ABSTRACT The aim of this study was to determine the mode of reproduction of a hybrid progeny derived from intraspecific crosses of Paspalum notatum through cytoembryological analysis and use of RAPD (random amplification of polymorphic DNA) molecular markers. Cytoembryological analysis allowed identification of the mode of reproduction of 28 plants that were selected after agronomic productivity evaluations. Of these, 19 had embryo sac morphology compatible with an apomictic mode of reproduction and nine had embryo sac morphology compatible with a […]

This study aimed to estimate the genetic diversity among Elephantgrass accessions using molecular markers. DNA samples of 30 accessions were obtained to perform PCR amplification using RAPD technique. Twenty random primers were used to obtain 88 high intensity and reproducible DNA bands (64 were polymorphic and 24 were monomorphic). Accessions were grouped by genetic distance estimates using UPGMA clustering. Genetic distances among Porto Rico, Santa Rita, IJ-7136 cv EMPASC 307; Mineiro and Mineiro Ipeaco accessions were null, suggesting that they […]

Bromus auleticus is a perennial, native species of the state of Rio Grande do Sul, which has demonstrated adaptability, potential yield of good quality forage as well as high morphological diversity. This work has analyzed band patterns from enzymatic systems and RAPD markers, with the objective to access the genetic variability in 16 accessions of Bromus auleticus from Rio Grande do Sul. The variability was evaluated using Jaccard similarity index. The method of grouping based on the average (UPGMA) was […]
