The seeds of these populations were imbibed with distilled water for about 16 hrs. and then exposed to 3.0% v/v Ethyl Methane Sulfonate (EMS) for two hrs. to produce the M1 generation. Sodium bicarbonate was used to neutralize the EMS. The M1 seeds were triple rinsed, and then hand planted. From 2002 to 2004, the two mutant populations were advanced by harvesting a single boll from each plant and bulking the seeds to generate the M2:3, M3:4, and M4:5 generations. In 2005, seed cotton was hand harvested from 3,122 individual M5 plants across both populations, saw ginned, and fiber samples evaluated using High Volume Instrument. A total of 1,582 M5 plants from TAM 94L-25 and 1,540 M5 plants from Acala 1517-99 were evaluated in 2004-2007. Individual M5 lines were selected for superior HVI fiber quality traits (long, strong, and low micronaire values. Based on the 2007 HVI analyses, 72 M5 lines of TAM 94L-25 and 54 M5 lines of Acala 1517-99 were increased in unreplicated field trials in 2008. Finally, 33 M5 lines from the TAM 94-L25 and 30 M5 lines from Acala 1517-99 mutant lines were selected for advanced evaluation at Lubbock, TX (2012, 2013, 2014, & 2015), College Station, TX (2012 & 2013) and Stoneville, MS (2012 & 2013). Fiber samples were evaluated with HVI. Data for the six M5 lines proposed for release, the respective non-mutated parental lines, and a commercial check cultivar (Fiber Max 958) were analyzed using PROC GLIMMIX, and PROC GLM. Chemical mutagenesis of TAM 94L-25 and Acala1517-99 appeared to enhance the genetic variability and generate M5 lines with improved length and/or strength in lines proposed for release. | 2096634 | PI 691517 |
