Abstract If there is a geographical area that will be particularly affected by the tragedy of September 11, that will be the international borders of the United States. It is understandable that a country that enters in a state of war after been attacked with enormous losses, reacts by closing its international borders. Such immediate reaction has now been substituted by a more strict control over everything that crosses the border but, a fact remains, the border life is not going to be what it used to before September 11. In the short run, everything that crosses the border has slowed down by new controls. In the long run many things will return to what it was before that Tuesday, but for a long while, life at the border will not be the same. An intense interaction of more than twelve million people from the two sides of the U.S.-Mexico border have made us live in many instances as if the border does not exist. This is the case among many of us in the way we practice our family life. For the planning of weddings, birthdays, reunions, ceremonies, the border is more virtual than real. This is reversed as we get more serious in what it means to the space where institutions, the laws and the governments reminds us that there is a line that marks the beginning and the end of two different nations.

Sweet sorghum figure as an alternative feedstock for ethanol production. The establishment of this culture in Brazilian production chain depends on the development of more productive and adapted cultivars. The aim of this study was to evaluate the general combining ability (GCA) of sweet sorghum lines and specific combining ability (SCA) of hybrid combinations as the agronomic and technological traits, and additionally to identify promising hybrid combinations for evaluation in advanced trials. Five restorer lines (R) and four male-sterile lines (A) were used in a partial cross diallel yielding 20 hybrids. The parental lines, hybrids and one check were evaluated in experiments carried out in a rectangular lattice design 5x6 with three replicates in two locations. The following traits were measured: flowering time, plant height, green mass yield, dry matter percentage, dry matter yield, juice extraction, total soluble solids content, sucrose content, purity, reducing sugars content, fiber content, sugars reducing total content, total recoverable sugars, hydrous ethanol, tons of per hectare, and ethanol production. There were differences between locations and genotypes for the traits. There was a significant effect of the genotype by environment interaction for most characters, except juice extraction, purity and reducing sugars content. There were a significant effect of GCA and SCA for most traits, indicating that additive and non-additive effects affect the phenotypic expression. Considering the effects of the GCA, the A line 201402B022-A, and R lines BRS 511, CMSXS643, and CMSXS646 were considered promising for exploration as parents in breeding programs of sweet sorghum in order to increase the ethanol production and the quality of the feedstock.The hybrids 201402B010-A x BRS 511, 201402B010-A x BRS 508, 201402B010-A x CMSXS646, 201402B022-A x BRS 511, 201402B022-A x CMSXS643, 201402B022-A x CMSXS646, 201402B022-A x CMSXS647 were the most promising for ethanol yield.
