“…Previous research reported larger seed size (85 g) for LPM 17‐A, larger seed size (48 g) for LPM 21‐A and larger seed size (65 g) for Sun Oleic 97‐R and BRS 425 OL (76 g) (Gorbet & Knauft, 2000; Suassuna et al., 2015; Suassuna, Suassuna, Bogiani, et al., 2019). Because the genotypes related to A. ipaënsis and A. duranensis were selected for adaptation to tropical climate in Brazil, the reduction in seed size is more likely due to the environment when seeds were grown in the United States and therefore, cannot be directly associated with TSW epidemics in the experimental field.…”

Tomato spotted wilt disease (TSW) caused by tomato spotted wilt virus (TSWV) (genus Orthotospovirus) is a relevant disease in the peanut (Arachis hypogaea L.) crop. The effects of TSW in the plant are well documented. However, its effect on the seed physiology is unknown. The objective of this study was to evaluate the vigor and germination of peanut seeds from different genotypes with TSW symptoms. One cultivar and six germplasm lines related to A. ipaënsis Krapov. & W.C. Gregory and A. duranensis Krapov. & W.C. Gregory in addition to two U.S. cultivars (resistant and susceptible checks) were evaluated. Seeds were separated into symptomatic and asymptomatic classes. The mass of 100 seeds varied from 31 to 72 g among the genotypes. Germination and vigor were assessed by using a thermal gradient table (12-32 ˚C). Seeds that did not germinate during the test on the table were transferred to an incubator at 25 ˚C for three additional days to quantify total germination. Seed vigor was high across all genotypes and symptomology classes. Total germination was reduced for seeds kept at low temperature (12-16 ˚C) in the thermal table, regardless of genotype or symptomology. Overall, TSW symptoms did not affect germination, vigor, and seed size negatively.Abbreviations: b 0 , predicted maximum germination; b 1 , speed of germination; GDD, growing degree days; Germ 80 , growing degree days at 80% germination; M100S, mass of 100 seeds; TSW, tomato spotted wilt disease; TSWV, tomato spotted wilt virus; XP, growing degree days at maximum germination.

“…The trials in Herculândia and Tupã, western São Paulo State, were planted in the beginning of December, and severe spotted wilt epidemics were observed at both locations ( Table 3). The performance of 'BRS 421' and 'BRS 423' exceeded the overall means and checks, as observed for 'BRS 425' (Suassuna et al 2019).…”

“…Com demanda crescente nos últimos anos, a produção de amendoim tem sido atrativa para produtores de outras regiões do Brasil, em especial no bioma Cerrado. Desde 2010, a Embrapa expandiu o escopo do seu Programa de Melhoramento do Amendoim, incluindo o desenvolvimento de cultivares do tipo Runner alto oleico adaptadas para as principais regiões produtoras de grãos, incluindo o estado do Tocantins, resultando no registro das cultivares BRS 421 OL, BRS 423 OL e BRS 425 OL(SUASSUNA et al, 2019; SUASSUNA et al, 2020).

O estado do Tocantins é um importante produtor de grãos da região Norte do Brasil, que tem potencial para a produção de amendoim de elevada qualidade, visando atender à crescente demanda por este produto nos mercados interno e externo. Este trabalho teve o objetivo de avaliar seis linhagens de amendoim do tipo Runner alto oleico (1253 OL, 1952 OL, 2055 OL, 2101 OL, 2133 OL e 2136 OL) na área experimental da Embrapa, em Palmas-TO. As cultivares BRS 421 OL e BRS 423 OL foram utilizadas como testemunhas. Foi utilizado o delineamento em blocos casualizados com quatro repetições, sendo avaliadas seis linhagens na safra 2019/20 e quatro linhagens na safra 2020/21. O manejo das áreas seguiu as recomendações para produção comercial de amendoim, incluindo controle químico de plantas daninhas e doenças foliares. Os dados foram submetidos à análise estatística por meio de modelos mistos (REML/BLUP) utilizando o software Selegen. A significância dos efeitos de tratamentos foi testada por meio da análise de variância. Não houve diferença estatísticas entre os tratamentos (cultivares e linhagens), nos dois anos de avaliação. Porém, a média geral do experimento na safra 2019/20 (3.676,0 kg.ha-1) foi menor que a da safra 2020/21 (5.895,6 kg.ha-1). Em 2019/20, foi observado amarelecimento geral das plantas, embora não houvesse deficiência de nitrogênio ou outro fator associado ao manejo; amostras de sementes com deformações, manchas, rachaduras e avermelhamento da película também foram observados. Estes sintomas são muito semelhantes aos sintomas causados por mancha anelar, uma doença de etiologia virótica detectada em amendoim nos estados de São Paulo e Goiás. Com isso, é importante continuar a avaliação de novas linhagens, visando desenvolver cultivares mais produtivas e adaptadas ao cultivo em Tocantins, como também elucidar a etiologia dos sintomas observados na área experimental na safra 2019/20.
