Characteristics of the Diploid, Triploid, and Tetraploid Versions of a Cannabigerol-Dominant F1 Hybrid Industrial Hemp Cultivar, Cannabis sativa ‘Stem Cell CBG’

Abstract: Hemp (Cannabis sativa L.) has recently become an important crop due to the growing market demands for products containing cannabinoids. Unintended cross-pollination of C. sativa crops is one of the most important threats to cannabinoid production and has been shown to reduce cannabinoid yield. Ploidy manipulation has been used in other crops to improve agronomic traits and reduce fertility; however, little is known about the performance of C. sativa polyploids. In this study, colchicine was applied to two prop… Show more

“…(lily) [ 43 ]. Since tetraploid H. syriacus has been reported to have a disomic segregating allotetraploid genome, the segregation of hexaploids would act as triploids, which might be linked with low fertility [ 13 , 44 ]. We report that the population developed from hybrid cultivars produce ploidy and chromosomal level diversity that might potentially provide novel phenotypes.…”

“…Network diffusion models can accommodate the aforementioned spatiotemporal complexities associated with SANEPs but require novel techniques of parameter estimation and model 1 Recent work, after the period of our study, developed pollen-immune or "triploid" cultivars of Cannabis sativa L. Crawford et al (2021) reviews the details of pollination on these new strains. This process requires monitoring to cull rogue male plants or removing plants that were feminized clones but hermaphrodized from environmental stress (Gerlach, 2019;Place, 2019aPlace, , 2019b.…”

“…Recently, triploid cannabis cultivars, that exhibit significant reduction in fertility, have been developed as a solution for crop loss from seed set during outdoor flower production in areas experiencing pollen drift (Crawford et al 2021). Triploid plants are frequently seedless, because unequal segregation of chromosome pairs during meiosis results in inviable gametes (Wang et al 2016).…”

“…Triploid plants are frequently seedless, because unequal segregation of chromosome pairs during meiosis results in inviable gametes (Wang et al 2016). The triploid cannabis cultivar Stem Cell CBG was found to produce 98% less seed than its diploid counterpart, following exposure to feminized pollen (Crawford et al 2021), which has lower viability than pollen from genetically male plants (DiMatteo et al 2020). If triploid cannabis continues to demonstrate significantly reduced seed set compared with diploids when exposed to pollen, then triploid cultivars will be sought for flower production.…”
