Sorghum bicolor (L.) Moench is a multipurpose crop worldwide, and it is used as a source of food, fodder, feed, and fuel. It is currently considered a promising alternative crop for generating bioenergy from sugar and lignocellulosic biomass. Sweet sorghum accumulates soluble sugar in its juicy stalk, being more appropriate for first-generation ethanol production, while biomass sorghum can be used for second-generation ethanol or bioelectricity production. For the development of superior sorghum cultivars dedicated to grain or biomass usage, breeding programs usually focus on several traits related to bioenergy, most of them exhibiting a quantitative inheritance. The genetic architecture and the environmental effects involved in the phenotypic expression of major sorghum traits are key factors to improve sorghum as a grain or bioenergy crop. In this context, understanding the availability of sorghum genetic resources, diversity, and molecular information at the RNA and DNA level is fundamental to perform effective selection strategies in sorghum. Population genomics research is providing key insights into genome structure, genomic variation, genetic diversity and population structure, origin and domestication history, and genetic architecture of adaptation to local climate as well as genomic-assisted selection and breeding in sorghum. In this chapter, we thoroughly discuss the progress made on these population genomics and molecular breeding aspects in sorghum and present future perspectives. Substantial research progress has been made on understanding the genetic basis of economically important sorghum traits through the identification of QTLs via linkage mapping and genome-wide association study (GWAS). Genomic selection or genome-wide selection has a great potential for increasing genetic gains in sorghum breeding programs for bioenergy and other traits. MenosSorghum bicolor (L.)

ABSTRACT - The objective of this work was to evaluate the nutritional value of silages from tall-sized and dwarf elephant grass (Pennisetum purpureum) genotypes, intercropped or not with butterfly pea (Clitoria ternatea). The experiment was performed in randomized complete blocks, in a 4x2 factorial arrangement (four genotypes × two cropping systems). The genotypes intercropped or not with butterfly pea were: IRI-381 and Elephant B, tall sized; and Taiwan A-146 2.37 and Mott, dwarf. Forage was harvested 60 days after regrowth. In the silage from Mott grass intercropped with butterfly pea, lower contents of lignin (78.1 g kg-¹), neutral detergent fiber (636.0 g kg-¹), and neutral detergent insoluble protein (13.15 g kg-¹), besides a greater dry matter recovery (873.3 g kg-¹), were observed. The silage from Taiwan A-146 2.37 intercropped with the legume showed a greater crude protein content (136.1 g kg-¹). In both silages, the ammonia nitrogen contents were quite reduced (26.4 g kg-¹). However, greater residual water-soluble carbohydrate contents were observed in the silages from the intercrop (1.85 mg g-¹) and from the Mott grass monocrop (1.51 mg g-¹). Moreover, there was a lower in vitro dry matter digestibility (676.7 g kg-¹) for the silage from the intercrop. Dwarf genotypes increase the nutritional value of elephant grass silage, compared with the tall-sized ones. Intercropping with butterfly pea improves silage fermentation characteristics, despite reducing its digestibility. Therefore, the ensilage of dwarf Mott elephant grass intercropped with butterfly pea shows more promising results. RESUMO - O objetivo deste trabalho foi avaliar o valor nutritivo de silagens de genótipos anões e altos de capim-elefante (Pennisetum purpureum), consorciados ou não à cunhã (Clitoria ternatea). O experimento foi realizado em delineamento de blocos ao acaso, em arranjo fatorial 4x2 (quatro genótipos × dois sistemas de plantio). Os genótipos consorciados ou não à cunhã foram: IRI-381 e Elefante B, de porte alto; e Taiwan A-146 2.37 e Mott, anões. A forragem foi colhida após 60 dias de rebrota. Na silagem do capim Mott consorciado à cunhã, foram observados menores teores de lignina (78,1 g kg-¹), fibra em detergente neutro (636,0 g kg-¹) e proteína insolúvel em detergente neutro (13,15 g kg-¹), além de maior recuperação da matéria seca (873,3 g kg-¹). A silagem de Taiwan A-146 2.37 cultivado em consórcio com a leguminosa apresentou maior teor de proteína bruta (136,1 g kg-¹). Em ambas as silagens, os teores de nitrogênio amoniacal foram bastante reduzidos (26,4 g kg-¹). No entanto, maiores teores residuais de carboidratos solúveis em água foram observados nas silagens do consórcio (1,85 mg g-¹) e do capim Mott em monocultivo (1,51 mg g-¹). Além disso, houve menor digestibilidade in vitro da matéria seca (676,7 g kg-¹) na silagem do consórcio. Os genótipos anões aumentam o valor nutricional da silagem de capim-elefante, comparados aos de porte alto. O consórcio com a cunhã melhora as características fermentativas da silagem, apesar de reduzir a sua digestibilidade. Portanto, a ensilagem do capim anão Mott consorciado à cunhã apresenta resultados mais promissores.
