The granted patent US12002546B2 outlines a method for producing Cannabis plants with a day length neutral phenotype, which is significant for optimizing growth conditions and enhancing yield. The method involves a systematic breeding process that begins with crossing a parent plant exhibiting a day length neutral phenotype with a day length sensitive parent. This initial cross produces progeny plants, from which those exhibiting the desired phenotype or carrying the relevant trait are identified. Subsequent crosses between these selected progeny further propagate the day length neutral trait. A key aspect of the method includes testing the nucleic acid of the plants to detect specific alleles linked to the day length neutral phenotype, particularly focusing on variations in the endogenous UPF2 gene.
The patent details various techniques for nucleic acid testing, including nucleic acid amplification methods such as polymerase chain reaction (PCR) and allele-specific methods like probe hybridization and primer extension. The claims specify that the absence of a particular polynucleotide sequence (SEQ ID NO: 2) in the UPF2 gene indicates a day length neutral phenotype, while its presence suggests the plant is a carrier of this trait. The method also encompasses identifying variations in polymorphic sites, which may include point mutations, deletions, or insertions, that contribute to the day length neutral phenotype. This innovative approach not only enhances the breeding of Cannabis plants but also provides a genetic basis for understanding and manipulating phenotypic traits in this species.
