Deltapine Announces Class of 16 Varieties
Improved fiber quality, stable high-yield performance and a better weed control system are among the solutions being brought to market with four new Deltapine Class of 16 cotton varieties.
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.
“What we’re most proud about with the Class of 16 is that it brings to the market not only varieties with improved yield potential over existing commercial lines, but also excellent fiber quality over and above many existing commercial lines today,” said Keylon Gholston, Deltapine product manager. “These four Bollgard II XtendFlex cotton varieties raise the bar on yield and fiber quality potential across early-maturity, mid-maturity and mid- to full-maturity markets. And of course, they all include the Bollgard II XtendFlex cotton technology that allows growers to be more effective and flexible with their weed control.”
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.
“It was by far the best cotton in our NPE trial, averaging 1,518 pounds per acre,” said Rodney Dawson in Hawkinsville, GA. “It’s one of the showier cottons, and it looked good. I had a guy flying over the field, and he said all season long that this variety was going to win the trials. It had an average loan of 51.47 cents. Micronaire was 4.6. The staple was 38. The strength was 29.40. Uniformity was 80.5. The grades and yield really stood out.”
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.
“I like the way it came up and the way it grew off,” said Jack Huerkamp in Macon, MS. “But what I really liked about it was its yield. It averaged 1,721 pounds per acre. It was no less than 250 pounds better than the closest check in the NPE trial, and that included DP 1321 B2RF. It also graded well. I like this variety.”
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.
“I was not expecting this variety to beat DP 1518 B2XF, but it did,” Hindsley said. “DP 1614 B2XF has huge potential. I am always amazed at how breeders can increase yield potential in cotton. Well, they have certainly raised the bar with DP 1614 B2XF. I am as excited about cotton production as I have ever been.”
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.
“I found it very similar to DP 1212 B2RF, which is a variety we have liked for three years,” said Greg Martin in Brownfield, Texas. “It yielded 2,052 pounds per acre under pivot irrigation at an altitude of 3,700 feet – that’s pretty good. The cotton went into the loan at 56.6 cents. It delivered outstanding fiber quality, with good staple and length. Quality is no less important than yield out here, and this variety grades very well.”
DP 1612 B2XF is like DP 1212 B2RF with better weed control, said Martin.
“I was hoping this variety candidate would advance,” he said. “In addition to good yield (potential) and fiber quality, it has Bollgard II XtendFlex (cotton technology), which we need for more efficient weed control. Once approved, the use of dicamba will be another tool to help control resistant weeds.”
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.
“We are very proud to bring the Deltapine Class of 16 to market, raising the standard for yield and quality potential in growing regions across the Belt,” said Gholston. “The hard work and dedication of the almost 200 Deltapine NPE farmers once again helps drive production advancements, moving our industry forward with the goal of making it more efficient and profitable to grow cotton.”
