Indianapolis, Indiana (June 8, 2007)--2006 was a banner year for PhytoGen™ brand cottonseed varieties based on field trial performance. In university official variety trials (OVTs) across the southern U.S. Cotton Belt, several new cotton varieties from PhytoGen Cottonseed provided unsurpassed yield results.
The outstanding performance of PhytoGen™ brand cottonseed varieties reflects the research and development investment and quality of PhytoGen Cottonseed’s breeding program. Among the PhytoGen brand cottonseed varieties tested in 2006 university OVTs were the 400 series, such as PHY 480 WR and PHY 485 WRF, which were developed using high yielding and broadly adapted PSC 355 as their key parent lineage. Also tested were early maturity varieties that were created using new proprietary germplasm — PHY 370 WR and PHY 310 R.
Yield results averaged across multiple state OVTs in 2005 and 2006 showed PhytoGen brand cottonseed varieties to be “top of the class” when compared to other industry variety standards that were in the same replicated trials.
In 561 replicated OVTs across the Cotton Belt, PHY 370 WR netted an average 1,295-pound-per-acre lint yield. Comparable variety standards in the trial showed average yields of 1,276, 1,271, 1,266, 1,253 and 1,121 for ST 4575BR, DP 445 BG/RR, ST 5242BR, DP 444 BG/RR and FM 960B2R, respectively.
Comparison for varieties with Roundup Ready Flex technology included reviewing results from 392 replicated OVTs. PHY 485 WRF had an average lint yield of 1,202 compared with 1,173 for DP 117 B2RF, 1,167 for ST 4554B2RF, 1,138 for ST 4357B2RF and 1,137 for DP 143 B2RF.

Positive feedback from growers throughout the Cotton Belt validates the positive results reported from the university OVT trials. “370 (PHY 370 WR) averaged 1,562 pounds on 250 acres in 2006,” said Boyce Miller of Transylvania, La. “It had a 1-pound yield advantage over 555 (DP 555 BG/RR) and because of the staple length netted an extra $6 per bale profit. Based of this performance, 370 will be planted on half of our 1,300 acres in 2007 because it consistently produces a good yield and grades well.”
Boyer Britt of Indianola, Miss., was also impressed. “When I compare 485 (PHY 485 WRF) with other varieties I grow, I was shocked by the amount of fruit the plants held throughout the season. We saw about a 1,320 pound per acre yield in 2006 and initial gin results show a premium of 4.5 cents on a government loan. It’s one of the best cotton varieties I’ve ever picked.”
Through its affiliation with Dow AgroSciences, PhytoGen Cottonseed is committed to continuously providing cotton growers premier choices in transgenic cotton varieties. PhytoGen Cottonseed’s legacy of elite germplasm, high yields, maximum quality and innovative technology provide the foundation needed to be a leading choice in the cotton industry.
PhytoGen Cottonseed was formed in 1998 from a joint venture between the J.G. Boswell Company (a world-class cotton producer based in California), and Mycogen Seeds (an affiliate of Dow AgroSciences). In addition to high quality breeding capabilities, PhytoGen Cottonseed gained access to the vast research efforts that Dow AgroSciences puts into insect-, disease- and herbicide-tolerant technologies.
This access has led to the addition of PhytoGen brand cottonseed varieties with WideStrike™ Insect Protection, a two-gene insect protection trait from Dow AgroSciences for season-long protection against a broad spectrum of worm pests. PhytoGen Cottonseed has also added the latest in herbicide-tolerance technology to their lineup, including Roundup Ready® Flex.
