“…TAM 94L‐25‐M24, TAM 94L‐25‐M25, and TAM 94L‐25‐M30 were selected from a population developed by treating the germplasm line TAM 94L‐25 (Smith, 2003) with EMS. TAM 94L‐25 was released in 2003 by Texas AgriLife Research and derived from the cross of TAM 87 G 3 ‐27 (PI 578054; Smith and Niles, 1994) with an unreleased breeding line developed by G.A. Niles.…”

Three putative mutant upland cotton (Gossypium hirsutum L.) germplasm lines, TAM 94L‐25‐M24, (Reg. No. GP‐952, PI 664553), TAM 94L‐25‐M25 (Reg. No. GP‐953, PI 664554), and TAM 94L‐25‐M30 (Reg. No. GP‐954, PI 664555), were developed by the Cotton Improvement Laboratory, Department of Soil and Crop Sciences, Texas AgriLife Research and released in 2010. These lines were developed by treating the parent germplasm line, TAM 94L‐25 (PI 631440), an upland cotton line with improved high‐volume instrument (HVI) upper‐half mean length (UHML), with the chemical mutagen ethyl methanesulfonate. TAM 94L‐25‐M24, TAM 94L‐25‐M25, and TAM 94L‐25‐M30 exhibited UHML and fiber bundle tenacity that exceeded that of the parent, TAM 94L‐25. These three lines yielded as much or more than the M0 parent and exhibited other HVI fiber‐quality parameters that were within acceptable ranges. TAM 94L‐25‐M24, TAM 94L‐25‐M25, and TAM 94L‐25‐M30 should be useful in creating cultivars with improved fiber length and strength.

“…The majority of the efforts to attain these improved fiber traits has been through hybridization of G. hirsutum and G. barbadense , with little, if any, success since the first efforts were reported in the 1860s (Smith et al, 1999). Near‐long staple germplasm lines and cultivars have been developed within upland, including TAM 94L‐25 (Smith, 2003a), TTU 202‐1107‐B (PI 613162) and TTU 271‐2155‐C (PI 613163) mutant germplasm lines (Auld et al, 2000), TAM 87D 3 ‐24 (PI 578053) (Smith and Niles, 1994), ‘Fibermax 832’ (PI 603955), and Deltapine 491. However, the germplasm lines identified herein may be the first ELS uplands developed and released in the United States from intraspecific hybridization and selection.…”

Eight extra‐long staple (ELS) upland cotton (Gossypium hirsutum L.) germplasm lines, TAM A106‐15 ELS (Reg. No. GP‐894, PI 654359), TAM A106‐16 ELS (Reg. No. GP‐895, PI 654360), TAM B147‐21 ELS (Reg. No. GP‐896, PI 654361), TAM B182‐33 ELS (Reg. No. GP‐897, PI 654362), TAM C66‐16 ELS (Reg. No. GP‐898, PI 654363), TAM C66‐26 ELS (Reg. No. GP‐899, PI 654364), TAM C147‐42 ELS (Reg. No. GP‐900, PI 654365), and TAM C155‐22 ELS (Reg. No. GP‐901, PI 654366), were developed by the Cotton Improvement Laboratory, Department of Soil and Crop Sciences, Texas AgriLife Research (Texas A&M University, College Station), and released in 2008 as part of an ongoing effort to create germplasm with combinations of improved fiber quality parameters, especially upper half mean (UHM) length and fiber bundle strength. All ELS lines exhibited high volume instrument (HVI) UHM fiber length greater than 32.0 mm, which is the minimum UHM to be classified as ELS upland according to Cotton Incorporated. Seven of the eight lines equaled or exceeded the minimum UHM length of 34.8 mm for pima (G. barbadense L.) in the USDA 2007 pima loan schedule in at least one performance trial. Fiber bundle strengths of the eight lines were equal to or higher than ‘Fibermax 832’.

“…An early fruiting upland cotton line that has superior fiber length and strength even under dryland conditions. It is a cross between two breeding lines, TAM 870 3 –37 and TAM 87G 3 –27 (Smith, 1994). TAM 870 3 –37 has a complex pedigree that includes Stoneville 1023, ‘Lankart 57’, Rogers Acala, Lankart 3840, ‘Gregg’, ‘Fox 4’, and Acala 5675 (Smith, 2003).…”

Advanced Fiber Information System (AFIS) mean fiber length by weight (Lw), fiber length development period (FLDP), and average daily fiber length growth rates (ADGR) were determined for four experimental strains and three cultivars of upland cotton, Gossypium hirsutum L., in 1998 and 1999 in College Station, TX. TAM 94L‐25 and TAM 94M‐14, near‐long staple sib lines developed by the Texas Agricultural Experiment Station (TAES), were compared with five upland cotton genotypes that varied in high‐volume instrument (HVI) upper half mean (UHM) fiber length. The FLDP was determined as the number of days postanthesis (DPA) until fibers reached a Lw greater than or equal to their Lw at boll opening. Final average daily growth rate (FADGR) was calculated as the average Lw d−1 from anthesis to open boll. Length by weight was determined at 3‐d intervals from 16 DPA until boll opening. With a higher FADGR and longer FLDP, TAM 94L‐25 and TAM 94M‐14 exhibited the longest final Lw TAM 94L‐25 had a higher FADGR than the commercial cultivars Suregrow 125 and Tamcot CAMD‐E, while TAES strain 94WD‐17 exhibited the lowest FADGR. The broad‐sense heritability estimate for final Lw across years was 0.88.
