Technology to obtain pre-base seed material of domestic breeding promising varieties potatoes

The purpose of research is to study the technology for obtaining prebasic seed material of promising varieties of domestic selection, providing the highest yield of tubers per unit area. The objects of study are promising domestic potato varieties Gulliver (St), Salsa, Reggie, Samba, Courtney, Meteor and Zumba. The results of studying four variants of plant placement - 1, 2, 3 and 4 plants in one pot are presented. The feeding area of potato microplants was 380 cm2; 190; 127 and 95 cm2, respectively. The largest number of tubers from a plant of varieties Gulliver, Courtney, Samba and Salsa can be obtained by providing a feeding area of each plant of 190 cm2. At the same time, 8.3 can be obtained from the plant; 6.9; 6.5 and 8.4 tubers, respectively. A decrease in the feeding area of microplants to 95 cm2 leads to an increase in the proportion of tubers of the fraction
