I understood well about breed improvement! There was a very long history.

However, improving breeds takes time and effort, and the risk of failure can not be improved well, is not it high?

Is that so. For example, as I did with the page just before, if it is strong against pests but there are varieties that are bad and delicious but there are varieties that are weak against pests, we hope to have a breed that is strong and delicious for pests by combining them What?
However, it is not always possible to produce varieties with such properties. Then it costs money and it is not very good.So developed is " genetic modification technology.

Somehow difficult name ...

There is a sticker on the merchandise sold by supermarket etc, "Seal is a genetically modified crop".

Let's learn about "genetic recombination" next time.
