Cannabis sex analysis: Spotting the plant’s gender accurately

As a newbie or even professional cannabis grower, determining your plant’s gender is the beginning of a big adventure ahead! Especially in the context of growing marijuana for a medical purpose, it is important to identify the male and female plants so you can get the female flowers without any male flowers being around and turn your plants into seed bearers.

If the old-style growing keeps you waiting until week 6 just to make sure all plants reveal their gender to you, imagine how much you will lose and the risk of yielding plants below your expectation. Then, it’s time to identify your cannabis seedlings much sooner with our advanced DNA testing.

IS IT ENOUGH TO MAKE A PREDICTION?

Cannabis is a tall upright annual herb and generally dioecious (producing male and female plants separately). If you are a small-scale cannabis grower, it might seem easy to predict your plant’s gender based on your experience and prepare quick anticipation when you find undesired plants in your field. But, it is technically wrong and overwhelming if you own a big company with more than thousands of plants growing.

For growers who reared their plant through the propagation of stock mother, it will be easier to do because their plant will grow exactly the same. But, it will be difficult for seed growers since the seedlings don’t exhibit any distinction pattern.

Generally speaking, the cannabis industries are focusing their goal to produce female flowers with a high concentration of psychoactive component tetrahydrocannabinol (THC) in order to occupy the demand for marijuana. Since pollination lowers cannabinoid yields by ~50%, growers intentionally plant a female flower and discard any male. Meanwhile, based on studies, male flowers are expected to effectively produce a significant amount of flavor and scent-producing terpenes. Thus, their cultivation heading to the utilization in other compounds extraction, clothing materials and become a source for the future breeding program.

CAN WE DO A GENETIC MANIPULATION TO CREATE MONOECIOUS PLANTS?

There has been a big concern from growers who think the unexpected pollination caused by male flowers inflict economic loss. That is by manipulating the genes and plant’s hormones to create “feminized seeds”.

The idea behind feminized seeds is to use a chemical reversal process on the targeted female plants to produce viable pollen. Because the pollens are contributed by female sex chromosomes and it pollinating the female in other populations, all resulting progeny are female.

It sounds efficient in a certain way, but be careful since there is no guarantee that the plants will produce any seed. Any chemical input to alter the genetic structure can also increase the chance of inbreeding and impair the reproduction process that leads to some physiological disfunction. In addition, other significant impacts also may occur when the plants are exposed to other abiotic stress.

DNA TESTING TO GET THE ACCURATE RESULT FOR YOUR PLANT

According to that problem, and the need for genetic testing, MyFloraDNA has developed a cannabis sex ID service to optimize grower’s resources potential. Our genetic testing can give you a quick result within 3 days after germination and help you to decide whether you want to discard any undesired plant or record it for your germplasm collection.

Our top scientist expertise is the core of this service. We use Quantitative Polymerase Chain Reaction or qPCR as a precise method to detect a genetic marker of the male sex chromosome within the cannabis genome. Your sample will be processed during the PCR test into several cycles which allows a DNA polymerase to multiply the targeted short genetic sequence. This replication will be detected by our tool and ultimately detect the Y plant. The result will show which plant genetically contains Y chromosomes and which don’t.

This service has proven its efficiency to help growers reducing the inputs of water and lights in hydroponic systems as well as in the indoor cultivation systems using soil and controlled irrigation. We aimed to give a long sustainable benefit for our client by combining environmental handling and introducing modern genetics into the cannabis industry.
