Inbreeding as method for genotypic differentiation of initial material during development of 000-forms in spring rapeseed

The possibility of usage of inbreeding for development of promising stuff of 000-type in spring rapeseed was estimated. The number of light seeds and the variability degree of seed covering in connection with inbreeding generation were determined. It was shown, that use of inbreeding coupled with selection permit to obtain, starting with I6, practically stable forms of spring rapeseed with light seed covering.
