Identification and development of cotton germplasm and potential breeding lines with improved Fusarium wilt (FOV) resistance, fiber quality, and yield


OBJECTIVES (related to #(1) and #(2) above:
1. Develop cotton progeny and breeding populations segregating for FOV race 4 resistance. (approximately 2/3 of efforts will focus on Upland / Acala types of cotton, with remainder of effort on Pima germplasm).

For 2013 evaluations: Over 500 entries were sent from Mauricio Ulloa in Lubbock, TX representing populations derived from cooperative work with Bob Hutmacher and Steve Wright of UCCE in recent years. These entries were planted at one major field screening site for race 4 FOV in Tulare County, and evaluations of all entries were done in the summer and fall of 2013. For 2014 evaluations: Over 410 entries were sent from Mauricio Ulloa of USDA-ARS in Lubbock, TX representing populations of interest. All of the entries were planted at the Tulare County FOV screening site in May, 2014 and about half of the entries were also planted at the Kern County FOV screening site that we have developed

2014 Verticillium Wilt resistance of cotton germplasm


Objectives of Research:
The overall objective of this research was to identify and utilize field screening locations with a moderate to high level of sustained Verticillium wilt inoculum to provide a location for field screening of cotton germplasm of interest in CA Cotton production. The aim of the work is to utilize locations with a Verticillium wilt population for field screenings to identify relative susceptibility of newer commercial varieties of interest for CA Cotton production, and to then screen experimentals from both commercial breeders or seed companies plus those from USDA-ARS or other public breeding programs…

2014 Summary Deficit Irrigation and Alternative Pima and Acala Cotton Management


2013 was the second year and 2014 is the third year of a field research trial that focuses on deficit drip management practices that could be utilized to tighten up and shorten the fruit production period and evaluation of these practices using both full-season commercial Acala and Pima cultivars and experimental germplasm (USDA-ARS and/or commercial companies)…

2014 Field Evaluation Support and Variety Screening Evaluations


This project matches the efforts in a similar named project supported by the California Cotton Incorporated State Support Committee. The difference between the two is that the Cotton Incorporated part of the project is set up to support only Acala and Upland cultivar research, while the CA Cotton Alliance project supplements that support and also allows us to also focus on Pima variety screening and related efforts for Pima production. CA Cotton Alliance funds support the same areas of work as the Cotton Incorporated funded project, but since Cotton Incorporated funds are collected for Upland variety work, the expanded efforts in screening, including Pima, are covered under this same project summary report…
