Bayer CropScience cottonseed brands FiberMax and Stoneville were planted on a majority — 50.2 percent — of U.S. cotton acres in 2010, noted Jeff Brehmer, U.S. FiberMax and Stoneville marketing manager. Brehmer added that four varieties, FM 9058F, FM 9160B2F, FM 9063B2F and FM1740B2F accounted for more than one-fourth of all U.S. planted acres in 2010.

Bayer CropScience is evaluating experimental varieties for yield and fiber quality characteristics in its cotton breeding program and cotton agronomic performance trials. These varieties include new proprietary traits from Bayer CropScience, such as GlyTol glyphosate-tolerant technology and stacked varieties with both GlyTol and LibertyLink traits.

Bayer CropScience will commercialize its GlyTol glyphosate-tolerant technology in FiberMax varieties for Southwest cotton growers for the 2011 season.

According to Brehmer, two high-performing FiberMax varieties containing GlyTol technology will be available in 2011: FM 9101GT and FM 9103GT. Both are well-adapted to the High Plains and Rolling Plains of the Southwest and have exhibited excellent yield potential.

Bayer CropScience is also testing four new LibertyLink, Bollgard II varieties adapted for the Mid-South and Southeast. Additional information will be released in January 2011. Visit Bayer for more information. Here are new FiberMax and Stoneville varieties for 2011:

FiberMax

FM 1773LLB2 — offers the newest FiberMax germplasm in a medium maturity LibertyLink cotton variety with the insect protection of Bollgard II and tolerance to Ignite herbicide. It is well-adapted to East Texas, the Mid-South, Southeast and Mid-Atlantic regions, and provides excellent fiber quality with high yield potential. The LibertyLink trait provides excellent crop safety with use of Ignite herbicide.

FM 9101GT — this new early/medium maturity variety is well-adapted to the High Plains and Rolling Plains of the Southwest and has exhibited excellent yield potential, storm tolerance and has a very good fiber package. GlyTol offers a wide application window and optimal crop tolerance for over-the-top applications of glyphosate. An aggressive, timely defoliation program is recommended to maximize yield potential and fiber quality.

FM9103GT — This early maturity variety is well-adapted to the High Plains and Rolling Plains of the Southwest and has exhibited excellent yield potential and a very good fiber package. GlyTol offers a wide application window and optimal crop tolerance for over-the-top applications of glyphosate.

Stoneville

ST 5288B2F — is a medium-maturing Roundup Ready Flex/Bollgard II variety. It is well-adapted for the Southwest, Mid-South, Southeast and Mid-Atlantic cotton growing areas. It has excellent seedling vigor and sets a high level of fruiting nodes. ST 5288B2F has exhibited excellent yield potential and good fiber quality across the Cotton Belt and is well-suited for irrigated and dryland conditions. An aggressive, timely defoliation program is recommended to maximize yield potential and fiber quality.

ST 5458B2RF — is a new medium maturity Roundup Ready Flex/Bollgard II variety offering root-knot nematode tolerance. It is easy-to-manage with moderately aggressive growth. It performs well in the West, Southwest, Mid-South, Southeast and mid-Atlantic regions.
