New early-ripening potato variety Triumf

Abstract

The results of breeding work on the creation of an early-ripening potato variety Triumf for human consumption are presented. This variety is characterized by high stable early productivity, a complex of economically valuable traits and resistance to the most common diseases. Variety Triumf (hybrid number 91-08) was obtained on the basis of the targeted selection of genotypes using the intervarietal hybridization method as a result of crossing Nevskiy and Granat varieties in a breeding nursery in 2003 inthe conditions of the forest-steppe zone of Western Siberia. Its parentage includes species S. demissum and S. vallis-mexici. Variety testing (2004–2019) was carried out in various soil and climatic zones of Russia. In competitive variety testing in Omsk region in 2013–2016, productivity amounted to 32.6 t/ha on average, the maximum yield 35.8 t/ha was obtained in 2013 (4.0 t/ha higher than the standard variety Alyona). In the conditions of Moscow region in 2014-2016, the average yield amounted to 46.6 t/ha (4.9 t/ha higher than the standard variety Udacha), the maximum yield – 48 t/ha. In Tomsk region, the yield exceeded the standard variety Antonina by 3.0 t/ha in 2018. Variety Triumf is resistant to potato wart disease (Synchytrium endobioticum), its foliage and tubers are characterized by medium field resistance to late blight disease, increased resistance to common scab and black scab (Rhizoctonia solani), the main most common viral diseases in the forest-steppe and subtaiga zones of Western Siberia and chernozem zone of the European part of Russia. In 2019, the earlyripening variety Triumf for human consumption was included in the State Register of Breeding Achievements of theRussian Federation in the Central and Central-chernozem regions.
