Climatic change derived from greenhouse gases (GHG) anthropogenic emissions consists in one of the main concerns of public policy makers. In Brazil, agricultural activities and livestock are responsible for 23% of gross GHG emissions, and land use and soil management are the main factors that drive these emissions levels. Soil carbon is mainly stocked as soil organic matter (SOM), and SOM stocks are related to clay content in soil and soil management. In order to improve the monitoring of these factors, we propose the use of ASTER TIR images data to map quartz, phyllosilicated clays, and non-photosynthetically active vegetation (NPAV) in order to assess remote sensing techniques to large-scale mapping of environments with greater or less soil carbon accumulation. We used thermal bands ratios to get quartz, phyllosilicated clays, and NPAV image fractions, that were compared to ASTER VNIR images and to the soil classes map of the study area. Results show that areas with higher values in quartz image fraction are related to bare soils areas in quartz-enriched soils. Higher values in phyllosilicates image fraction are related to bare soils areas with clay soils and higher values in NPAV image fraction are consistent to the vegetation activity throughout the study area, including crop residues areas detected in large-scale farms. |

Sweet sorghum [Sorghum bicolor (L.) Moench] is a type of cultivated sorghum characterized by the accumulation of high levels of sugar in the stems and high biomass accumulation, making this crop an important feedstock for bioenergy production. Sweet sorghum breeding programs that focus on bioenergy have two main goals: to improve quantity and quality of sugars in the juicy stem and to increase fresh biomass productivity. Genetic diversity studies are very important for the success of a breeding program, especially in the early stages, where understanding the genetic relationship between accessions is essential to identify superior parents for the development of improved breeding lines. The objectives of this study were: to perform phenotypic and molecular characterization of 100 sweet sorghum accessions from the germplasm bank of the Embrapa Maize and Sorghum breeding program; to examine the relationship between the phenotypic and the molecular diversity matrices; and to infer about the population structure in the sweet sorghum accessions. Morphological and agro-industrial traits related to sugar and biomass production were used for phenotypic characterization, and single nucleotide polymorphisms (SNPs) were used for molecular diversity analysis. Both phenotypic and molecular characterizations revealed the existence of considerable genetic diversity among the 100 sweet sorghum accessions. The correlation between the phenotypic and the molecular diversity matrices was low (0.35), which is in agreement with the inconsistencies observed between the clusters formed by the phenotypic and the molecular diversity analyses. Furthermore, the clusters obtained by the molecular diversity analysis were more consistent with the genealogy and the historic background of the sweet sorghum accessions than the clusters obtained through the phenotypic diversity analysis. The low correlation observed between the molecular and the phenotypic diversity matrices highlights the complementarity between the molecular and the phenotypic characterization to assist a breeding program.
