Evaluation of quality indicators of potatoes of different ripeness groups in the forest-steppe of the Ob region

The results of the study of promising potato varieties in Novosibirsk region (2016-2018) are presented. The objects of the study were 14 samples of potatoes, 10 of them were modern domestic varieties not zoned in the West Siberian region. An assessment of the quality indicators of potato varieties was carried out in comparison with the following zoned varieties: Red Scarlett, Nevsky and Tuleevsky. To obtain an early harvest (75 days after planting), the varieties Lomonosovsky (36 t/ha) and Reggi (39 t/ha) were recommended for the early ripening group. In the group of mid-early varieties, the variety Samba (35 t/ha) was noted; in the mid-season group, the varieties Fritella and Vympel were distinguished (early yield 32 t/ha). High productivity during harvesting in the early ripening group was noted in the varieties Lomonosovsky (42 t/ha) and Reggi (44 t/ha). The Samba variety (44 t/ha) stood out in the mid-early ripeness group. In the mid-season ripening group, the recommended variety is Gusar (46 t/ha), which exceeded the Tuleevsky standard by 4 t/ ha. Among the varieties of the early group of ripeness, high starch content was noted in the varieties Lomonosovsky (16.3%) and Reggae (17.4%). In the mid-early and mid-season groups, one variety was distinguished in each, Samba (14.4%) and Fritella (17.0%). In the early ripening group, the dry matter content of all varieties was higher than that of the Red Scarlett standard, in the mid-early group the highest indicator was observed in the Samba variety (22.9%). In the group of mid-season varieties, the samples Vympel (25.4%) and Fritella (25.8%) exceeded the standard. High field resistance to late blight (9 points) in the epiphytotic year (2017) was revealed in the varieties Gala, Nevsky, Gusar and Fritella.
