Abstract

<p>The large, triploid, yellow-skinned apple cultivar ‘Hirodaimisaki’ was bred at Fujisaki Farm, Hirosaki University. The parent cultivars were elucidated by genotype analysis using SSR markers. This analysis revealed that ‘Hirodaimisaki’ might be obtained from a combination of ‘Golden delicious’ × ‘Delicious’ strains. At our experimental site, the suitable harvest season for this cultivar is at the beginning of October, 150 days after full bloom. The skin color index at this time is around 2–3, remaining greenish in color. The fruit exhibits a flesh weight of over 450 g with a 12–14% soluble solid content and around 0.4% titratable acidity, which constitutes an appropriate balance between sweetness and acidity suitable for raw consumption. It is possible to alter the skin color to red using fruit bagging treatment. ‘Hirodaimisaki’ shows the potential to become a popular labor-saving, yellow-skinned cultivar suitable for gifting purposes.</p>
