Molecular assisted selection was used to analyse linkage drag of different recurrent parents on two flanks of two populations and for restoring the ratio of two populations by SSR markers for ae.These are evenly distributed on chromosome 5.Linkage drags at the two flanks were controlled in 13.2 and 17.2 cM of CHBC1F2 populations by SSR markers and the linkage drag at one flank was controlled in 13.9 cM of DHBC1F2 populations.Genetic background resemblance of individuals of the CHBC1F2 population to the recu...
