Abstract
Arkot 1102ne (Reg. no. GP-1142; PI 702558) is a conventional, nectariless cotton (Gossypium hirsutum L.) germplasm line released by the Arkansas Agricultural Experiment Station in October 2022. The germplasm line represents an ongoing effort to develop improved genotypes with enhanced yield, yield components, seed traits, earliness, host plant resistance, and fiber properties. Arkot 1102ne was compared to ‘UA48’ and ‘UA222’ over 5 years and four test sites in Arkansas. Across all the test sites, lint yields of Arkot 1102ne were 7.9% and 20.8% higher than those of UA222 and UA48, respectively, due to its higher lint percentage, seed per area, and fiber density. Arkot 1102ne produced the highest average yield of 21 genotypes over 10 locations in the 2019 Regional Breeders’ Network Test (RBTN). Arkot 1102ne produced the highest oil and protein percentages at four 2019 RBTN locations where seed were evaluated. Host plant resistance traits that have been measured on Arkot 1102ne include bacterial blight resistance and Verticillium wilt tolerance. Leaf pubescence and bract trichome density of Arkot 1102ne were intermediate between UA48 and UA222, but stem pubescence was lower. This combination of host plant resistance and yield components should lead to more stable yield production over contrasting environments. The fiber quality of Arkot 1102ne was lower than UA48 and was similar to that of UA222.
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.
