Embodiment 1

[0042] Female parent: DMG231;

[0043] Sire: DMG240.

[0044] The cultivation method of industrial hemp in the present embodiment is as follows:

[0045] (1) In the field, sow and plant the female parent according to the conventional planting method of industrial hemp: sow the female parent on April 1, 2018.

[0046] (2) In the field, sow and plant the male parent according to the conventional planting method of industrial hemp; the male parent was sown on May 15, 2018.

[0047] (3) The parents are planted alternately at a ratio of 1:1. After the male parent enters the flowering period, the miscellaneous and weak plants should be pulled out. After the female parent enters the flowering period, all male plants should be pulled out.

[0048] (4) The hybrid industrial hemp seeds obtained by planting have a female plant ratio of 98%, planted in Changsha City, Hunan Province, with an average CBD content of 3.60%, an average THC content of 0.18%, and an average plant height of 1....

Abstract

The invention relates to the technical field of crossbreeding and in particular relates to a crossbreeding method of industrial hemp. The crossbreeding method comprises the following steps: seeding female parents DMG231, and seeding male parents DMG240; carrying out interlaced planting on the female parents DMG231 and the male parents DMG240; hybridizing the female parents DMG231 and the male parents DMG240 to obtain F1-generation seeds; and planting the F1-generation seeds to obtain F1-generation plants. Hologynic tall cannabidiol and industrial hemp crossbreeds cultivated by using the crossbreeding method are high in CBD content, are all female and are suitable for the characteristics of planting in southern areas in China.

Description

technical field [0001] The invention relates to the technical field of hybrid breeding, in particular to a method for hybrid breeding of industrial hemp. Background technique [0002] Cannabis is a 1-year herbaceous plant belonging to the genus Cannabis of the family Cannabinaceae. Industrial hemp refers to hemp with a tetrahydrocannabinol content of less than 0.3%, also known as hemp (hemp), which can be used for fiber, seed, and medicine. The hemp widely used at home and abroad is industrial hemp now. [0003] Industrial hemp research is a hot spot in recent years, especially the research on medicinal industrial hemp is in the ascendant. Among the more than 130 cannabinoids contained in the cannabis plant, cannabidiol (CBD) has always been an important drug-based raw material because of its non-addictiveness and great medical value. Clinical studies have shown that CBD has powerful anti-inflammatory, anti-convulsant, anti-tumor and anti-psychotic functions. CBD is main...
