Cotton is the most important natural textile fiber in the world, as well as a major source of oil and protein. Within the LSU Agricultural Center, the Cotton Breeding and Genetics Program seeks to develop improved germplasm and variety that addresses the needs of Louisiana cotton producers in particular and the broader market as well. Major focal points are yield and fiber quality. Fiber yield, per se, is the largest factor affecting profitable production. Improvement may be enhanced by focusing on yield components, their aggregate, as well as stability across environments. As spinning technologies improve, the many components of fiber quality have become increasingly important. New analytical methods to assess fiber quality and end-product prediction tools are being researched.
Grain sorghum, due to its low production cost, drought resistance, and tolerance to less than optimal soil conditions has seen renewed interest in the Mid-South and Southeast. Specifically in Louisiana, the shallow hardpan soils of the northeastern part of the state are particularly susceptible to drought conditions and grain sorghum is an attractive fit. Furthermore, as a rotational crop, grain sorghum has value in managing weeds by rotating herbicide chemistry, in managing nematodes that attack cotton and soybeans, and in improving soil properties. Constraints to production frequently noted in Louisiana include aphids and anthracnose and are research objectives.
