摘要

The invention relates to a biologically active substance from the class of steroid glycosides, which can be used in selection in crossing winter wheat with rye to produce new forms of triticale.A new steroid glycoside is proposed of the series of cholestane 3-O-{[α-L-rhamnopyranosyl(1→2)]-[α-L-rhamnopyranosyl(1→4)]-β-D-glucopyranoside}-(25R)-cholest-5-en-3β,19,22β,26-tetraol-[26-O-β-D-glucopyranoside], increasing the seed setting in distant hybridization.
