Deltapine Rolls Out Five New Varieties in Class of ’21
December 14, 2020 Two new Bollgard 3 XtendFlex cotton varieties with resistance to both reniform and root-knot nematodes highlight the five new varieties making up the Deltapine Class of ’21.
The varieties were announced during the 2020 Deltapine New Product Evaluator (NPE) Summit, held virtually for the first time.
“The Class of ’20 varieties set the bar so high that I expected it to be tough to advance many candidates out of NPE for the Class of ’21,” said Keylon Gholston, Deltapine cotton products manager. “However, two varieties that advanced for the Class of ’21 – DP 2115 B3XF and DP 2127 B3XF – stood out from a performance perspective, showing potential to yield above DP 1646 B2XF and the Class of ’20 varieties.”
Two nematode-resistant Bollgard 3 XtendFlex cotton varieties showing resistance to both reniform and root-knot nematodes – one for the southern U.S. and one for the Mid-South and Texas – were also named to the Deltapine Class of ’21.
“These two new varieties — DP 2141NR B3XF and DP 2143NR B3XF — give us Belt-wide coverage for growers who have fields with reniform or root-knot nematode pressure,” Gholston said. “Both of these varieties demonstrated very competitive yield potential on non-nematode fields, but especially shined under nematode pressure.”
The Deltapine Class of ’21 cotton varieties are:
- DP 2115 B3XF is an early-maturity Bollgard 3 XtendFlex variety that showed outstanding yield potential in NPE plots and demonstrated good storm tolerance.
- DP 2123 B3XF is an early- to mid-maturity Bollgard 3 XtendFlex variety that demonstrated the ability to perform under heat and drought stress and strong seedling vigor.
- DP 2127 B3XF is an early- to mid-maturity Bollgard 3 XtendFlex variety that showed solid performance in NPE plots across the Belt with high yield potential.
- DP 2141NR B3XF is a mid- to full-maturity Bollgard 3 XtendFlex variety showing resistance to both reniform and root-knot nematodes with outstanding yield potential.
- DP 2143NR B3XF is a mid- to full-maturity Bollgard 3 XtendFlex variety showing resistance to reniform and root-knot nematodes and moderate tolerance to Verticillium
On-Farm Performance
In Baker, FL, NPE growers James and Nick Marshall farm fields with heavy nematode pressure, and DP 2141NR B3XF showed promising performance.
“This variety had an outstanding outlook in September, with 50 to 60 fruiting positions set before it was hit by two hurricanes at harvest time,” said Nick. “The field has a history of both reniform and root-knot nematode pressure, and other varieties have not done well there. This variety grew off well and stayed healthy all season long. It definitely worked, and we were pleased with it. I feel like it will be a good choice on ground with nematode pressure or even in fields with no pressure.”
NPE growers Daryl and Doyle Schniers near San Angelo, TX, gave a thumbs-up for advancement of DP 2143NR B3XF after their experience with the variety.
“We planted it in a three-repetition check trial in a drip-irrigation field with heavy pressure, comparing it against another nematode-resistant variety and a variety that is not resistant,” said Daryl. “DP 2143NR B3XF outyielded the nonresistant variety by 2½ bales (per acre) and edged out the nematode-resistant variety. It grew right through the early-season nematode pressure, and we practically saw no damage in the variety. We like the fact that it is a Bollgard 3 XtendFlex variety. I think it is going to work for us.”
For the Tough Acre
With DP 2123 B3XF, Deltapine brings another DryTough cotton variety into the West Texas market. This variety for the Northern High Plains has a larger seed size, demonstrated excellent seedling vigor and stand establishment potential, and showed very competitive yield potential under light water and moderate water irrigation capacities.
The five new Deltapine Class of ’21 varieties were evaluated by NPE growers located in all regions of the Cotton Belt. The results of the growers’ large-acre variety plots and their feedback on management and performance were instrumental in determining the Class of ’21.
“This class of cotton varieties continues the Deltapine tradition of developing new products and taking them to market after having been proven by growers,” said Gholston. “We thank the many NPE growers whose hard work and dedication to this program helps bring new cotton varieties to the market for all U.S. producers.”
