摘要
“Tamcot 421”（修订）否。CV-149, PI 706649)是由土壤与作物科学系棉花改良实验室开发的海岛(Gossypium barbadense L.)/陆地（G. hirsutum L.）品种，并于2017年由德州农牧农业生物研究所发布。这个种间自交系是一个复杂的早期高地杂交品种和一个海岛育种品种（‘Gaddis’/‘Puerto ric556’）杂交的结果。通过大量仪器测量，Tamcot 421表现出与商品品种相当的纤维性状。在不同年份和地点的多次重复试验中，皮棉产量稳定，通常与商品品种没有差异或高于商品品种。植物形态和结果习性是典型的陆地棉。该品种的开发和上市，是一个具有高产量潜力和优良纤维品质的品种，是一个海岛亲本和旱地亲本各占50%血统的品种。
‘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.
