Line selection - Keito Senbatsu (English spelling) Line selection
It is one of the basic operations in plant and animal breeding. In crops, many seeds can often be produced from one individual. Therefore, one individual can produce many offspring in the next generation. Raising the offspring of one individual as a group in this way is called lineage breeding. Several individuals are selected from one lineage, and lineage breeding is done individually for the next generation, with these sibling lineages treated as a lineage group. Selection between lineage groups and between lineages is called lineage selection in a broad sense. It corresponds to individual selection and mass selection.

動植物の品種改良(育種)の基本的な操作の一つ。作物では1個体からたくさんの種子が採種できることが多い。そのため,1個体の子を次の世代にたくさん作ることができる。このように1個体の子を群としてまとめて育成することを系統育成という。1系統から数個体を選び,個体ごとに次の世代に系統育成をするが,この兄弟系統を一つの系統群として扱う。系統群間および系統間の選抜を広い意味で系統選抜といっている。個体選抜や集団選抜と対応するものである。
