Embodiment

[0038] Beginning in 2015, using the industrial hemp variety Jinma No. 1 cultivated by the Economic Crops Research Institute of the Shanxi Academy of Agricultural Sciences and the late-maturing high-yielding hemp variety Lu'an Hanma introduced from Lu'an, Anhui Province as test materials, a high-yielding hemp variety provided according to the present invention The cultivation method of high-quality industrial hemp is tested as follows:

[0039] 1. Bud collection and screening

[0040] The male plants of Jinma No. 1 and Lu'an Hanma with excellent comprehensive characteristics were selected in the field as materials, and the flower buds on the male plants were collected during the budding and flowering period of the male plants at 7:00-9:00 in the morning on sunny days when the pollen vigor was high , use tweezers to pull out the pollen and place it on a glass slide, stain it with acetic acid magenta, observe the developmental stage of the microspores under a microscope, and scre...

Abstract

The invention provides a cultivation method for high yield and high quality industrial cannabis sativa. The method mainly includes the steps of: 1. flower bud collection and screening; 2. flower bud sterilization and inoculation; 3. anther induction culture; 4. callus redifferentiation; 5. adventitious bud proliferation and rooting; 6. pollen plant ploidy detection, and rejection of non-diploid plants; 7. transplantation of pollen plant seedlings; and 8. cross breeding, thus obtaining a holandric new line. The invention for the first time establishes a complete system for industrial cannabis sativa anther culture, also utilizes the method to produce super-male plants and female plants, and the plants are subjected to cross breeding to cultivate the holandric new line, thus significantly improving the yield and quality of cannabis sativa fiber, and providing a material basis for the development and utilization of cannabis sativa and cannabis sativa fiber.

Description

technical field [0001] The invention belongs to the technical field of economic crop cultivation, and in particular relates to a method for cultivating high-yield and high-quality industrial hemp.
