A method for developing seeds for CBGa dominant Cannabis plants includes self-pollinating a female Cannabis plant having at least one defective THCa synthase allele to produce seeds, and collecting the seeds produced through self-pollinating. A method for developing seeds for CBGa dominant Cannabis plants includes crossbreeding a Cannabis plant having at least one defective CBDa synthase allele with a Cannabis plant having at least one of an active THCa or CBDa synthase allele to produce a CBGa dominant plant, and collecting the seeds produced through the crossbreeding. A Cannabis seed, developed from one of self-pollinating a Cannabis plant having a defective CBDa synthase allele or crossbreeding the Cannabis plant with another Cannabis plant that has one of either an active THCa or an active CBDa synthase allele resulting in a CBGa dominant seed.
