Abstract
A new sweet cherry cultivar, ‘Juno Heart’, was selected from the cross of ‘Benisyuhou’ × ‘Summit’ at Kennan Fruit Tree Section, Apple Research Institute, Aomori Prefectural Industrial Technology Research Center. The crossing was conducted in 1998, and it was selected from 35 seedlings in 2004. In Aomori, it matures in early July (about 57 days after full bloom), about 5 days after ‘Satonishiki’. The fruit size is large, being about 11 g. The shape is short cordate. The skin color is a yellow back ground color with dark red. The flesh is firm. The fruit is sweet (19°Brix) and shows low acidity (0.53% titrtable acidity). The stone size is large. However, because the stone is semifree, it is easy to remove. The S genotype is S1S6. It is pollinated by ‘Satonishiki’, ‘Benisyuhou’, ‘Nanyo’, and ‘Summit’, but it is incompatible with ‘Benisayaka’ and ‘Hokkoh’. It can be planted as a compatible pollinizer for ‘Satonishiki’. ‘Juno Heart’ is expected to provide gift or tourist farm attractions because of its attractive appearance and sweet taste.
