Sorghum grain yield can be significantly affected by climatic changes, especially drought and high temperature. The purpose of this study was to evaluate hybrids of grain sorghum grown under normal irrigation conditions or water stress in order to select those likely to be more tolerant of drought. Forty-nine hybrids were grown in a randomized block design experiment, with three replications. T...

The completed rice genome sequence will accelerate progress on the identification and functional classification of biologically important genes and serve as an invaluable resource for the comparative analysis of grass genomes. In this study, methods were developed for sequence-based alignment of sorghum and rice chromosomes and for refining the sorghum genetic/physical map based on the rice gen...

Total mixed rations containing conventional forage sorghum, brown midrib (bmr)-6 forage sorghum, bmr-18 forage sorghum, or corn silage were fed to Holstein dairy cows to determine the effect on lactation, ruminal fermentation, and total tract nutrient digestion. Sixteen multiparous cows (4 ruminally fistulated; 124 d in milk) were assigned to 1 of 4 diets in a replicated Latin square design wit...

Introduction Sudan grass is one of the most important forage crops in the Rio Grande Valley, Texas. Growth is luxuriant and rapid, and the high yields suggest that the nutrients in the soil are eminently satisfactory for the growth of this species. Repeated cuttinigs may be made, often at intervals as short as 8 to 10 days, until 3 to 10 crops have been harvested. The leaves from the latter cro...
