Blueberry x DC GammaBloom f1

EVD420 Yo, what’s up growmies 🤝 This is Blueberry × DC Gamma Bloom — F1. Not expecting much visible diversity at this stage, but F2 should bring something really interesting. For now, it’s all about observation and laying the groundwork for the next generation.

EVD420 Yo, what’s up growmies 🤝 Update on Blueberry × DC Gamma Bloom. Upon returning, I noticed that the plants had stretched into the light. Some minor light burn occurred, but nothing critical. All plants were defoliated and switched to flower, and the burned sections were carefully removed.

EVD420 During this reporting period, the line underwent standard structural control. All plants were defoliated and topped to regulate height and maintain canopy control. Selected males were separated for pollen collection. Phenotype observations: • Plant #1 was identified as male and moved to a separate box for pollen collection. Notably, the male expresses 7-finger leaves, which may indicate a stronger Blueberry influence. • Plant #2 shows a stronger DC Gamma Bloom dominance. It expresses 7 to 9-finger leaves, suggesting a more pronounced DC structural trait. • Plant #3 appears to lean more toward the Blueberry side, consistently showing 7-finger leaves and a morphology closer to that parent line. The population currently displays a visible split between Blueberry-leaning and DC-dominant expressions. Flowering observation phase continues.

EVD420 During this reporting period, sex identification was finalized and structural correction completed. The remaining plants expressed female characteristics and were confirmed as females. Both plants were topped (apical control finalized) to regulate vertical growth and improve canopy structure. They have now been fully transitioned into flowering. The selected male plant remains isolated and is currently being maintained for pollen collection. At this stage, the population has been reduced to two flowering females, with controlled pollen available for targeted crosses. Flowering observation phase begins.

EVD420 lowering initiated on February 20. Pollination Phase • Plant #2 and Plant #3 were moved for controlled pollination. • They remained in isolation for several days during the pollination window. • After completion, both plants were returned to the main flowering box. Current Status The line is now in early flowering stage, with selected branches undergoing seed development. Canopy remains stable following the transition and temporary relocation.
