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.

RESUMO - Foram comparados os modelos de regressão linear, quadrética e exponencial para estimar o número de horas de frio igual ou inferior a 7°C. As equações propostas são funções de temperaturas médias mensais ou médias das mínimas, medidas à sombra. As equações de regresso quadrática ajustaram-se melhor aos dados e permitem obter estimativas mais precisas. A partir de dados comuns, como as normais de temperaturas médias e médias das mínimas, pode-se estimar horas de frio para locais desprovidos desta informação, no Estado do Espírito Santo. ABSTRACT - Linear, quadratic and exponencial retression models were compared to estimate the number of hours with temperature equal or below 7°C. The studied equations were functions of the average and minimum monthly temperatures. The quadratic regression equation was found to be the most adequate. Based on common data as the minimum and average temperatura, the nurnber. of chilling hours could be estimated in a given area of the State of Espirito Santo without actual date. |
