Abstract

The article studied the passage of interstage periods and the yield formation of tubers of 93 potato varieties with different ripening periods. The selection of base clones was carried out in northern and southern conditions of Primorsky District in Arkhangelsk Oblast and the highlands of the North Caucasus at an altitude of 2 300–2 500 m above sea level. The growth, development and formation of tubers was significantly influenced by the length of day in the northern region and long sunshine hours in the highlands. The multiplication coefficient of plants in the highlands increased by 1.2–2.3 times compared to the northern region, while the highest increase was observed in late-ripening varieties. The weight of tubers of the early and mid-early ripening varieties was exceeded by 1.9–2.7 times compared with the northern region; the weight of the later period varieties was exceeded by 2.9–3.1 times.
