ACALA VARIETY TRIALS IN THE SAN JOAQUIN VALLEY

 

Acala cotton varieties were grown on about 100,000 acres out of the greatly reduced total acreage of about 275,000 acres in 2008. Part of the reason for continuing changes in acreages is overall reductions in planted cotton acreage in California in recent years, but part is also related to shifts to Pima and non-Acala Upland cotton. There are tradeoffs in shifting to Pima (typically reductions in yields) and in shifts to non-Acala Uplands (typically lower price for lint), and growers need reliable, unbiased information regarding expected lint yields and fiber quality in order to make reasonable, lower-risk decisions. The San Joaquin Valley Cotton Board will remain the avenue for varieties to enter our “Approved Variety” testing program. Within Acala testing, the combined SJV Cotton Board and the UCCE Farm Advisor Approved Acala trials represents a source for broadly-based information on varietal performance. Separate trials involving newly-available CA Upland varieties continue to be conducted by Hutmacher and staff at Shafter and West Side REC sites to complement SJVCB I Approved Acala studies. Variety evaluations for yield and quality performance for…

UCCE Approved Acala and Pima Variety Trials

 

The objectives of these studies with Acala and Pima varieties are to evaluate approved Acala varieties and Pima varieties submitted for testing under different environmental conditions and management across the San Joaquin Valley region of California. In order to provide a reasonable limit on the number of varieties in the tests, the entries include newly-approved varieties (approved by the San Joaquin Valley Cotton Board) for the current year, varieties released last year that are in their second year of testing, plus the top 4 or 5 previously-approved varieties (in terms of planted acreage). The new varieties are the focus of tests, but only remain in tests for a minimum of two years following release unless that variety moves into the top 4 or 5 varieties in planted acreage. Released varieties also may not show up in tests if companies request that the variety is for a special market and don’t want it in multiple location testing, or when seed supplies are inadequate. The Pima tests focus on approved varieties, but in the past two years have also included a non-approved hybrid that has been of interest due to yield…
