The objective of this work was to quantify the genetic diversity of elite genotypes of irrigated barley in the Brazilian savanna. Thirty elite barley genotypes from Embrapa Cerrados' collection were evaluated using 160 RAPD markers, 12 agronomic traits related to yield components, and 10 malting quality parameters. The genetic dissimilarity matrices based on molecular markers, quantitative traits, and malting quality characters were calculated and a cluster analysis was performed using the unweighted pair-group method with arithmetic mean (UPGMA) as grouping criterion. High genetic diversity among accessions were observed. The estimated genetic dissimilarities were weakly correlated, showing the complementarity of the different character groups. Selection indices and graphical dispersion analysis allowed the selection of promising genotypes and the indication of suitable crosses for maximizing the heterotic effects in breeding programs for irrigated barley in the Brazilian savanna. |

Rice blast (Pyricularia oryzae Cav.) is a limiting factor for upland rice production in Brazil. Efforts at the National Research Centre for Rice and Beans (CNPAF/EMBRAPA) have focused attention on developing integrated disease control for upland rice in the region that is dominated by savanavegetation known as cerrado, Sensu lato. Cerrado vegetation covers about 1.8 million ha, mainly in central Brazil. Annual rainfall varies from 1,000to 1,700 mm, more than 90%of it occurring during the wet season, fromOctober to April. |
