O presente trabalho foi realizado objetivando avaliar dentre nove variedades de cana-de-açúcar (Saccharum officinarum L.), aquelas com maior potencial para uso como forragem para ruminantes durante o período de estiagem. O delineamento experimental foi em blocos ao acaso e as plantas foram cortadas duas vezes, sendo o primeiro corte com 17 meses de crescimento e o segundo 12 meses após. Foram estudadas as variedades CO 419; CR 45-3; SP 71-799;RB 73-9735; RB 73-9359; SP 71-6163; SP 70-1143; RB 72-454 e RB 78-5148. Houve diferenças significativas (P<0,05) entre as variedades para os parâmetros produção de matéria verde, produção de matéria seca, Brix e teor de proteína bruta. As variedades que se destacaram como promissoras foram RB 72-454, RB 78-5148 e RB 70-1143. |

There are two major centres of genetic diversification of common bean (Phaseolus vilgaris L.), the Mesoamerican and the Andean, and the legume is capable of establishing nitrogen-fixing symbioses with several rhizobia; Rhizobium etli seems to be the dominant species in both centres. Another genetic pool of common bean, in Peru and Ecuador, is receiving increasing attention, and studies of microsymbionts from the region can help to increase our knowledge about coevolution of this symbiosis. We have previously reported several putative new lineages from this region and here present data indicating that strains belonging to one of them, PEL4, represent a novel species. Based on 16S rRNA gene sequence phylogeny, PEL4 strains are positioned in the Rhizobium phaseoli/R. etli/Rhizobium leguminosarum clade, but show unique properties in several morphological, physiological and biochemical analyses, as well as in BOX-PCR profiles (,75 % similarity with related species). PEL4 strains also differed from related species based on multilocus sequence analysis of three housekeeping genes (glnII, gyrB and recA). Nucleotide identities of the three concatenated genes between PEL4 strains and related species ranged from 91.8 to 94.2 %, being highest with Rhizobium fabae. DNA?DNA hybridization (,47 % DNA relatedness) and average nucleotide identity values of the whole genomes (,90.2 %) also supported the novel species status. The PEL4 strains were effective in nodulating and fixing N2 with common beans. The data supported the view that PEL4 strains represent a novel species, Rhizobium ecuadorense sp. nov. The type strain is CNPSo 671T (5UMR 1450T 5PIMAMPIRS I 5T 5LMG 27578T ).
