Plant Sex/Gender Identification – Cannabis and Hemp

Plant DNA Sex/Gender Identification, aka the plant gender test, is a new way to accurately identify male and female plants in a fraction of the time compared to visual sex detection. Our proprietary testing method identifies samples containing male-specific genetic markers without sequencing the underlying DNA.

Identifying sex at early stages reduces resources used on unwanted plants. To get started, simply place an order on this page. Then, obtain a DNA sample from a small piece of leaf material. Simply submit your samples to our lab and get your results in a matter of days! Plant DNA Sex/Gender Testing works with cannabis, hemp, and other species with genetically controlled sex determination (see below).

Sex/gender testing is an essential time saving tool during early stages of plant growth. It increases the cost-efficiency of growing from seed and helps you more effectively manage crop space. Determine the phenotype of your plants long before they are detectable by eye. ​Plant DNA Sex/Gender Testing works with the following types of plants:

1. ​Hemp and Cannabis (Cannabis sativa L.) (Mandolino et al., 1999 and van Bakel et al., 2011)
2. Papaya* (Carica papaya) (Deputy et al., 2002 and (Liu et al., 2004)
3. Asparagus* (Asparagus officinalis) (Harkess et al., 2017)
4. Nepenthes​* (carnivorous pitcher plants) (Scharman et al., 2017)

*When submitting samples for any species other than Cannabis you MUST include a piece of uncrushed whole-leaf tissue inside the collection kit.
