Abstract
‘Tamcot 421’ (Reg. no. CV-149, PI 706649) is a Sea Island (Gossypium barbadense L.)/upland (G. hirsutum L.) cultivar developed by the Cotton Improvement Laboratory, Department of Soil and Crop Sciences and released in 2017 by Texas A&M AgriLife Research. This interspecific inbred line was the result of hybridization of a complex early generation upland hybrid and a Sea Island breeding line (‘Gaddis’/‘Puerto Rican 556’). Tamcot 421 demonstrated fiber traits that were comparable to commercial cultivars as measured by high volume instrumentation. Lint yields were stable and generally either not different or higher than commercial cultivars in multiple replicated trials across years and locations. Plant morphology and fruiting habit were typical of upland cotton. Development and release of this cultivar represents an unusual combination of high-yield potential and good fiber quality in a line with a 50/50 pedigree contribution of Sea Island and upland parents.
期刊介绍：
The Journal of Plant Registrations is an official publication of the Crop Science Society of America and the premier international venue for plant breeders, geneticists, and genome biologists to publish research describing new and novel plant cultivars, germplasms, parental lines, genetic stocks, and genomic mapping populations. In addition to biomedical, nutritional, and agricultural scientists, the intended audience includes policy makers, humanitarian organizations, and all facets of food, feed, fiber, bioenergy, and shelter industries. The scope of articles includes (1) cultivar, germplasm, parental line, genetic stock, and mapping population registration manuscripts, (2) short manuscripts characterizing accessions held within Plant Germplasm Collection Systems, and (3) descriptions of plant genetic materials that have made a major impact on agricultural security. Registration of plant genetic resources, item (1) above, requires deposit of plant genetic material into the USDA ARS National Plant Germplasm System prior to publication.
