Sorghum grows throughout the world in wide-ranging environments and growing conditions. This high level of variety provides a broad genetic base from which researchers can develop desirable traits quickly and effectively.<\/p>\n<\/div>\n
\u00e2\u20ac\u0153We can look for DNA markers for specific traits within the sorghum species then apply those to breeding and seed development programs without having to borrow them from other plant species,\u00e2\u20ac\ufffd said Chad Hayes, a sorghum geneticist with the U.S. Department of Agriculture – Agricultural Research Service (USDA-ARS) in Lubbock, Texas.<\/span><\/p>\n This ability to use genetics from within the species results in targeted genetic improvements while offering a crop that can enter the marketplace without issues associated with genetically modified organisms (GMOs).<\/p>\n For USDA sorghum research, the emphasis is currently focused on drought- and cold- tolerant varieties. Demand for sorghum this marketing year has led to increased plantings, including in areas of the United States that traditionally haven\u00e2\u20ac\u2122t produced much of the crop.<\/span><\/p>\n \u00e2\u20ac\u0153We are looking into indentifying the DNA markers that contribute to drought tolerance in dry areas and researching the ability of sorghum seed to germinate in cooler conditons for the northern regions,\u00e2\u20ac\ufffd Hayes said.<\/span><\/p>\n The process for developing new drought- and cold-tolerant sorghum is the same that has been applied to other crops. <\/span><\/p>\n \u00e2\u20ac\u0153We\u00e2\u20ac\u2122ve not seen the emphasis to apply the knowledge to sorghum seed programs until recently because seed companies \u00e2\u20ac\u201c and to some extent, farmers \u00e2\u20ac\u201c did not see the potential for a return on the investment of such technology,\u00e2\u20ac\ufffd Hayes said.<\/p>\n However, a robust and energized effort by the U.S. sorghum industry, paired with rising demand for sorghum, has shifted the focus and provided support for sorghum improvements to USDA and university researchers.<\/span><\/p>\n Disease tolerance is another important consideration for genetic trait selection. The emphasis is toward seed varieties that are tolerant to disease-inducing situations throughout the growing and harvest seasons without impacting the end quality and quantity of the grain.<\/span><\/p>\n \u00e2\u20ac\u0153We know there is a strong demand for sorghum,\u00e2\u20ac\ufffd Hayes said. \u00e2\u20ac\u0153The unified effort within the sorghum industry is moving forward with technology for U.S. farmers to grow a hardy and high-yielding crop that produces a quality grain demanded by international buyers.\u00e2\u20ac\ufffd <\/span><\/p>\n","protected":false},"excerpt":{"rendered":" Sorghum grows throughout the world in wide-ranging environments and growing conditions.
