Abstract
The response to tissue culture of a series of related, agronomically useful, dihaploid (2n=2x=24) and tetraploid (2n=4x=48) S. tuberosum genotypes was assessed by regenerating shoots from leaf explants. Dihaploid genotypes that showed superior responses to their tetraploid parents were identified. Large differences in tissue culture response were also found between dihaploid genotypes derived from the same tetraploid parents. These results indicate that it should be possible to select agronomically useful dihaploid genotypes with good tissue culture responses for use in genetic manipulation experiments. Possible factors determining tissue culture response in S. tuberosum are discussed.
