Learn how to select tubers for seed. Seed potatoes should be examined especially carefully to select the healthiest and most productive tubers.
Clonal selection would be ideal from a seed point of view. That is, the selection of seeds from the most productive bushes when harvesting the autumn harvest. This is easy to do if you have summer potatoes planted. At this time, it is being cleaned up.
From the most productive bushes, small and medium tubers are selected for seeds. “Shrapnel” is quite capable of giving a full-fledged crop and does not take up much space during storage.
No matter how the tubers are selected for seeds, they must be clean, without traces of diseases, stains and wireworm damage. Cracks and wart growths should also not be, as these are symptoms of many diseases.
The size of the tubers for planting should be no more than a chicken egg. But there are varieties in which the tubers are very large and there are no little things. In this case, before sowing, the tubers are cut into several slices.
After digging, the seeds must be greened. Then they are better stored, and even mice bypass such seed material. In order for the tubers to get a green color, they are kept for two weeks on a sunny windowsill, stirring occasionally. Usually, during this time, the seeds acquire a good green color and become completely unsuitable for food – both for humans and rodents.
After that, the seeds are poured into bags and stored in the basement at a temperature of +4 ° C. Higher temperatures can lead to withering of the tubers, and their seed properties deteriorate.
The last seed check is carried out immediately before sowing. Then the tubers germinate in the light until sprouts 0.5-1 cm long are obtained. At this time, the degenerated tubers will be clearly visible with their filamentous sprouts. Such seeds must be selected and mercilessly thrown away.
The remaining seeds after checking it is quite possible to plant in the garden. Although sometimes all tubers give filamentous sprouts. This means that the seeds fell under the summer heat and degenerated. In this case, it is necessary to look for other seed material, there will be no sense from filamentous sprouts
