow germination and irregular emergence of Bupleurum seeds. However, all new varieties of Bupleurum are systematical...

AI Technical Summary

Problems solved by technology

However, all new varieties of Bupleurum are systematically selected, and in production, Yaonong prefers to save their own seeds

However, Bupleurum is a cross-pollinated plant, and irregular breeding can easily lead to serious germplasm mixing and species degradation, which seriously hinders the industrialization of cultivated Bupleurum.

At the same time, due to the long-term systematic breeding, the breeding of Bupleurum bupleurum for high yield, high efficiency and high adaptability is also facing a bottleneck
