Abstract The success of barley (Hordeum vulgare L.) cultivation and its adaptation to cropping systems relies on the knowledge and utilization of existing variability in germplasm banks. The objective of this work was to analyse diversity among pre-selected barley accessions to organize a working collection and to identify genotypes for a breeding program for irrigated barley in the Brazilian Savannah. The field experiment was conducted under irrigation in Planaltina, DF, Brazil. The plant population consisted of 433 accessions plus BRS 180 and BRS 195 as checks. The accessions were evaluated using fifteen morpho agronomic descriptors, in which 11 quantitative and four discrete. The interpolated control design was used for the statistical analysis. A genetic distance matrix was calculated using Gower?s coefficient. From the matrix, a grouping analysis was conducted, using the optimizing Tocher method and the graphic dispersion distance. The genetic distances varied between 0.025 and 0.572, with a mean of 0.256. The accessions were distributed in 18 groups by the Tocher method, which was directly related to the graphic dispersion. The existing genetic divergence in the collection under study helped the definition of accessions in crossing blocks from breeding programs directed to the savannah environment. |

The Brazilian Subtropical Highland Grasslands (Campos de Cima da Serra) is one of the main areas of endemism in southern Brazil. The complex biogeographic history that resulted in the floristic composition of the region is directly linked to the high degree of plant endemism found there. Here we present a current checklist for the endemic plants – the first taxonomically verified endemic species list for the region. The list comprises 273 endemic taxa (23.5% of its flora) representing 40 families and 117 genera, highlighting fifty-seven taxa reported as endemic from the region for the first time in recent years. Voucher specimens, original publication, locality information and distribution data are provided for each endemic taxon. Botanical collections in the Brazilian Subtropical Highland Grasslands have increased exponentially during the last four decades. However, 41 taxa are known only from the original collection record reported in their protologue. Our results emphasize the importance of the Brazilian Subtropical Highland Grasslands in terms of conservation of its flora and the importance of providing complete information on botanical collection labels as source for a robust knowledge of the flora. |
