“…One motivating factor for this renewed interest is the historical success that has been achieved from multiple uses of S. spontaneum germplasm to improve sugarcane for sugar production (Berding & Roach, 1987;Dunckelman & Breaux, 1970;Reffay et al, 2005). A second factor is the potential to exploit the wide range of adaptability displayed by S. spontaneum genotypes to increase production outside the traditional canegrowing regions by selecting genotypes more closely related to S. spontaneum with little or no constraints on fiber content (Anderson et al, 2016;Claudio et al, 2015;Kimbeng et al, 2015;Ramos et al, 2017;Santchurn et al, 2012Santchurn et al, , 2014Tew & Cobill, 2008;Wang et al, 2008). This study attempts to provide preliminary information that would guide future utilization of similar types of populations and experiments to develop relevant germplasm for use in variety development for both industries.…”

Sugarcane production benefitted from useful genes imparted from Saccharum spontaneum L. Interspecific hybrids were evaluated for sugar and biomass traits in three environments, including two plants and one ratoon crop. The objective was to estimate genetic parameters for traits in this population and to develop appropriate breeding strategies and germplasm for use in variety development in both the sugar and bioenergy industries. Heritability was highest with all three environments considered; however, the increase was minimal compared with estimates from the first ratoon crop suggesting resources will be better spent selecting in the first ratoon crop. Significant differences (p < 0.05) found among families for sucrose content related traits, warrants selecting first among families before selecting among genotypes within families for these traits. The same was not true for cane yield and cane yield components. Heritability was low to moderate (> 0.3 < 0. 47) for cane yield its components, and high (> 0.7) for all other traits suggesting early selection in small plots could emphasize sucrose content related traits. Selecting intensely for a highly heritable trait in one stage can influence genetic variation of another trait in subsequent stages. Therefore, multivariate selection methods were employed which identified groups of genotypes with characteristics distinct to both industries. The S. spontaneum parents dominated trait variation in the hybrid population. Consequently, whereas genotypes with potential for the sugar industry would have to undergo rounds of backcrossing to recover good sugar characteristics, genotypes with immediate potential in the bioenergy industry were easily identified in this population.This article is protected by copyright.

“…The Inter‐University Network for the Development of the Sugar‐Energy Sector (RIDESA: Rede Interuniversitária para o Desenvolvimento do Setor Sucroenergético) initiated a hybridization program involving S. spontaneum , S. robustum , and commercial cultivars ( Saccharum ssp.) to develop clones with fiber content exceeding 17% while preserving the existing 13% sucrose content (Ming et al., 2006; Ramos, Brasileiro, Kist, et al., 2017; Ramos, Brasileiro, Silveira, et al., 2017; Silveira et al., 2015). The species S. spontaneum and S. robustum exhibit high resistance to pests and diseases, robust vigor, elevated fiber content, and a high tillering capacity (Carvalho‐Netto et al., 2014; Matsuoka et al., 2014).…”

The burgeoning cellulosic ethanol industry necessitates advancements in enzymatic saccharification, effective pretreatments for lignin removal, and the cultivation of crops more amenable to saccharification. Studies have demonstrated that natural inhibitors of lignin biosynthesis can enhance the saccharification of lignocellulose, even in tissues generated several months post‐treatment. In this study, we applied daidzin (a competitive inhibitor of coniferaldehyde dehydrogenase), piperonylic acid (a quasi‐irreversible inhibitor of cinnamate 4‐hydroxylase), and methylenedioxy cinnamic acid (a competitive inhibitor of 4‐coenzyme A ligase) to 60‐day‐old crops of two conventional Brazilian sugarcane cultivars and two energy cane clones, bred specifically for enhanced biomass production. The resultant biomasses were evaluated for lignin content and enzymatic saccharification efficiency without additional lignin‐removal pretreatments. The treatments amplified the production of fermentable sugars in both the sugarcane cultivars and energy cane clones. The most successful results softened the most recalcitrant lignocellulose to the level of the least recalcitrant of the biomasses tested. Interestingly, the softest material became even more susceptible to saccharification.
