RESUMO - O objetivo deste trabalho foi avaliar as características morfogênicas do colmo principal de genótipos de sorgo sacarino, em diferentes espaçamentos entrelinhas e épocas de semeadura. O experimento foi conduzido em Santa Maria-RS, em delineamento experimental de blocos ao acaso em esquema trifatorial (2x2x3), com dois genótipos de sorgo sacarino (BRS 506 e Fepagro 19), dois espaçamentos entrelinhas (0,50 m e 0,70 m) e três épocas de semeadura (outubro, novembro e dezembro), quatro repetições e dois anos de cultivo. Foram avaliadas a taxa de alongamento das folhas, o número final de folhas no colmo, a taxa de surgimento de folha, filocrono e taxa de elongamento de colmo. As variáveis não apresentaram interação tripla significativa entre genótipo, espaçamento de entrelinhas e época de semeadura. O genótipo BRS 506 apresentou número de folhas acumuladas, taxa de alongamento de folhas nas épocas de semeaduras constante. O atraso na época de semeadura resulta em menor número de folhas acumuladas e taxa de elongação do colmo para o Fepagro 19. O filocrono para o espaçamento entrelinhas 0,70 m é inferior ao de 0,50 m. Os genótipos estudados estão aptos para a produção na região, desde que a semeadura ocorra no mês de outubro. Palavras-chave: alongamento foliar, filocrono, graus-dia, índice Haun, Sorghum bicolor. LEAF MORPHOLOGY OF SWEET SORGHUM CULTIVATED IN DIFFERENT ROW SPACINGS AND SOWING DATES ABSTRACT - The objective of this work was to evaluate the morphogenic characteristics of the main stem of sweet sorghum genotypes in different spacing between lines and sowing times. The experimental was carried out in a randomized complete block design in a trifactorial scheme (2x2x3), with two sweet sorghum (BRS 506 and Fepagro 19), two spacing between lines (0.50 m and 0.70 m) and three sowing seasons (October, November and December), four replications and two years of cultivation. The leaf elongation rate, the final number of leaves in the stem, the leaf appearance rate, phyllochron and shoot elongation rate were evaluated. The variables did not present significant triple interaction between genotype, spacing between rows and sowing time. The genotype BRS 506 presented a number of accumulated leaves, leaf elongation rate at constant sowing times. The delay in sowing seasons results in a lower number of accumulated leaves and the elongation rate of the stem for genotype Fepagro 19. The phyllochron for the 0.70 m line spacing is less than 0.50 m. The genotypes studied are suitable for production in the region, as long as sowing occurs in October.Keywords: leaf elongation, phyllochron, degree-days, Haun index, Sorghum bicolor.

The fossil energy sources used in the world are gradually decreasing and limited. Fossil fuels cause environmental pollution, and the unit price is constantly increasing. For this reason, demand for cheaper and renewable energy sources that do not pollute the environment is increasing day by day. The sweet sorghum plant has attracted attention in recent years with its high biomass yield, sugar content and bioethanol yield. In this study, it was aimed to determine the bio-fuel potential of some sweet sorghum genotypes in semi-arid climatic conditions. The experiment was set up in randomized complete block design with 4 replicates. Research was carried out in 2015 under Harran Plain (36o 42’ N and 38o 58’ E) second crop conditions, Sanliurfa, Turkey. In the study 49 genotypes of sweet sorghum were used. Stalk yield, juice yield, syrup yield, brix, sugar yield and theoretical ethanol yield were determined in the study. Significant differences were found between the genotypes for tested characteristics (P≤0.01). Stalk yield ranged from 7110.0 kg da-1 to 24262.5 da-1, juice yield from 2550.0 L da-1 to 12187.5 L da-1, syrup yield from 291.4 L da-1 to 2242.5 L da-1. Also, brix value varied between %7.0 and %18.87, sugar yield between 247.7 da-1 and 1906.1 da-1, Theoretical ethanol yield between 131.9 L da-1 and 1014.8 L da-1. Considering to stalk yield, juice and syrup yield, brix, sugar yield and theoretical ethanol yield; Nebraska sugar, Topper 76, Smith, M81E and Corina genotypes were found as the best. As a result of research, 21 genotypes with better performance than the others were selected for further studies.

The genotype and environment interaction influences the selection criteria of sorghum (Sorghum bicolor) genotypes. Eight sweet sorghum genotypes were evaluated at five different locations in two growing seasons of 2014. The aim was to determine the interaction between genotype and environment on cane, juice, and ethanol yield and to identify best genotypes for bioethanol production in Kenya. The experiments were conducted in a randomized complete block design replicated three times. Sorghum canes were harvested at hard dough stage of grain development and passed through rollers to obtain juice that was then fermented to obtain ethanol. Cane, juice, and ethanol yield was analyzed using the additive main effect and multiplication interaction model (AMMI) and genotype plus genotype by environment (GGE) biplot. The combined analysis of variance of cane and juice yield of sorghum genotypes showed that sweet sorghum genotypes were significantly (P<0.05) affected by environments (E), genotypes (G) and genotype by environment interaction (GEI). GGE biplot showed high yielding genotypes EUSS10, ACFC003/12, SS14, and EUSS11 for cane yield; EUSS10, EUSS11, and SS14 for juice yield; and EUSS10, SS04, SS14, and ACFC003/12 for ethanol yield. Genotype SS14 showed high general adaptability for cane, juice, and ethanol yield.

