The Deltapine Class of 16 cotton varieties – announced during the 2015 New Product Evaluator (NPE) Summit in San Antonio, TX – were proven to perform by NPE farmers, who grew them in large-acre plots under their own management systems. Their evaluation and feedback were important to the selection of lines for commercial advancement. Many of them attend the summit to be the first to get the news.
The Deltapine Class of 16 cotton varieties are:
DP 1646 B2XF
DP 1646 B2XF is a new variety that demonstrates the ability to raise the bar on yield and fiber quality potential. Similar to DP 1050 B2RF, this variety is broadly adapted to the full-season markets of the Southeast, Mid-South and Texas. In 2015 testing, DP 1646 B2XF showed yield potential equal to, or greater than, all top check varieties. In both high-stress environments and low-stress situations, this new variety outperformed existing commercial varieties.
In head-to-head testing at 50 sites in the lower Mid-South and lower Southeast, DP 1646 B2XF averaged 100 pounds per acre more than PHY 499 WRF.
DP 1639 B2XF
This new mid-maturity variety travels well across soil types and growing regions. It demonstrated improved fiber quality performance over DP 1538 B2XF. When planted on high-production soil types with good irrigation, DP 1639 B2XF may require aggressive PGR management. It has demonstrated stable yield performance.
DP 1614 B2XF
Across 77 testing locations, DP 1614 B2XF yielded on par with DP 1522 B2XF, but delivered much better fiber quality overall, including better staple and length. It also delivered better fiber quality than popular early-maturity competitor varieties. It has a maturity similar to DP 0912 B2RF and adapts well to a wide range of soil types. It demonstrated outstanding yield potential in NPE trials.
DP 1614 B2XF averaged 1,358 pounds per acre, beating DP 1518 B2XF by an average of 150 pounds per acre in the NPE plots managed by Pace Hindsley in Marvell, AR. From the picker at harvest time, DP 1614 B2XF had a visual advantage over the other varieties, appearing bigger, fuller and showier, said Hindsley.
DP 1612 B2XF
DP 1612 B2XF demonstrated stable, high-end yield performance in NPE plots and other testing in 2015. Its best fit appears to be the High Plains of Texas, especially north of Lubbock, where it won yield tests in both irrigated and in tougher, dryland conditions. It also showed good performance in the Mid-South. This variety has a large seed size and excellent seedling vigor. It responds well to PGR management.
The Deltapine Class of 16 cotton varieties represent improvements in yield and fiber quality potential, and include Bollgard II XtendFlex cotton technology that, upon all regulatory approvals, will allow three modes of action over the top for a more flexible and reliable weed management program.
