In Vitro Disease Resistance for Expression of Somaclonal Variation in Larix

Part of the NATO ASI Series book series (NSSA, volume 210)

Abstract

Somaclonal variation expressed by scleroderris canker resistance or susceptibility was examined using Larix decidua micropropagules generated from caulogenic calli. Callus had been initiated from adventitious shoots showing persistent resistance to the pathogen. Inoculation responses by these propagules were compared to those by adventitious propagules initiated from juvenile tissues, and presumed to be canker-susceptible. Inoculation of those hosts developed on callus from one ostensibly resistant plantlet showed no resistance. Colonization by the pathogen was complete on all shoots.
