Abstract
In order to produce hemp with low cannabinoids and appropriate fiber yield, seeds of the IH3 (non drug type germplasm) and local variety (drug type cultivar) were mixed to 1:1, 2:1, 3:1 on base of seed weight ratio and cultivated for seed production. In the seed yield trial, the weight of 1000 grains were around 21 g, which was increased in proportion to the ratio of IH3 seeds but seed yield were 100 kg/10a, which were not significantly different by the seeds-mixing ratio. In fiber yield trials with seeds from seed yield trial, fiber yield ranged $193{\sim}198kg/10a$ which was not significantly different by the seeds mixing ratio but the content of THC(${\Delta}$-9-tetrahydrocannabinol) was lowered in proportion to the ratio of IH3 seeds. Variation of THC and CBD (Cannabidiol) level in the 150 plant cultivated with various seed mixing ratio reflected that the percentage of drug and intermediate type were decreased but non drug type were increased in proportion to the ratio of IH3 seeds.
