The assessment of hybrid combinations of potato according to significant traits such as resistance to basic diseases, high productivity and market condition of tubers was carried out in Kirov region in 2016-2018. As an object for the research the following new potato hybrids bred by Falenki breeding station, branch of FARC North-East, were taken: 27-07(165-00 ´ 282-97), 170-08 (Sierra ´ 93.14-99), 21-07 (165-00 ´ 282-97), 62-08 (9326-2 ´ Zhukovsky Early), 90-09 (194-00 ´ 45-7-17), 179-10 (Dina ´ 45-7-17), 455-08 (591m-62 ´ Dubrava). Early-ripe variety Udacha, middle-early Nevsky, mid-season Chaika recognized in Kirov region were used as standard. Phenological observations, assessment according to productivity (on the 65th day), total and commercial yield and disease resistance were carried out and chemical content of tubers was determined in the breeding nursery in accordance with the methodology instructions of potato breeding. As the result, according to economically valuable traits a promising selection number 170-08 has been chosen. In total yield its significant increase over the standard variety Udacha is 2.6 t/ha. The hybrid 170-08 tubers are round-oval shaped, the jacket is light-beige, the eyes are shallow, in number 5-6 on a tuber, the pulp is cream-colored. This variety combines high yield productivity (19.3 t/ha), and high top blight resistance (7-9 points). Also, 170-08 number is valuable when using for early yield (the productivity on the 65th day after planting is 14.6 t/ha). Conflict of interest: the authors stated that there was no conflict of interest.
