Phytogen Seed Co. LLC has introduced two new Roundup Ready® varieties that exhibit high yield potential in the San Joaquin Valley, CA. PHY 710 R Acala is a Roundup Ready® conversion of PHY 78 Acala, while PHY 810 R Pima is a Roundup Ready® conversion of PSC 57 Pima. PHY 710 R Acala and PHY 810 R Pima were developed by the Phytogen Seed Co. breeding program at Corcoran, CA. The key objectives were to develop Roundup Ready® varieties which would capture the full-season potential of the San Joaquin Valley coupled with consistent high yield potential and fiber quality. Field testing was conducted over two years (2003 – 2004) by Phytogen Seed Company, Corcoran, CA. PHY 710 R Acala yielded significantly more than Acala Maxxa and was comparable to the recurrent parent, PHY 78 Acala, indicating it to be a faithful conversion of the recurrent parent. PHY 710 R Acala has fiber quality equal to PHY 78 Acala and is improved in both uniformity and elongation as compared to Acala Maxxa, the San Joaquin Valley Cotton Board (SJVCB) Acala variety standard. PHY 810 R Pima yields were significantly higher than Pima S-7 and the recurrent parent PSC 57 Pima (a yield advantage of 7.9%). PHY 810 R Pima will have a fit in specific growing areas and soil types in the San Joaquin Valley, CA where PSC 57 Pima has been a consistent yielder, and in those locations where growers desire a Pima variety with tolerance to glyphosate. PHY 810 R Pima has very good fiber qualities comparable to the recurrent parent PSC 57 Pima and Pima S-7, with significant improvements in fiber strength T1 compared to Pima S-7, the San Joaquin Valley Cotton Board (SJVCB) Pima variety standard.
