Evaluation of the potential of lines and hybrids of biomass sorghum
Silva, Michele Jorge da; Carneiro, Pedro Crescêncio Souza; Carneiro, José Eustáquio de Souza; Damasceno, Cynthia Maria BorgesMutant genotypes of biomass sorghum for low lignin - bmr (brown midrib) and sensitive to photoperiod are interesting for the production of second-generation ethanol. This research aimed to estimate the combining ability between lines A and R of biomass sorghum, both carrying the bmr-6 allele, for bioenergy potential. Three male-sterile lines (A) and ten fertility restorative lines (R) were used, generating 30 h...
The genetic architecture of phosphorus efficiency in sorghum involves pleiotrop...
Bernardino, Karine C.; Pastina, Maria Marta; Menezes, Cícero B.; Sousa, Sylvia M. de; Maciel, Laiane S.; Carvalho Jr., Geraldo; Guimarães, Claudia T.Phosphorus (P) fixation on aluminum (Al) and iron (Fe) oxides in soil clays restricts P availability for crops cultivated on highly weathered tropical soils, which are common in developing countries. Hence, P deficiency becomes a major obstacle for global food security. We used multi-trait quantitative trait loci (QTL) mapping to study the genetic architecture of P efficiency and to explore the importance of ro...

Ribeiro, Carlos Alexandre Gomes; Pádua, José Maria Villela; Dias, Kaio Olímpio das Graças; Pastina, Maria Marta; Souza, João Cândido deIn maize, the fungi that cause Fusarium ear rot result not only in decreased grain yield and quality, but also grain contamination by fumonisin. This study investigated the inheritance of fumonisin contamination resistance (FCR) in tropical maize, based on a multi-environment trials diallel analysis via mixed models. For this purpose, based on 13 inbred lines, single-cross hybrids were created and assessed in t...
Phenotypic and molecular characterization of sweet sorghum accessions for bioen...
Silva, Michele Jorge da; Pastina, Maria Marta; Souza, Vander Fillipe de; Schaffert, Robert Eugene; Carneiro, Pedro Crescêncio SouzaSweet 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 pro...
