Southwest cotton farmers will have new varieties to choose as they plan for the 2008 crop, but they’ll find some familiar names in different places after mergers and acquisitions the past year moved old standard seed labels to new companies.

Stoneville cottonseed, for instance, now comes from FiberMax. NexGen varieties are part of Americot offerings. And Delta and Pine Land is now part of Monsanto.

Regardless of the transitions, however, farmers will benefit from many new Roundup Ready Flex and Liberty Link varieties, more Bollgard II offerings and improved packages for yield and fiber quality.

Below are some of the new varieties adapted to Southwest (Texas, Oklahoma, New Mexico, and Kansas) growing conditions. The seed companies provide variety information.
