...Breeding science is a field that studies the improvement of breeding techniques, but it is a type of applied science that is used in a wide range of academic fields, including general biology with a focus on genetics, biochemistry, and statistics. In actual breeding, various mutants with different genetic qualities are first artificially created, and then those that are useful to humans are selected and multiplied. Methods for creating mutants include crossbreeding by crossbreeding, nutritional hybrid breeding that creates mutations by grafting, artificial mutation breeding using radiation or chemicals, and cell engineering breeding that manipulates chromosomes and cytoplasm. ... *Some of the terminology explanations that mention "unusual things" are listed below.

…育種技術の改良を研究する分野を育種学というが,一種の応用科学であり,利用される学問分野は遺伝学を中心とした生物学全般,生化学,統計学など広い範囲に及ぶ。実際の育種では,最初に遺伝質の違ういろいろの変りものを人工的に作り出し,次に変りものの中から人間にとって有用なものを選抜・増殖する。変りものの作り方には,交配による交雑育種法,接木によって変異を作る栄養雑種育種法,放射線や薬品による人為突然変異育種法,染色体や細胞質などを操作する細胞工学育種法などがある。… ※「変りもの」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
