Characterization of chromosome instability in interspecificity somatic hybrids obtained by X-ray fusion between potato (Solanum tuberosum L.) and Solanum brevidens Phil



Characterization of chromosome instability in interspecificity somatic hybrids obtained by X-ray fusion between potato (Solanum tuberosum L.) and Solanum brevidens Phil



Theoretical and Applied Genetics 84(7-8): 880-890



Asymmetric somatic hybrids between Solanum tuberosum L. and S. brevidens Phil. have been obtained via the fusion of protoplasts from potato leaves and from cell suspension culture of S. brevidens. The wild Solanum species served as donor after irradiation of its protoplasts with a lethal X-ray dose (200 Gy). Selection of the putative hybrids was based on the kanamycin-resistance marker gene previously introduced into the genome of Solanum brevidens by Agrobacterium-mediated gene transfer.
