Papaya is a genetically narrow-based crop, with few genetically distinct cultivars available for planting. This study aimed at the sex conversion of genotype 'Cariflora', from the dioecious to the gynoecious - andromonoecious stage, by means of RAPD marker-assisted introgression of the M2 allele. Hierarchic clustering in the BC 2 generation showed three plants close to the recurrent parent (15, 18 and 89) with desirable phenotypic traits; the genetic divergence matrix indicated that this similarity was 84, 81 and 76 %, respectively. The genetic dissimilarity matrix presented a mean genetic distance between the recurrent parent and the BC2 plants of 75.7 %, which was less than the expected 87.5 %. The phenotypic selection, applied in the BC 1 and BC2 populations, partly explains this deviation in favor of the donor parent. |

Conteúdo: |
The formation of water film on surface of materials, mainly in the soil minerals, is a important feature because it is related with many physical, chemical and biological processes occurrin in soils. One of the main properties involved is the capillary phenomenon, which is related to the interaction of the van der Waals force. The investigation of this property, in the nanoscale, introduces a new concept to characterize the dynamic of the aggregate, whic is normally observed in the micrometer and macro scale. |
