“…Regarding the roots appearance, which is considered to be the most influential attribute taken into account (Melo et al, 2020b). Because chemical pesticides are not highly effective for controlling these pest species, since they develop in the soil and are protected in the roots, their management should be focused on the cultural control and plant resistance (Massaroto et al, 2014). 'Beauregard', 'BRS Amélia', and genotype MD1609026 were less resistant to insect damage in both experiments.…”

The average yield and quality of sweetpotato in Brazil are below the crop potential due to several traits that can be improved by plant breeding. This study aimed to evaluate the performance of sweet potato advanced clones with potential to be released as new cultivars, recommend cultivars with better attributes for grower's needs at the subtropical region of Brazil or to be used as parents in breeding programs. The genotypes MD1604002, MD1611010, MD1609023, MD1609024, MD1609026, and MD1610036 and cultivars Brazlândia Roxa, Beauregard, BRS Cuia, BRS Amélia, and BRS Rubissol, were evaluated during two seasons 2020/2021 and 2021/2022, in Canoinhas-SC. The experiments were conducted in complete randomized blocks design with four replications where plots were composed of three rows with 15 plants each, spaced 0.75 m apart with 0.35 m between plants. Storage roots were harvested 180 days after planting and evaluated for yield, appearance, insect damage, and shape characteristics. ‘BRS Rubissol’, the genotype MD1610036, with higher root yield, storage roots shape, appearance, and less susceptible to insect damage, and MD1609024, with a good root yield, similar or superior to cultivars Brazlândia Roxa, Beauregard, and BRS Amélia, stood out, and have potential to be cultivated in this region. ‘Brazlândia Roxa’ and genotype MD1611010 are potential sources of resistance genes to insect damage, which is one of the biggest challenges in sweetpotato production in Brazil.

“…Genotypes with high production and a commercially acceptable root format that favor harvesting and transport and resist the main pests and diseases are desirable (Massaroto et al, 2014). On the South American continent, pulp roots with white or cream color are the most demanded.…”

“…In addition, five roots (from the total production) per plot were evaluated for appearance (RA) using a scale of notes (Andrade Júnior et al, 2012): 1= nonstandard, with a very irregular shape, presence of large veins and deep cracks, 2= very uneven, with large veins and cracks, 3= non-uniform, with large veins and cracks, 4= slightly uneven with veins, and 5= regular fusiform shape, without veins or cracks. Resistance to damage caused by insect pests (RI) was determined using a rating scale: 5= roots free from damage, 4= roots with rare damage, 3= few commercial roots damaged, 2= majority of commercial roots damaged, and 1= commercial roots unacceptable for human and animal consumption (Massaroto et al, 2014).…”

Agronomic performance of experimental white-fleshed sweet potato genotypes in commercial fields

et al. 2022

Selecting new sweet potato genotypes that are adapted to the soil, climate, and cultivation conditions of the producing regions is necessary. Thus, the objective of this work was to evaluate the agronomic performance of experimental genotypes of white-fleshed sweet potato in commercial fields, seeking to evaluate their potential as commercial cultivars. The experiments were carried out in the municipalities of Presidente Prudente, Emilianópolis, Tarabai, and Álvares Machado in São Paulo state. The randomized complete block design with five repetitions was used in the experiments, where the genotypes UZBD-L1-04 and UZBD-L5-29 were evaluated along with the controls Ligeirinha Paulista, Canadense, and INIA Arapey. The assessed traits were tuberous root total yield, number of commercial tuberous roots, commercial tuberous root yield, average mass of commercial tuberous roots, percentage of commercial tuberous root dry mass, soluble solids, resistance to pest-caused damage, root length, diameter, and appearance. UZBD-L1-04 performed better than the other genotypes (the average of environments for tuberous root total yield was 31.76 t/ha), showing great potential as a commercial cultivar for the studied region.

“…Genótipos selecionados e adaptados a condições ambientais específicas são essenciais para melhorar a eficácia dos processos de produção (MELO et al, 2020b). Pois, um manejo correto do material para plantio, utilização de plantas saudáveis, adoção de genótipos que possuem alto rendimento, resistentes a insetos e com raízes saudáveis, podem contribuir positivamente para o aumento dos valores produtivos desta cultura (AMARO et al, 2019;MASSAROTO et al, 2014;SILVA et al, 2015).…”
