Performance Of New Cotton Varieties In The North Delta

   The release of cotton varieties with the latest biotechnology traits has researchers and producers scrambling to find varieties that perform as well as first generation biotechnology trait varieties. Beyond obvious yield goal, intangible benefits of these new technologies are driving their adoption. The increased flexibility for weed management and the ability to use a natural refuge with Roundup Ready Flex and two gene Bt traits has producers looking towards these new varieties for time savings and reductions in input costs. In this presentation we investigate the performance of recently released cotton varieties in the North Delt a states of Arkansas, Missouri, and Tennessee.
   While yields for these new cotton varieties have lacked stability, fiber quality is typically equal to or better than the first generation biotech cotton varieties. To better understand performance of these new varieties the presentation will focus on yield stability models and fiber quality evaluations for several of the more popular cotton varieties grown in the North Delta region.
