About features of initial stage of clonal microcultivation of remontant raspberry in vitro

The authors estimated the possibility for cultivation in vitro of remontant raspberry in autumn with use as explants of bud fragments isolated from substitution shoots and also determined the efficiency as cytokinin of thidiazuron with the purpose of acceleration of breeding for hard cultivated raspberry varieties. The regeneration ability in new hybrids on propagation stage was analyzed. The effective survival of bud explants from low part of fructiferous shoots picked in autumn during of cultivation on medium with thidiazuron was revealed. It was shown, that the farthest from shoot base buds have the greatest regeneration ability.
