ANALYSIS OF DIHAPLOID INDUCTION AND PRODUCTION ABILITY AND SEED PARENT X POLLINATOR INTERACTION IN POTATO

The production of dihaploids is the first step in a potato breeding pr ogram at the diploid level. Dihaploid induction ability, dihaploid pro duction ability and seed parent x pollinator interaction were analyzed for 28 x 3, seed parent x pollinator combinations. This is the first report on significant interaction between seed parents and pollinators . Despite this interaction, IVP 101 had a significantly higher dihaplo id induction ability than the widely used pollinators IVP 35 and IVP 4 8. Previous findings on significant differences in dihaploid productio n ability between seed parents were clearly confirmed.
