Abstract: | The colchicine-grafting method of doubling the chromosome number of potato cuttings was used successfully for producing hexaploids from the triploid species, Solanum x juzepczukii. All the plants with hexaploid flowers were triploid/hexaploid sectorial chimeras. Seeds were obtained from crosses of the hexaploid parts with both an andigena-tuberosum hybrid and a tuberosum variety. |
