The cotton variety FM 2202GL is disclosed. The invention relates to seeds, plants, plant cells, plant tissue, harvested products and cotton lint as well as to hybrid cotton plants and seeds obtained by repeatedly crossing plants of variety FM 2202GL with other plants. The invention also relates to plants and varieties produced by the method of essential derivation from plants of FM 2202GL and to plants of FM 2202GL reproduced by vegetative methods, including but not limited to tissue culture of regenerable cells or tissue from FM 2202GL.

The present invention provides use of a photoperiod-sensitive genic male sterility mutant of cotton in crossbreeding or hybrid seed production. The fertility of the photoperiod-sensitive genic male sterility mutant of cotton is influenced by the photoperiod. The photoperiod characteristic of the photoperiod-sensitive genic male sterility mutant of cotton is that, the photoperiod-sensitive genic male sterility mutant of cotton shows normal fertility when the illumination time is shorter than 11.5 h and shows genic male sterility when the illumination time is longer than 12 h; the photoperiod-sensitive genic male sterility mutant of cotton is in a fertility change period when the illumination time is in a range of 11.5-12 h and has less pollen. The photoperiod-sensitive genic male sterility mutant of cotton is PSM1, and/or a photoperiod-sensitive genic sterile line obtained through selective breeding of hybridized and/or backcrossed and/or self-bred offsprings of the PSM1.

An identified 90 bp sequence insertion in the GB0331 genome disrupts the coding sequence of the FAD2-1D gene near the 3′ end of the protein coding region. This sequence is not found in reference genomes of other Gossypium species. This DNA segment can be used to track the high oleic fad-2-1D mutant allele for introgression into cotton varieties such as Pima and upland cotton varieties. This enables a non-GMO strategy to elevate the oleic acid content of commercial cottonseed oil.

The invention relates to the novel cotton variety designated 19R325B3TXF. Provided by the invention are the seeds, plants, plant parts and derivatives of the cotton variety 19R325B3TXF. Also provided by the invention are methods of using cotton variety 19R325B3TXF and products derived therefrom. Still further provided by the invention are methods for producing cotton plants by crossing the cotton variety 19R325B3TXF with itself or another cotton variety and plants and seeds produced by such methods.
