Development of genetic markers for sexing Cannabis sativa seedlings
Cannabis sativa is a dioecious plant with a XY system. Only females produce cannabinoids in large amount. Efficient male removal is an important issue for the cannabis industry. We have recently identified the sex chromosomes of C. sativa, which opens opportunities for developing universal genetic markers for early sexing of C. sativa plants. Here we selected six Y-linked markers and designed PCR primers, which were tested on five hemp cultivars both dioecious and monoecious. We obtained promising results, which need to be extended using a larger number of individuals and a more diverse set of cultivars, including THC producing ones.
