Growing more resistant potato varieties is one of the most effective strategies to control late blight, to protect potato yield and to prevent harming the environment. The main aim of our study was to identify potato varieties with higher resistance to late blight and which were high yielding in Estonian conditions and suitable for organic farming. During the three-year trial, twelve potato varieties were tested at the Jõgeva Plant Breeding Institute (PBI) in 2010-2012. Foliage late blight (Phytophtora infestance (Mont) de Bary) and yield were estimated. First infection of late blight occurred in different times during the trial years. The three-year average infection level indicated that early varieties ‘Arielle’, ‘Impala’ and ‘Princess’ were more damaged than other varieties in the first estimation. Late varieties ‘Ando’, ‘Anti’, ‘Juku’ and ‘Sarme’ had higher late blight resistance. Their foliage damage remained less than 30% in the last estimation. The new medium variety ‘Teele’ had a lower infection rate than other medium varieties and did not significantly differ from late varieties. Based on these data, late varieties, early variety ‘Maret’ and medium variety ‘Teele’ can be considered suitable for organic farming. The new variety ‘Teele’ had the highest threeyear average tuber yield (52.8 t ha-1). Varieties ‘Impala’, ‘Princess’ and ‘Secura’ had significantly lower yield. Yield loss of these varieties might have been caused by higher late blight infection during trial years

The article presents the results of study of potato varieties and hybrids collection in the conditions of Kirov region, including varieties of modern Russian and foreign collections, interspecific hybrids of VIR, Falenskaya selection station and other scientific institutions for 300-350 samples annually. The study was conducted in contrasting weather conditions in 2017-2019. Sources of high productivity (705…887 g/bush): 129-10, Effekt (Russia), Lukawa (Czechoslovakia), Zorachka, Uladar (Belarus), Colomba (Netherlands) and others, and large potato tuber (100…140 g): Bellarosa (Germany), Lilea (Belarus), Irbitsky, Krepysh (Russia) were revealed. Due to big epiphytotic of late blight in 2017 varieties with high field resistance of foliage to late blight were revealed (7-9 points): Kufri Anara (India), Suzorye, Ragneda, Alpinist (Belarus), Gubernator, Skazka, Effekt, Vdohnovenie, Fritella, Legenda, 90-5-30, 55-03 (Russia); 387110.4, 678019 (Peru) and others. In 2019 samples with high late blight resistance of tubers were selected (9 points): Lilea (Belarus), Udacha, Ognivo, Lubava Legenda, 122-29, 90-6-2, 194-00, 591-97, 55-03, 56-09, 172-11, 6-1, 39-10, 132-07 (Russia), 389746.2, 678019 (BL-22), 678009 (BL-1.10) (Peru). Varieties of field resistance to viral diseases were selected: Lukawa (Czechoslovakia), Yanka, Ragneda, Zorachka, Charaunik (Belarus), Franzi, Albina, Kolomba, Sofia (Germany), Lazar, Skazka, Mayak, Udacha, Krasavchik, Charodey), Zolsky, Matushka, Nayada, Sudarynya, Kolobok, 42-7-40, 112-04, 184-05, 28-06, 48-224-10, 455-08, 431-08, 142-09, 5-7К, 1-13К, 218-12, 286-08, 40-14К, 16-25-1К, 16-29-33К, 56-09, 289-13. Assessment of starch content allowed to select varieties and hybrids with starch content above 20%: Bashkirsky, Zolsky, Lazar (Russia), Uladar, Vektar Belorussky, Manifest, Zhuravinka, Zdabytok (Belarus) and others. Hybrids 268-09 and 289-13 combined high starch content and high late blight resistance. The most valuable source material for potato breeding in the Kirov region are varieties and hybrids with a complex manifestation of warnings: Bellarosa, Albina, Sofia (Germany), 129-09, 40-14, 7-2В, 5-7 К, 268-08, 141-14, 289-13, 455-08, 56-09, 149-14, Kamensky, Irbitsky, Debryansk, Effekt (Russia), Kolamba (Netherlands), Zorachka, Сharaunik, Uladar, Altair, Lilea (Belarus), Lukawa (Czechoslovakia).

AbstractThe use of pathogen-resistant cultivars is expected to increase yield and decrease fungicide use in agriculture. However, in potato breeding, increased resistance obtained via resistance genes (R-genes) is hampered because R-gene(s) are often specific for a pathogen race and can be quickly overcome by the evolution of the pathogen. In parallel, susceptibility genes (S-genes) are important for pathogenesis, and loss of S-gene function confers increased resistance in several plants, such as rice, wheat, citrus and tomatoes. In this article, we present the mutation and screening of seven putative S-genes in potatoes, including two DMR6 potato homologues. Using a CRISPR/Cas9 system, which conferred co-expression of two guide RNAs, tetra-allelic deletion mutants were generated and resistance against late blight was assayed in the plants. Functional knockouts of StDND1, StCHL1, and DMG400000582 (StDMR6-1) generated potatoes with increased resistance against late blight. Plants mutated in StDND1 showed pleiotropic effects, whereas StDMR6-1 and StCHL1 mutated plants did not exhibit any growth phenotype, making them good candidates for further agricultural studies. Additionally, we showed that DMG401026923 (here denoted StDMR6-2) knockout mutants did not demonstrate any increased late blight resistance, but exhibited a growth phenotype, indicating that StDMR6-1 and StDMR6-2 have different functions. To the best of our knowledge, this is the first report on the mutation and screening of putative S-genes in potatoes, including two DMR6 potato homologues.
