The viability of hybrid potato seeds and material loss during first-year seedlings

As a result of the experiment, low germination energy and laboratory germination of seeds in single combinations of interspecific and intervarietal origin were revealed. At the same time, in most cases the manifestation of indicators was high – up to 100%. Significant differences were established between populations, their blocks in terms of plant losses at each of the stages of obtaining the first year seedlings: for growing plants in seed boxes, greenhouses and in field conditions. In general, about half of the plants of the combinations in the blocks with the mother forms of the varieties Verdi and Podoliya fell out during cultivation in seed boxes. Positive effect – the losses were twice less, obtained in combinations where the pollinator used the Podolia variety. The same was observed in the process of growing plants in a greenhouse, but was not confirmed during the growth and development of plants in the field. Key words: potatoes, hybrid seeds, interspecific, intervarietal crosses, germination energy, laboratory germination, plant losses in seed boxes, greenhouse and field.
