INCREASING RAPE SEED YIELDS BY THE WAY OF HETEROSIS SELECTION

Usage of heterosis effect in rapeseed became possible after plenty experiments which proved existence of the significant heterosis. A level of heterosis in spring rapeseed hybrids varied from 20 to 50 %, in winter rapeseed hybrids – from 20 to 80 %. A meaning of heterosis in rapeseed depended on the estimation methods, environments, gene pool diversity. Scientists do their best to create alternative gene pools using in part method of rapeseed resynthesis.
