Abstract
‘Heintooga’ is a new and distinct variety of blueberry plant that has the following unique combination of desirable features outstanding in a new variety. Heinetooga has slightly less than one fully developed seed per berry so that the fruit should be perceived as seedless by most consumers. Heinetooga has a medium to large fruit size with very good fruit color, picking scar and flavor. The fruit firmness of Heinetooga is moderately good to good and post harvest shelf-life is good so the fruit is suitable for shipping. Further, Heinetooga has broad soil adaptation.
