in order to study of drought tolerance in advanced grain sorghum lines, an experiment was conducted in a split-plot on randomized complete block design with three replications in experimental field of seed and plant improvement institute, karaj, iran during 2009-2010. irrigation regimes were assigned to main plots at three levels including normal irrigation (i1=60mm), moderate stress (i2=120mm)...

Grain sorghum [Sorghum bicolor (L.) Moench) typically produces larger seeds than sudangrass [S. bicolor, formerly S. sudanense (Piper) Stapf]; and grain sorghum seedlings are higher in hydrocyanic acid potential (HCN-p) than sudangrass seedlings. Previous studies have shown a seed-parent effect on seed weight and HCN-p in reciprocal F, hybrids of sorghum X sudangrass. This study was conducted t...

Sorghum (Sorghum bicolor L. Moench) is a native grass species of the arid and semi-arid regions of Africa (Kimber 2000). Sorghum is a genetically diverse crop and contains some genotypes that have a pigmented testa and therefore contain tannins (Rooney et al 1980; Rooney and Miller 1982). Such lines have the dominant B1_B2_ genes and are the only sorghum types with tannins (Blakeley et al 1979)...

is less indicative of phenotype since iodine binding is reduced in lines with corneous endosperm (Cagampang Visual classification of sorghum [Sorghum bicolor (L.) Moench] and Kirleis, 1985). However, such sorghum starch can grain for the waxy phenotype is subjective and can be confounded be made more amenable to iodine staining by gelatinizaby genetic background, maturity, environment, and expe...

Funnell-Harris, D. L., and Pedersen, J. F. 2011. Presence of Fusarium spp. in air and soil associated with sorghum fields. Plant Dis. 95:648-656. Sorghum grain, valuable for feed, food, and bioenergy, can be colonized by several Fusarium spp.; therefore, it was of interest to identify possible sources of conidia. Analysis of air and soil samples provided evidence for the presence of propagules ...

In order to leverage novel sequencing techniques for cloning genes in eukaryotic organisms with complex genomes, the false positive rate of variant discovery must be controlled for by experimental design and informatics. We sequenced five lines from three pedigrees of ethyl methanesulfonate (EMS)-mutagenized Sorghum bicolor, including a pedigree segregating a recessive dwarf mutant. Comparing t...

Sorghum [Sorghum bicolor (L.) Moench] grain yield is severely affected by abiotic and biotic stresses during post-flowering stages, which has been aggravated by climate change. New parental lines having genes for various biotic and abiotic stress tolerances have the potential to mitigate this negative effect. Field studies were conducted under irrigated and dryland conditions with 128 exotic ge...
