Characterization studies provide essential information for the conservation and use of germplasm in plant breeding programs. In this study, 103 Capsicum frutescens L. accessions from the Active Germplasm Bank of Embrapa Hortaliças, representative of all five Brazilian geographic regions, were characterized based on morphological characteristics and microsatel..

Morphological and genetic relationships between wild and domesticated forms of peppers (Capsicum frutescens L. and C. chinense Jacquin)

S.I.C. Carvalho, C.F. Ragassi, L.B. Bianchetti, F.J.B. Reifschneider, G.S.C. Buso and F.G. Faleiro

Capsicum chinense and C. frutescens peppers are part of the Brazilian biodiversity, and the Amazon basin is the area of greatest diversity for them, especially for that former species. Nevertheless, little is known about their evolutionary history. Aiming to identify genotypes with wild and domesticated characteristics, 30 accessions of the germpla.. Read More»

Genetic diversity studies of Brazilian garlic cultivars and quality control of garlic-clover production

G.S.C. Buso, M.R. Paiva, A.C. Torres, F.V. Resende, M.A. Ferreira, J.A. Buso and A.N. Dusi

The garlic cultivars grown in Brazil evolved from somatic mutations and clone selection by breeding programs and by the introduction of germplasm from other countries. Morphological characters have been used to differentiate these cultivars. Two hundred and six random amplified polymorphic DNA markers were utilized for a diversity analysis of the 17 most planted gar.. Read More»

Transferability of microsatellite markers of Capsicum annuum L. to C. frutescens L. and C. chinense Jacq.

S.I.C. Carvalho, C.F. Ragassi, I.B. Oliveira, Z.P.S. Amaral, F.J.B. Reifschneider, F.G. Faleiro and G.S.C. Buso

In order to support further genetic, diversity, and phylogeny studies of Capsicum species, the transferability of a Capsicum annuum L. simple sequence repeat (SSR) microsatellite set was analyzed for C. frutescens L. (“malagueta” and “tabasco” peppers) and C. chinense Jacq. (smell peppers, among other types). A total of 185 SSR primers were evaluated in 12 accessions fro.. Read More»

Genetic relationships among Heliconia (Heliconiaceae) species based on RAPD markers

L.P. Marouelli, P.W. Inglis, M.A. Ferreira and G.S.C. Buso

The family Heliconiaceae contains a single genus, Heliconia, with approximately 180 species of Neotropical origin. This genus was formerly allocated to the family Musaceae, but today forms its own family, in the order Zingiberales. The combination of inverted flowers, a single staminode and drupe fruits is an exclusive characteristic of Heliconia. Heliconias are cul.. Read More»

Novel and highly informative Capsicum SSR markers and their cross-species transferability

G.S.C. Buso, A.M.M. Reis, Z.P.S. Amaral and M.E. Ferreira

This study was undertaken primarily to develop new simple sequence repeat (SSR) markers for Capsicum. As part of this project aimed at broadening the use of molecular tools in Capsicum breeding, two genomic libraries enriched for AG/TC repeat sequences were constructed for Capsicum annuum. A total of 475 DNA clones were sequenced from both libraries and 144 SSR markers were tested on cultivated.. Read More»

Genetic divergence among accessions of melon from traditional agriculture of the Brazilian Northeast

The genetic divergence of 38 melon accessions from traditional agriculture of the Brazilian Northeast and three commercial hybrids were evaluated using fruit descriptors and microsatellite markers. The melon germplasm belongs to the botanic varieties cantalupensis (19), momordica (7), conomon (4), and inodorus (3), and to eight genotypes that were identified only at the species level. The fruit.. Read More»

Taking into account the scenario of melon production (Cucumis melo L.) in Brazil, it is notable the importance of the culture in the fruit market. The preference of the national market is concentrated in the fruits of the yellow type. Therefore, it is possible that the genetic base of the commercial cultivars is relatively narrow due to the loss of important genes i.. Read More»

Capsicum peppers are native to the Americas, with Brazil being a significant diversity center. Capsicum baccatum accessions at Instituto Federal (IF) Goiano represent a portion of the species genetic resources from central Brazil. We aimed to characterize a C. baccatum working collection comprising 27 accessions and 3 commercial cultivars using morphological traits .. Read More»
