1a.Objectives (from AD-416)
The objective of this cooperative research project is to cooperatively evaluate during the breeding process new strains of long-staple upland cottons (Acala 1517) for their ginnability and textile quality as means for guiding variety development. Desirable genes for fiber quality and other traits (e.g., insect and herbicide resistance) will be identified and used in the breeding process.
1b.Approach (from AD-416)
All projects will be conducted by evaluating the following areas:. 1)varietal interactions with mechanical processing both in the gin and the textile mill on fiber, yarn and fabric quality, and process efficiency,. 2)integrate genetic and genomic tools in the breeding process to incorporate useful genes for ginnability and textile quality, and. 3)process and evaluate in the gin and textile mill new upland cotton strains in reference to areas 1 and 2 in order to aid in cotton breeder variety selection and development.
This report documents progress for subordinate project 6235-41000-008-37S "Development of Competitive High Quality and Acala 1517 Cotton through Enhanced Ginning/Textile Processing Performance" which started July 2010 and continues research from subordinate project 6235-41000-007-11S "Enhancing Ginning Textile Processing Performance of Acala 1517 Cotton through Genomics." In FY2011, two commercial cotton cultivars (a non-transgenic conventional Acala 1517-08 and an herbicide-resistant Acala 1517-09R) were approved for release by the New Mexico Agricultural Experiment Station as part of this project. To improve upland cotton quality, it is desirable to introduce fiber traits and genes from Pima to upland cotton. To achieve this goal of improved fiber quality, extensive cross species breeding has been practiced as part of the program. In the 2010 crop year, 90 preliminary crossbred breeding lines were tested in replications in the field in Las Cruces and Artesia, NM. A number of the new breeding lines out-yielded the parent Acala 1517-99 or the standard 1517-08. These improved lines were selected based on yield potential and fiber quality, and will be further tested for their ginnability and textile quality. Other work under this project deals with developing drought- and salt-tolerant breeding lines. During crop year 2010, a number of cotton breeding lines were selected that exhibited some degree of salt and/or drought tolerance, and this work will continue during the 2011 crop year.
