Recent research has documented the presence of AMF within <i>C. canadense</i> roots, however, this is the first study to successfully identify AMF species present in-situ using single spore rDNA barcoding. <i>C. canadense</i> successfully germinated in vitro with high germination rates (average 86.6%) for one population (SB000147) maintained at room temperature with a 16-hour photoperiod. Successful vigor continued to be monitored with regular multiplication and transfers. Eight AMF spores were identified, all members of the genus <i>Rhizophagus</i>. Seven spores identified as <i>Rhizophagus clarus</i> and one as <i>Rhizophagus irregularis</i>. <i>R. clarus</i> are commonly found in many semi-arid environments now including sand barrens.

They are promoted worldwide because of their health benefits. For optimal growth and productivity, blueberry crops need acidic soil pH, specific chilling hours, and an adequate atmospheric temperature. This delicate production equilibrium is under severe threat from climate change, potentially leading to reduced yields and increased cultivation costs unless new cultivars are developed for each edafoclimatic zone. Therefore, considering varietal replacements with more productive cultivars offering higher quality and better adaptability to local conditions is imperative. In this study, we employ polyploidization and in vitro tissue culture to promote variability and lay the foundation for new cultivar development. We report the successful induction of octoploids in three blueberry cultivars, namely ‘Biloxi’, ‘Legacy’, and ‘Duke’, through whole-genome duplication. Leaves and microstem explants were exposed to 0.1% colchicine for 24 and 48 hours in in vitro culture. After analyzing the polyploid level of 160 regenerated shoots using DNA flow cytometry, we obtained a total of 18 mutants, consisting of 8 mixoploids and 10 octoploids. The number of chloroplasts in the stomata was analyzed by fluorescence microscopy, revealing the duplication of these organelles in the induced octoploid plants. To our knowledge, this represents the first successful induction of octoploids in three blueberry cultivars -‘Biloxi,’ ‘Legacy,’ and ‘Duke’- achieved by exposing leaves and microstem explants to colchicine in in vitro culture.
