To start a hybridization program for a crop genetic drift is an issue? what is the effective number of parents to consider during the initial or first cycle crossing program to avoid genetic drift in a breeding population? Any explanation in this regard is highly appreciated.
effective number of parents for selective breeding of fish is minimum 50 pairs. More than this is also suggested. For plant I am not clear about. To avoid genetic drift More effective number of parents are preferable for all breeding program. Thanks.
Genetic drift will be theoretically minimum when purelines are being used as parents. However how we can calculate minimum number of parental lines to cross to eliminate drift I don't know. I think it will involve the genetic nature of the trait and also linkage.
