‘BRS F183’ (Potira): A dual purpose potato cultivar, with high yield potential and excellent French fry quality

Abstract

‘BRS F183’ (Potira) is a late-maturing and red skin potato cultivar, suitable for French fry processing, due to tuber high dry matter content of long oval shape, large size, light yellow flesh, and light fry color. It is also suitable for the fresh market due to its attractive tubers of intense red color, smooth skin and shallow eyes. In six trials, ‘BRS F183’ showed average tuber yields that did not differ from ‘Asterix’. The marketable yield was relatively high, reaching 98.5% in the tropical ecosystem. Larger tubers of ‘BRS F183’ than ‘Asterix’ were also observed in the autumn crop of the subtropical ecosystem. In most of the trials, the dry matter content was higher than that of ‘Asterix’, varying from 20.5 to 23.0%. A very low incidence of tuber disorders was observed in ‘BRS F183’, with the secondary growth lower than ‘Asterix’. ‘BRS F183’ presented medium tuber dormancy. Tuber glucose content suitable for French fry processing (≤1.2 mg g-1 of fresh mass) was shown by ‘BRS F183’ after harvest and storage at 7.5°C, 8.9°C and 20°C for up to 180 days, while ‘Asterix’ was suitable up to 120 days after storage at 8.9ºC. ‘BRS F183’ is moderately resistant to early blight and moderately susceptible to late blight. It is susceptible to PVY, PLRV, and root-knot nematode. Field observations indicate that resistance/susceptibility to soft rot, black scurf, and bacterial wilt of ‘BRS F183’ is not different from the main cultivars grown in the country. However, higher susceptibility to common scab was shown in some validation tests. ‘BRS F183’ was released in 2020 by Embrapa, as a product of the breeding program developed by Embrapa Temperate Agriculture and Embrapa Vegetables.

Resistance of potato genotypes to late blight

“…The late blight susceptibility of 'Agata' and 'Asterix' reported in this study has already been recorded in several studies conducted under different conditions and potato production systems (TÖFOLI; DOMINGUES; ZANOTTA, 2017;WOLTER, 2018;BUSNELLO et al, 2019). For the 'Potira' cultivar, similar results were described by Pereira et al (2022), who reported high susceptibility under field conditions. Although 'Agata' and 'Asterix' occupy a large space in the market due to their culinary qualities or ease of seed potato production (PEREIRA, 2011), both, as well as 'Camila', require a greater number of sprays with chemical fungicides (BRASIL, 2022) or efficient alternative products for P. infestans management due to their high values of severity and AUDPC under favorable conditions.…”

“…The genetic resistance of 'Cristal', 'Catucha', 'F50-08-01', and the resistant control CIP392.617-54 have been verified in other field experiment studies in southern Rio Grande do Sul (GOMES et al, 2009;CASA-COILA et al, 2019;PEREIRA et al, 2022). The stability of resistance to late blight is a highly desirable genetic trait in a potato breeding program, given the great variability of P. infestans isolates that normally occurs in the production environment in different regions of the planet (SAVILLE; MARTIN; RISTAINO, 2016) and our conditions (SANTANA et al, 2013;CASA-COILA et al, 2019).…”

Integrating Non-photochemical Quenching (NPQ) Measurements for Identifying Flood-Tolerant Soybean Genotypes in the Era of Climate Change

“…Globally flooding is one of the most damaging abiotic stresses, which affect approximately 17 million km 2 of land surface annually (Kaur et al, 2020). Climate change has been causing negative impacts on agriculture around the world, increasing impacts of biotic and abiotic stress on plant species (Brito et al, 2011(Brito et al, , 2014Diola, Brito, Caixeta, Pereira, & Loureiro, 2013;Pereira et al, 2022) and soybean production is no exception. Studies have demonstrated the negative impacts of climate change on soybean grain yield around world, including the waterlogging (Adegoye et al, 2023;Zhao et al, 2017).…”
