Última Genetic divergence among elephantgrass cultivars assessed by RAPD markers in composit samples Scientia Agricola Daher,Rogério Figueiredo; Pereira,Messias Gonzaga; Pereira,Antônio Vander; Amaral Jr.,Antônio Teixeira do. Elephantgrass (Pennisetum purpureum Schum.) is native to regions of tropical Africa and was introduced in Brazil around 1920 through plantings imported from Cuba. It is currently one of the most widespread forage plants throughout the country. At first, there were two cultivars, Napier and Mercker, with well defined characteristics. New genotypes arose and it is believed that the large number of cultivars existing today in germplasm bank is due to duplicates. DNA markers for cultivar characterization are a very valuable tool, especially in situations where morphological and isoenzymatic markers have already been used as in the case of elephantgrass. Thus RAPD markers were used to estimate the genetic divergence among the Napier group elephantgrass...

Ano: 2002 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S0103-90162002000400001 Recurrent selection in inbred popcorn families Scientia Agricola Daros,Máskio; Amaral Jr.,Antônio Teixeira do; Pereira,Messias Gonzaga; Santos,Fabrício Santana; Gabriel,Ana Paula Cândido; Scapim,Carlos Alberto; Freitas Jr.,Silvério de Paiva; Silvério,Lucas. Although much appreciated in Brazil, commercial popcorn is currently cropped on a fairly small scale. A number of problems need to be solved to increase production, notably the obtaintion of seeds with good agronomic traits and good culinary characteristics. With the objective of developing superior genotypes in popcorn, a second cycle of intrapopulation recurrent selection based on inbred S1 families was carried out. From the first cycle of selection over the UNB-2U population, 222 S1 families were obtained, which were then divided into six sets and evaluated in a randomized complete block design with two replications within the sets. Experiments were carried out in two Brazilian localities. The analysis of variance revealed environmental effects for all...
