While other agricultural crops have benefited from decades of breeding efforts that allowed development of stable parental lines that when crossed produce 100% uniform progeny via seeds, Cannabis breeding and cultivation are lagging behind.
Medical and Recreational instability – Mother plants age with time, and are susceptible to both mutative changes and differentiating expression levels of genes. Relying on Mother Plants is the biggest hurdle in both Cannabis and Hemp production since just like in humans, whereby an adult has the same DNA from infancy but over time mutations and genetic expression levels change thus leading to different phenotypic profiles, so do Cannabis mother plant change over time. These differences are pronounced in:
Hemp- The same problems indicated above for Medical and recreational cannabis apply in Hemp in addition to regulatory requirements of testing THC concentrations that cannot surpass a certain limit. The genetic instability of Hemp is creating a very big strain on grower’s capability to meet with these legal requirements as plants outdoor are also susceptible to external abiotic pressures such as temperature and light that influence and differentiate, unpredictably, the chemical concentrations of THC.
