Publication number: 20210029956Abstract: The present invention relates to a diploid, fertile, self-compatible and highly homozygous tuber-bearing Solanum species potato line designated Solyntus. The potato line Solyntus produces 15 to 20 tubers per plant. The tubers have a yellow flesh. The phenotype of the plant and tuber is stable through both sexual and asexual reproduction. The potato line Solyntus is produced from seeds or by asexual reproduction of tubers or other plant parts.Type: ApplicationFiled: July 29, 2020Publication date: February 4, 2021Inventors: Willem Hendrik Lindhout, Adriaan Willem van Heusden, Ate van der Burgt, Michiel Erik de Vries, Su Ying, Menno ter Maat
