Vegetatif olarak üretilen bitkilerde mutasyon ıslahı

Islah programlarının genel amacı, lokal şartlara adapte olabilen, hastalık ve zararlılara dayanıklı, yüksek verimli ve tüketim gayesine uygun yeni çeşitler geliştirmektir. Eşeysel çoğalmadan dolayı meydana gelen karakterlerin açılımından başka, gerek doğal gerekse yapay olarak meydana getirilen mutasyonlar birçok bitki türünün önemli varyasyon kaynaklarıdır. Bu çalışmada, vegetatif olarak üretilen bitkilerde yapılan yapay mutasyon ıslahı çalışmaları ve genel prensiplerinin irdelenmesi amaçlanmıştır.

Mutation breeding of vegetatively propagated plants

The common objectives as usually breeding programs are to produce locally adapted, high yielding cultivars with quality that is desirable for the intended use. Besides the segregation of characteristics due to sexual reproduction, natural and induced mutations are important sources of variation in a lot of plants. In this study, by using many mutagenics, the evidence of the general principle of mutation breeding and variation in the veg'etatively propagated plants have been intended.
