“…pendulum, and C. pubescens are considered to be domesticated (Pozzobon et al, 2006;Moscone et al, 2007). It is, however, expected that new Capsicum species will be identified, especially in Atlantic Forest areas in Brazil (Bianchetti, 1996;Pozzobon et al, 2006). Moreover, in Brazil Capsicum plants are of economic, cultural and biological importance due to the use of the fruits in preparing dishes of typical culinary traditions, which is diverse among regions and sometimes unique in each region of the country.…”

Capsicum species are very important in Brazil because of economic, cultural and biological factors, and the country is considered to be a diversity center for this genus. Collection and maintenance of the genetic diversity in Capsicum are important to avoid genetic erosion. Besides the identification of species, the characterization and evaluation of accessions maintained in gene banks are of fundamental importance. For this purpose, multivariate methods have become an important tool in the classification of conserved genotypes. The objectives of this study were: i) to identify and characterize accessions of the Capsicum spp collection and draw conclusions about the potential use of certain accessions in different production sectors; ii) to estimate the genetic divergence among accessions using the Ward-MLM procedure, and iii) to evaluate the efficiency of the analysis of continuous and categorical data using the Ward-MLM procedure. Fifty-six Capsicum spp accessions were evaluated based on 25 descriptors, 14 of which were morphological and 11 agronomic. Based on the qualitative descriptors, it was possible to identify all species and, together with the agronomic descriptors, genotypes could be indicated with potential for use in various production sectors. Five was determined as the ideal number of groups by the criteria pseudo-F and pseudo-t 2 . The Ward-MLM procedure allowed the differentiation of the species C. annuum, C. frutescens, C. baccatum, and C. chinense in separate groups. The Ward-MLM procedure showed some level of efficiency in clustering Capsicum species analyzing morphological and agronomic data simultaneously.

“…The 13th chromosome pair shows distinctive characteristics among the subgroups. Previous morphological characterization and geographical distribution data of some wild Brazilian species (Barboza and Bianchetti, 2005;Bianchetti, 1996;Bianchetti et al, 1999) support this theory.…”

Pepper (Capsicum L.) is a major vegetable and spice crop worldwide. Global production of both fresh and dried fruit continues to increase steadily in terms of area harvested and yield. Various topics are addressed in this review, including recent additions to and clarification of Capsicum taxonomy, genetic resources of Capsicum, cytogenetic studies, the current status of our understanding of the mechanisms affecting the biosynthesis of capsaicinoids, the use of gene mutations to elucidate carotenoid biosynthetic pathways and their regulation, and recent advances in whole-genome sequencing and assembly.

“…Bianchetti (1996) estima que o gênero Capsicum abranja entre 20 a 25 espécies e que o maior número dessas espécies (13) é encontrado no Brasil. Trabalhos de coleta desse gênero identificam a Bacia Amazônica como o centro de diversidade genética para algumas espécies.…”

Obtenção e caracterização morfoagronômica de linhagens de pimenta do tipo Jalapeño Amarelo

RESUMO O gênero Capsicum, de grande importância mundial, ocorre tanto nos países tropicais como nos de clima temperado. De um total de 31 espécies, apenas cinco são consideradas domesticadas, as demais, semidomesticadas ou silvestres. Nos últimos anos, as pimentas passaram a ter maior demanda pelo mercado e, consequentemente, os trabalhos relacionados à caracterização, melhoramento e obtenção de novas cultivares receberam mais atenção dentro de instituições públicas de ensino e de pesquisa, assim como no setor privado. Este trabalho foi desenvolvido na Embrapa Hortaliças, com objetivo de caracterizar morfoagronomicamente linhagens de pimenta do tipo Jalapeño Amarelo, atividade essencial para o desenvolvimento de cultivares. Primeiramente foram identificadas três plantas segregantes da cultivar comercial do tipo Jalapeño Vermelho, que apresentaram frutos de coloração amarela. Com base nesse material, o trabalho foi desenvolvido em duas fases: na primeira, obtenção de linhagens homozigotas pelo método de Descendência de Uma Única Semente (do inglês Single Seed Descent); na segunda, caracterização das linhagens obtidas através de cinco descritores morfológicos de Capsicum propostos pelo IPGRI (1995) e posterior avaliação qualitativa das linhagens em campo, sendo usado o teste Scott-Knott para a análise estatística. Conclui-se que o método de melhoramento utilizado foi satisfatório, visto que, em 30 meses de trabalho, as linhagens avançaram cinco gerações (S5). A caracterização morfológica e a avaliação qualitativa permitiram identificar diferenças significativas entre as linhagens. As linhagens promissoras identificadas neste trabalho foram CNPH 25.368, CNPH 25.373, CNPH 25.374, CNPH 25.375 e CNPH 25.377.
