We analyzed productivity data obtained from experiments on grain sorghum conducted in 7 locations of its cultivation in Brazil. A total of 25 hybrids were analyzed, of which 22 were pre-commercial and 3 were cultivars. The Wricke and Purchase et al. methods were highly consistent in identifying individuals with low contributions to genotype x environment interactions. The Lin and Binns method p...

Sorghum (Sorghum bicolor L. Moench) is mainly grown in the Great Plains region of United States, with state Kansas as premier cropland for its cultivation. Over time, improvements sorghum have been related to genetic and management interactions, however, scarcity information on grain filling dry down processes reported. This study characterizes dynamics hybrids different released years. Field t...

Meloidogyne chitwoodi race 1 reproduced on Piper sudangrass (Sorghum bicolor (L.) Moench), 332 (sudangrass hybrid), and P855F and P877F (sorghum-sudangrass hybrids), but failed to reproduce efficiently on Trudan 8, Trudex 9 (sudangrass hybrids), and Sordan 79, SS-222, and Bravo II (sorghum-sudangrass hybrids). Meloidogyne chitwoodi race 2 behaved similarly and reproduced more efficiently on Pip...

Sorghum breeding programs are based predominantly on developing homozygous lines to produce single cross hybrids, frequently with relatively narrow genetic bases. The adoption of complementary strategies, such as diversity study, enables a broader vision the structure germplasm. purpose this study was evaluate sorghum using analysis, principal components (PC) and clustering analyses. A total 16...

Miscanthus sacchariflorus is a fast-growing C(4) perennial grass that can naturally hybridize with M. sinensis to produce interspecific hybrids, such as the sterile triploid M.× giganteus. The creation of such hybrids is essential for the rapid domestication of this novel bioenergy crop. However, progress has been hindered by poor understanding of the environmental cues promoting floral transit...

Sorghum is a tropical grass grown primarily in semiarid and drier parts of the world, especially areas too dry for corn. Sorghum production also leaves about 58 million tons of by-products composed mainly of cellulose, hemicellulose, and lignin. The low lignin content of some forage sorghums such as brown midrib makes them more digestible for ethanol production. Successful use of biomass for bi...

The aim of this study was to study the agronomic traits of different Sorghum bicolor (L.) Moench hybrids for silage productionin semiarid conditions. It was a 1-year evaluation conducted in a randomized block design with 24 treatments and three replicates. The treatments were sorghum hybrids developed by the breeding program of "Embrapa Milho e Sorgo" (Brazilian Agricultural Research Corporatio...

The objective of this study was to further the understanding of the effects of dietary protein and energy supplements on growth, performance, feed intake and grass forage digestibility in growing meat goat wethers. In Experiment 1, an 18% CP complete goat pellet was offered alone (control diet, C) or added (+), or not, as supplement to three grass hays (coastal bermudagrass, CB; Tifton 85 bermu...

The r1 and b1 genes of maize, each derived from the chromosomes of two progenitors that hybridized >4.8 million years ago (MYA), have been a rich source for studying transposition, recombination, genomic imprinting, and paramutation. To provide a phylogenetic context to the genetic studies, we sequenced orthologous regions from maize and sorghum (>600 kb) surrounding these genes and compared th...

Striga hermonthica is a widely spread root parasitic weed on cereals in Sub Saharan Africa including Sudan. The most important hosts comprise sorghum, millet and sugar cane. Host specificity and existence of two distinct strains on sorghum and millet were previously reported. Reports on a third strain specific to maize are controversial. The present study was undertaken to investigate anatomica...
