Until the "new variety" of Shinshu apple is born
In Nagano Prefecture, which boasts the second largest apple production nationwide, eight types of original varieties are being developed. Before these were born, there were many developers' efforts and difficulties. Let's approach the depth of the birth of apple.
New variety of new varieties to look for rough stones
-A about 15 years at the shortest. Long years and strict selection
The season of the mandarin has finally arrived. In recent years, the popularity of Shinano Suite, Shinano Gold, etc., which are new varieties of Nagano Prefecture, are also growing.
"It looks like new varieties are being developed one after another, but there are many difficulties in the years before the birth. 7-8 years before sowing seeds and growing fruit. Select 100 and 10 good trees, even after planting.
It is even smaller gates whether new varieties will be born from these ten. Maejima must clear various conditions such as texture, shape, and preservation, as well as the taste. "
In addition, tests and surveys will be conducted on whether they can adapt to the actual cultivation environment.
It has been 15 years at the earliest until new varieties are crossed and enter the market. Long years and time and effort are spent, and delicious apples are born.

Imagine and make
There are so many types of apples grown at the test site. A crossing is performed in consideration of the characteristics of individual apples so that they can analyze and imagine the needs of 15 or 20 years ahead and respond to them.
"A few years later, small apples that can be eaten alone without peeling the skin may become popular," said Maejima. On the other hand, it is necessary to consider whether farmers are difficult to cultivate and difficult to transport. It is a condition of apples loved to be accepted by consumers, producers, and distributors.
