Abstract: Provided are methods for determining if a cannabis sample comprises hemp or marijuana, or Cannabis sativa and/or Cannabis indica as well as primers and kits for use in the methods.

Abstract: An economical and accurate method for identifying sex of a Cannabis plant involves amplifying an amplicon of genomic nucleic acid molecules from a subject Cannabis plant using polymerase chain reaction (PCR), the amplicon being a genomic region containing the nucleotide sequence as set forth in SEQ ID NO: 1. The sex of the subject Cannabis plant is determined by determining whether SEQ ID NO: 1 is SEQ ID NO: 2 or SEQ ID NO: 3, where SEQ ID NO: 2 is in male plants and SEQ ID NO: 1 is in female plants. Preferably, high resolution melt (HRM) analysis is used to determine the sex of the subject Cannabis plant by comparing the HRM analysis to a control for male or female Cannabis plants. The amplicon can be amplified in both male and female plants with a common primer set.
