The San Joaquin Valley Cotton Board has released five new Acala and two new Pima cotton varieties. The new releases are:
OA-262, a Roundup Ready Acala from O & A Enterprises.
OA-265, the first stacked gene (BR) transgenic Acala. It is also from O & A Enterprises. It contains the first generation Bt gene (Bollgard) and is also Roundup Ready. It does not contain the Bollgard II gene, which offers control of the worm pests common to the San Joaquin Valley. Bollgard cotton is widely planted in Arizona because it is highly effective against pink bollworm, which is not a threat in the San Joaquin Valley thanks to a the grower-funded exclusion program using trapping and sterile-moth control technology. At 1,685 pounds per acre, OA-265 produced the highest yields in board tests.
OA-270, another Acala also from O & A Enterprises, is also a stacked gene Bollgard/Roundup Ready cotton similar to OA-265 and tied with it in yield scores. OA-270 has a slightly longer growing season than OA-265.
C-201, a premium fiber Acala from California Cotton Planting Seed Distributors (CPCSD), was bred to replace the current Ultima variety. C-201 produced 1,605 pounds of lint per acre. It is expected to be roller-ginned, rather than saw-ginned like most Acalas, to increase its quality. Roller-ginned Acalas have earned a price premium as high as 12-15 cents per pound over saw-ginned varieties.
C-101 is a nematode-resistant Acala from CPCSD.
OA-353, is a Pima variety from O & A Enterprises. It outyielded the S-7 standard by 157 pounds per acre.
OA-354, another Pima from O & A Enterprises produced yields of 73 pounds per acre over S-7.
O&A cottons have in the past been marketed by Delta and Pine Land Co.
The new releases bring to 40 the board-approved varieties for commercial cotton planting. This does not include so-called non-Acala, non-Pimas that also can be planted in the valley.
In other actions, the board also voted to include in its research program the testing of new transgenic cottons containing the Roundup Ready Flex gene, which will allow the use of Roundup later in the plant's growth cycle than the current Roundup Ready technology.
This technology is closely regulated by the U.S. Department of Agriculture. Until approved by USDA, all seed, gin trash and motes produced from these transgenic cottons must be destroyed.
