Varietal identification of coffee seeds by RAPD technique
Crochemore,Maria Lúcia; Nunes,Liliane Moreira; Andrade,Giselly Aparecida; Molinari,Hugo Bruno Correa; Vasconcellos,Maria ElizabethThis study aimed the identification of cultivars and/or lines of Coffea arabica of commercial interest, using PCR-RAPD markers. The DNA of ground seeds lots of 12 cultivars and/or lines were evaluated with five primers (Operon OPA 01, OPA 04, OPG 11, OPY 16, and OPX 09) were obtained from a selection of 56 primers. The electrophoretic profiles allowed distinction among eight cultivars and/or lines as well as he...
Caracterização agromorfológica do maracujazeiro (Passiflora spp.)
Crochemore,Maria Lúcia; Molinari,Hugo Bruno; Stenzel,Neusa Maria ColautoEsse estudo descreve a variação genética de 55 acessos de Passiflora spp., constituídos de P. edulis, P. alata, P. coccinea, P. caerulea, P. foetida, P. giberti, P. macrocarpa, P. macrocarpa x alata, P. serrato digitata, P. suberosa e um acesso Passiflora sp. Vinte e dois descritores morfológicos foram avaliados sobre plantas isoladas em sistema de espaldeira e permitiram estruturar a diversidade encontrada. As...
Genetic diversity in passion fruit (Passiflora spp.) evaluated by RAPD markers
Crochemore,Maria Lúcia; Molinari,Hugo Bruno Correa; Vieira,Luiz Gonzaga EstevesThe objective of this study was to characterize the genetic diversity within a Passiflora collection by PCR-RAPD markers. Genetic analysis was performed in 70 accessions, representing 11 species of the genus Passiflora. The use of only five primers produced 136 reproducible polymorphic bands. The hierarchical classification showed high levels of dissimilarities between and within the species studied. A clear se...
