“…At the same time, this plant has a high photosynthetic efficiency and can form a powerful biomass in a short time. Due to its biological characteristics, it is an alternative source of biofuels and sugar-containing products based on the processing of sugar sorghum stems [3][4][5]. Therefore, the creation of new highly productive varieties and hybrids of sorghum intended for use as an alternative raw material in the production of bioethanol is a promising direction in breeding.…”

Currently, the most promising direction of breeding is the creation of F1 hybrids of sugar sorghum, based on the identification and selection of parental forms with high combinational ability. The source material and F1 hybrids were grown in the arid conditions of the Saratov Right Bank (Russia): the hydrothermal coefficient during the growing season was 0.68. The evaluation of the combinational ability of crossing components was carried out using the topcross method. As a result of the tests, the L-52/13 line was identified with high GCA effects (15.71), and the highest SCA dispersions were found in the Saratovskoe 90 variety and the L-39/12 line (91.80-189.27). It was found that the type of sterile cytoplasm of iso-nuclear CMS-lines had a significant impact on the manifestation of SCA in terms of biomass yield: higher dispersion indicators were noted in 9E Zheltozernoye 10 (36.66). Genes with an additive effect are involved in the genetic control of this trait in paternal forms, and non-additive genes in maternal forms. In addition, each hybrid combinationwas observed with superdomination: the coefficient of phenotypic dominance varied from 2.01 to 18.91. It is advisable to use the obtained information in the hybridization of sugar sorghum to obtain high-heterosis hybrids.

“…Biomass sorghum [Sorghum bicolor (L.) Moench] is a crop with a high potential as a biomass source for bioenergy generation, both for obtaining second generation ethanol (Amaducci et al, 2000;Davila-Gomez et al, 2011;Silva et al, 2018Silva et al, , 2020 and for the energy cogeneration by direct biomass burning (Bennett & Anex, 2009;Zegada-Lizarazu & Monti, 2012).…”

The objective of this work was to evaluate the potential of computational intelligence and canonical variables for studies on the genetic diversity between biomass sorghum (Sorghum bicolor) genotypes. The experiments were carried out in the experimental field of Embrapa Milho e Sorgo, in the municipalities of Nova Porteirinha and Sete Lagoas, in the state of Minas Gerais, Brazil. The following traits were evaluated: days to flowering, plant height, fresh biomass yield, total dry biomass, and dry biomass yield. The study of genetic diversity was performed through the analysis of canonical variables. For the recognition of the organization pattern of genetic diversity, Kohonen’s self-organizing map was used. The use of canonical variables and a self-organizing map were efficient for the study of genetic diversity. The application of computational intelligence using a self-organized map is promising and efficient for studies on the genetic diversity between biomass sorghum genotypes.

“…Sorghum bicolor (L.) Moench is a crop that has high potential to be used for bioenergy generation. The crop has a short cycle (150-180 days), wide adaptability, seed propagation, fully mechanized production, and high productivity, which reaches 150 t/ha of green mass (da Silva et al 2020;Oliveira et al 2019). Other advantages include its tolerance to drought, an established agricultural production system, good aptitude for tropical and temperate regions and its biomass can be used in direct combustion (second-generation bioethanol) to generate energy (Parrella et al 2010).…”

Sorghum bicolor (L.) Moench is a crop that has high potential to be used for bioenergy generation. The objective of this study was to introgression of the bmr6 allele in elite lines of biomass sorghum and to obtain experimental ''brown midrib'' hybrids. Three genetic materials belonging to the Embrapa Maize and Sorghum Breeding Program were used. Two backcross programs were conducted separately, in which the CMSXS170 line was the donor of the bmr6 allele and the CMSXS652 and IS23777 lines were the recurrent ones. Through molecular markers specific for the bmr6 allele, the assisted selection was utilized for the brown midrib characteristic in the BC 1 F 1 and BC 2 F 1 generations. Polymorphic SNP markers were distributed throughout the genome of sorghum to accelerate the recovery of the recurrent genome. After the confirmation of the bmr genotypes, the lines were crossed with line A (female), to obtain the hybrid seeds and evaluated under field conditions. As result, it was possible to perform the introgression of the bmr6 allele in lines of biomass sorghum. The SNPs markers were efficient in identifying individuals with a higher rate of recurrence of the recurrent genome. Experimental ''brown midrib'' hybrids were obtained and demonstrated satisfactory potential for bioenergy production.
