Natural selection takes place while advancing generations of segregant populations of self pollinating species by the population (bulk) method. There is evidence that it maintains the individuals with greater grain yield. The question arises whether natural selection preserves the individuals which are more adapted only to the environment where the generation advance occurred, that is, if it contributes to increasing the genotype x environment interaction in the family assessment. This study was carried out to check this hypothesis in the common bean plant using families derived from a segregating population from a cross between the Carioca MG x ESAL 686 cultivars. The segregating populations increase in homozygosity was obtained by the population (bulk) method until the F14 generation, in three distinct locations in Minas Gerais state: Lavras, Lambari and Patos de Minas. Forty-seven F14:15 families were randomly taken from the population in each location and later multiplied to obtain F14:16 families. These families were jointly assessed with three controls using a triple 12 x 12 lattice design in the three locations of generation advance in the wet season of 1998/1999. All the estimated parameters showed that while advancing segregant populations by the population (bulk) method, natural selection acted to preserve the individuals which are more adapted to the environment in which they were advanced. |

Endophytic microorganisms live inside healthy plants and their isolation and identification may favor biotechnological applications. We isolated endophytic bacteria from Ilex paraguariensis callus cultivated in vitro for five months. Sequencing of 16S rRNA region to identify two isolates as Bacillus megaterium was used. The presence of bacterial cells in the intercellular spaces of callus cultures was detected by ultra structural analyses. The isolates were also evaluated for indole acetic acid (IAA) production and their potential in plant growth promotion of Phaseolus vulgaris L. The synthesis of IAA in the presence and absence of L-tryptophan was detected by colorimetric analyze for both isolates. In the presence of extracts from strains IPC06 and IPC07 the seedlings of P. vulgaris grew faster when compared to the control plants without the extract on in vitro tests. |
