Registration of 'Tamcot 73' Upland Cotton Cultivar Academic Article uri icon


  • 'Tamcot 73' upland cotton (Gossypium hirsutum L.) cultivar (Reg. No. CV-128, PI 662044) was developed by the Cotton Improvement Laboratory, Department of Soil and Crop Sciences, Texas A&M AgriLife Research. Tamcot 73 was derived from a complex of crosses that date across several decades of the upland cotton improvement program at Texas AgriLife Research. The breeding lines 93WB-57s and 95WE-48, which are closely related to TAM 0155 and TAM 2055, respectively, were crossed in 1999. The F1 and F2 generations were advanced at College Station, TX in 2000 and 2001, with an F3 plant selected in 2002. The F3:4 progeny row was bulked with subsequent generations treated as a pure line for seed increase and performance testing. Tamcot 73 is a conventional cultivar that is competitive in yield potential with the current upland cultivars available for production in central and south Texas. Tamcot 73 exhibited a high-volume-instrument upper half mean length equal to or greater than the comparison cultivars in four of five comparisons when grown under irrigated and nonirrigated culture in central and south Texas during 2005 through 2009. Uniformity of fiber length and fiber bundle strength of Tamcot 73 exceeded that of most of the commercial comparison cultivars in all environments, and micronaire was within accepted limits in all comparisons. The lint percentage of Tamcot 73 is acceptable yet below that of most current upland cultivars. Tamcot 73 provides producers with a competitive, high-quality, conventional cultivar.
