Ethanol production from sweet sorghum depends on the quality of the biomass and sugars in the juice extracted from the plant. However, quality may be compromised by Diatraea saccharalis (Fabricius) (Lepidoptera: Crambidae) or sugarcane borer infestation. This study evaluated the effects of infestation by the pest on sweet sorghum juice productivity and quality. Sorghum variety BRS506 was planted in an experimental area with 4,800 m2. Samples were harvested at 115 days after planting and the following variables were evaluated: physical injury caused by the pest in the stalk, juice yield, total soluble solids in the juice and chemical composition. Additionally, the presence of Fusarium sp. in the stalks was checked. A significant difference was detected for juice yield, with lower values found in bored stalks resulting in a 2.62% decrease in juice yield at an infestation intensity of 4.16%. Infestation of D. saccharalis also caused a reduction of 34% in the plant sucrose content and significantly decreased fiber, lignin and ash rates. Infestation by D. saccharalis in sweet sorghum caused a significant reduction of plant height, juice productivity, and was associated with the presence of Fusarium sp., and sugar and fiber reduction. |

Analysis of DNA polymorphisms allows for the genetic identification and precise discrimination of species with a narrow genetic base such as common bean. The primary objectives of the present study were to molecularly characterize commercial common bean varieties developed at various research institutions using microsatellite markers and to determine the degree of genetic diversity among the bean varieties analyzed. Fifty cultivars representing 12 grain classes and 64 genitors, i.e., accessions used to develop these cultivars, were characterized. Based on an analysis of 24 simple sequence repeats, the estimates for the average number of alleles and genetic diversity were 8.29 and 0.646, respectively. The combined probability of identity was estimated at 7.05 x 10(-17), indicating a high individual discriminatory power. Thirty-two percent of the cultivars exhibited heterogeneity for multiple loci that reflected either homozygosity for different alleles of a given locus in different individuals or heterozygosity for the locus. The average genetic diversity for the groups of cultivars and genitors was 0.605 and 0.660, respectively, with no genetic differentiation (F-ST) between these groups. Although similar estimates of expected heterozygosity were observed when the cultivars were grouped by release date, a greater number of private alleles was observed in the most recent cultivars. The genetic differentiation among cultivars originating from different institutions was not different from zero (F-ST = 0.01). The molecular profile database derived from these analyses may increase the statistical power of genetic estimates and may be incorporated into breeding programs for common bean. Furthermore, the profiles obtained for the different cultivars may be used as molecular descriptors to complement traditional descriptors used in distinctiveness, uniformity and stability tests, thereby improving the traceability of samples and their derivatives and helping to protect the intellectual property rights of breeders.