 RESUMO - O rendimento de cultivares de sorgo sacarino em planta de primeiro corte e na rebrota tem sido estudado para viabilizar o cultivo com menores custos de produção. Entretanto, dados qualitativos sobre a qualidade de caldo e rendimento de etanol entre safra principal e rebrota são escassos. Objetivou-se com este trabalho comparar genótipos de sorgo sacarino quanto à qualidade industrial e avaliar o efeito do tipo de colheita e biomassa processada no rendimento industrial para produção de etanol. Foi conduzido um experimento em blocos ao acaso com três repetições em esquema de parcela subdividida, sendo as parcelas constituídas por 20 genótipos de sorgo e as subparcelas pelos tipos de amostras processadas ou colheitas realizadas. Os maiores rendimentos de etanol, em termos absolutos, foram obtidos para CMSXS646 e BRS 511 na colheita de primeiro corte com colmos limpos. A utilização de colmos limpos promoveu, em média, um incremento de 13,5, 14,2, 13,4, 3,3, 7,9, 7,0, 8,0 e 16,4% para etanol, ART, ATR, umidade, ARC, Pol, °Brix, quantidade de caldo, respectivamente, e redução de 17,3% para fibra, em relação às amostras de colmos com folhas. O rendimento médio de etanol por tonelada de caldo extraído foi 28% superior no primeiro corte comparativamente à rebrota.Palavras-chave: Bioenergia, biomassa, °Brix, Sorghum bicolor.  INDUSTRIAL QUALITY AND ETHANOL YIELD OF SWEET SORGHUM GENOTYPES IN MAIN AND RATOON CROPS  ABSTRACT - The yield of sweet sorghum cultivars in first cut and ratoon crops have been studied to enable the cultivation with lower production costs. However, qualitative data on broth quality and yield of ethanol on main crop and ratoon are scarce. The aim of this work was to compare sweet sorghum genotypes regarding the industrial quality and to evaluate the effects of harvests and processed biomass types in the industrial yield for ethanol production. A randomized block design experiment was carried out with three replicates in a split plot design, being the plots composed by 20 sorghum genotypes and the subplots by the types of processed samples or harvests. The highest ethanol yields, in absolute terms, were obtained for CMSXS646 and BRS 511 in first cut with clean stalks. The use of clean stalks promoted, on average, an increase of 13.5, 14.2, 13.4, 3.3, 7.9, 7.0, 8.0 and 16.4% for ethanol, ART, ATR, moisture, ARC, Pol, ° Brix, juice amount, respectively, and reduction of 17.3% for fiber, in relation to samples with stalks and leafs. The average yield of ethanol per extracted juice ton was 28% higher in first cut compared to ratoon.Keywords: bioenergy, biomass, °Brix, Sorghum bicolor.

This study evaluated the effects of the sugarcane borer Diatraea saccharalis (Fabricius, 1794) (Lepidoptera: Crambidae) on cultivars of sweet and biomass sorghum for the selection of resistant cultivars. The present work consisted of two trials, with natural pest infestation. In the first one, 10 sweet sorghum cultivars were analyzed for the following variables: plant height, number of healthy and damaged internodes, gallery position and size, stem infestation level and soluble solids content (°Brix). In the second trial, it was analyzed 16 genotypes of high biomass sorghum, with the same variables above mentioned, in addition to the lignin, cellulose and hemicellulose contents. Among sweet sorghum genotypes evaluated, the genotype CMSXS647 stood out due to the traits: plant height, infestation level, gallery size and soluble solids content. Among the sorghum genotypes evaluated, CMSXS7030, CMSXS7012 and CMSXS7028 presented ideal characteristics for infestation level, plant height and number of lignocellulosic compounds. Such information, in addition to supporting the bioenergy sorghum breeding program, will assist in integrated pest management for sorghum cultivation.

Currently, sweet sorghum has presented great expansion of cultivation in traditional areas and new technologies sugar and alcohol sector. The aim was to to identify what agronomic traits can be used for indirect selection of genotypes with higher sugar yield. The work was conducted in the harvest 2014/2015, at Embrapa Agropecuária Oeste, in Dourados, MS. It were evaluated 25 genotypes in experimental design was a randomized block design with three replications. We evaluated the following agronomic traits: plant height, fresh mass, percentage of stem, leaves and panicles, dry mass, Brix, yield of juice and sugar. The F-test was used to check for genetic variability among genotypes. Phenotypic correlations among these traits were estimated, which are deployed through the path analysis, in direct and indirect effects, considering the yield sugar as the primary dependent variable. We observed that 92% of the variation in sugar yield was explained by the explanatory variables, value higher than in other studies and appropriate to explore the gains with indirect selection in sweet sorghum. The indirect selection based on Brix trait is the most effective way to obtain genetic progress in the sugar yield in sorghum genotypes.
