This morning I did a Facebook post about an asian pear that does well for
me in Seattle. This nashi is called Mishirasu.
You can see a photo of one of these hanging on the tree at that link about.
This pear has been used succesfully in breeding new varieties. I'm curious
to learn more about these. Is anyone growing the offspring of Mishirasu?
These are Kitahoshi, Hokuto, Hatsuhi, and Amatama?
For those of you who don't visit Facebook, here is the text of the post:
MISHIRASU NASHI- A HUGE ASIAN PEAR
In Seattle, these pears grow the size of grapefruit. Dripping with sweet
juice. Crunchy. A favorite with kids and squirrels! Looking somewhat like a
European pear on steriods with pure white flesh, and skin with a golden
background and a coarse russet. Recent genetic studies confirm that it is
probably an Asian x European hybrid.
Here are some facts about this pear, a.k.a. Mishirazu:
Origin: May trace back to seed from China. Found in Hokkaido about 1887
where it was originally called Iida Nashi. Tested in Aomori testing center
beginning in 1933. In 1956 this was the main cultivar grown in Hokkaido and
occupied 63% of production. Named 'Mishirazu' by Dr. Hoshino. Fruit ripens
in same period as Taihaku. Has been used in breeding and is a parent of
Kitahoshi (Misharazu x Nijisseiki), Hokuto (Mijisseiki x Mishirazu),
Hatsuhi (Chojuro x Mishirazu) and Amatama (Chojuro x Mishizaru). -- from
