Storm resistance is a concern for cotton growers across many regions. Seed companies have made great strides in developing cotton varieties with better storm resistance that are more likely to survive damaging weather prior to harvest without considerable lint loss. In regions such as Texas and Oklahoma, storm resistance is a factor in choosing varieties to plant.
Tight or Loose in the Burr
Stripper-type cotton varieties were once about all that was grown in the western regions. As seed companies began breeding more picker-type varieties, improving yield potential and fiber quality along the way, harvest equipment also improved. Today, many growers in Texas and Oklahoma plant picker-type varieties and harvest with spindle picker machines, having abandoned the stripper harvesters for better picking quality and efficiencies. Just because they are picker-type varieties, it does not mean they have poor storm resistance.
Growers should inquire about the storm resistance of any variety on their potential planting list. If choosing a variety with low storm resistance, plan and budget ahead for a good harvest aid program that will achieve an early harvest. Good storm-resistance data are now being provided by most companies, and Extension programs also evaluate this characteristic in their research variety trials.
Know the Ratings
Product ratings help seed companies position their varieties under the right conditions to meet the growers’ needs, field conditions and management practices for the most successful outcome. Categories for cotton variety ratings include agronomic and seed characteristics, maturity, fiber quality averages and stress tolerance.
Deltapine® brand varieties are rated for the very reasons stated above. The general product rating scale runs from 1 to 9, with 1 representing excellent and 9 meaning poor. Other characteristics have individualized ratings, meaning they are relevant within comparisons to other Deltapine varieties only.
Storm resistance helps to describe how tight or loose cotton fibers can be in the boll of a particular variety, and is evaluated in our breeder evaluations, variety trials and the New Product Evaluator (NPE) Program before commercialization. Deltapine storm resistance ratings are based on a 1 to 9 scale, with 1 being tight in the burr like a stripper-type variety, and 9 being loose.
You can find Deltapine variety storm resistance ratings on the seed bags and lots themselves.
