The rooting and growth of “Ryofu” are good and seedlings are easy to raise. Rooting and growing after planting are good, and tree height and vertical spread are both excellent. The “Ryofu” tree is slightly upright, easy to tailor, and suitable for mechanized cultivation. Resistance to the cold is strong, but resistance to laceration-type frost damage is slightly inferior to that of “Kanayamidori”. Resistance to disease is slightly stronger for anthracnose, stronger for ring spot, making this cultivar stronger than “Yabukita”.

The quality of the first flush tea is bright green in color and luster, infusion is transparent, astringency is strong and umami can be tasted, and it is clean and excellent. There is moderate astringency, but the balance with umami is good. Both the second and third flush teas have higher yields than “Yabukita” and is of excellent quality.
