“…The possible reasons for these differences include the difference in genotypes evaluated as well as the environment of the trials. Interestingly, the average values obtained for yield component traits of fruit length (range, 2.1-5.8 cm), fruit width (range, 2.3-4.1), and fruit weight (range, 3.7-16 g) are similar to those reported in Brazil, Mexico, and Trinidad and Tobago (Martinez et al, 2021;Meraz et al, 2018;Ramjattan and Umaharan, 2021;Ribeiro et al, 2015;Santana-Buzzy et al, 2016), but higher than those reported by Camposeco-Montejo et al (2021) in Coahuila, Mexico.…”

“…The habanero breeding lines evaluated in our study had a maximum yield of nearly 20 tÁha À1 , and the hybrid check had a maximum yield of 30 tÁha À1 , which are lower than the yields of habanero in Taiwan (Zohoungbogbo et al, 2020) and in Brazil (Soares et al, 2020), but similar to the yield of habaneros evaluated in Trinidad and Tobago (Ramjattan and Umaharan, 2021). The possible reasons for these differences include the difference in genotypes evaluated as well as the environment of the trials.…”

Habanero (Capsicum chinense Jacq.) is widely grown and consumed in West and Central African countries, and viral diseases represent an important production challenge. Diagnosis of the viral species affecting habanero productivity in Benin is limited, and understanding this will enable more efficient host resistance breeding. During 2019 and 2020, we characterized the incidence and severity of the viral diseases infecting nine promising habanero breeding lines and one commercial hybrid check under open field conditions in Benin. The horticultural performance, including yield and yield component traits of the entries, was determined during the 2 years of the experiment. A randomized complete block design was used with three replications, each with 24 plants. Data were recorded on days to 50% flowering and 50% fruit maturity, yield and on the yield components of fruit weight (g), fruit length (cm), and fruit width (mm), as well as disease incidence and severity. In total, 35 leaf samples were collected for viral diagnosis among habanero breeding lines. We found that Pepper veinal mottle virus (PVMV; Potyvirus) was the overwhelmingly predominant virus in our trials, with an 80% incidence; however, we found frequent coinfection of PVMV with Cucumber mosaic virus (CMV, Cucumovirus), Polerovirus, and, to a lesser extent, Chili veinal mottle virus (ChiVMV; Potyvirus). The mean disease incidence across all entries was 60%. AVPP1932 and PBC 2010 had the lowest disease incidence (35% and 43%, respectively), whereas AVPP1929 had the highest (86%) disease incidence. The F1 hybrid check Afadja had the overall highest yield, with 30 t⋅ha−1, followed by AVPP1932, with 19 t⋅ha−1, both in 2019. There was a negative correlation between disease incidence and total yield (r = −0.44; P < 0.001), supporting previous studies indicating that viral diseases are major production constraints for habanero in West Africa. This study provides insight regarding the need to improve habanero for resistance to aphid-transmitted viruses and develop integrated pest management strategies to limit losses in Benin.

“…Das diversas espécies de pimentas do gênero Capsicum existentes conhecidas, cinco delas foram domesticadas pelo ser humano, sendo elas C. annuum, C. chinense, C. fructescens, C. baccatum e C. pubescens (Martinez et al, 2021). Evidências arqueológicas da América Central sugerem que Capsicum está entre os primeiros gêneros de plantas domesticadas, sendo produzidas há pelo menos 7.000 anos (Ramjattan & Umaharan, 2021).…”

Apesar de parecer pouco importante para a agricultura, o setor produtivo de pimentas (Capsicum) é muito extenso e promissor, fazendo parte fundamental do agronegócio brasileiro. O objetivo desse trabalho foi realizar uma revisão narrativa apontando os principais fatores referentes a utilização de diferentes métodos de secagem e temperaturas de armazenamento em sementes de pimenta, e como afetam a manutenção da qualidade fisiológica. Quanto à metodologia, utilizou-se o modelo de estudo baseado em pesquisa bibliográfica exploratória e abordagem qualitativa, trazendo informações a respeito da secagem e armazenamento adequados na manutenção da qualidade de sementes de pimenta, abordando os aspectos e fatores que interferem diretamente nesses processos. Observou-se através da literatura consultada que a secagem e armazenamento influem diretamente na qualidade das sementes, mas se faz importante destacar que processos no campo, como a época adequada de colheita, também impactam significativamente. Como o setor está em desenvolvimento, há uma necessidade significativa de pesquisa em tecnologia de produção de sementes com alta qualidade genética, física, fisiológica e de sanidade que resultem maior produtividade final, sendo a secagem e o armazenamento etapas cruciais desse processo. Através dos achados foi possível observar o quão importante é a realização da secagem e armazenamento adequados para manutenção do vigor, utilizando temperaturas e condições especificas conforme exigido para as sementes de pimenta. Embora seja elevado o número de publicações sobre o manejo e produção de pimentas, são necessários estudos mais específicos que identifiquem a otimização do processo produtivo de sementes, bem como as operações de secagem e armazenamento.
