Use of the cytological method in selecting forms of potato producing unreduced gametes

Use of the cytological method in selecting forms of potato producing unreduced gametes

Sbornik Nauchnykh Trudov po Prikladnoi Botanike, Genetike i Selektsii 124: 86-90

In a study of 23 hybrids between dihaploids of Solanum tuberosum and various wild and cultivated diploid species, an association was found between disturbances at various stages of meiosis and the percentage of diploid pollen produced. The types of disturbances associated with formation of unreduced gametes are indicated; they involved especially disturbances at the tetrad stage. Forms able to induce gametes of this type are named and one is described, viz.
