Abstract

‘CP 13-1954’ (Reg. no. CV-218, PI 704104) sugarcane (Saccharum spp. hybrid) was developed through cooperative research conducted by the USDA–ARS, the University of Florida, and the Florida Sugar Cane League, Inc., and released to growers for organic (muck) soils in Florida in June 2020. The parentage of CP 13-1954 is ‘CP 85-1491’ × Poly 09-24. Based on the results of three crops (plant cane, first ratoon, and second ratoon) in field trials conducted at five locations, CP 13-1954 had higher cane yield (16.2%), sucrose yield (15.6%), and economic index (29.7%) at P < .05 compared with the reference cultivar, ‘CP 96-1252’. CP 13-1954 stalks are usually taller than the reference cultivar, ‘CP 00-1101’, with small-to-medium diameter, and exhibits resistance to ratoon stunting disease, Sugarcane mosaic virus strain E, brown rust, orange rust, and smut and moderate resistance to leaf scald on muck soils in Florida. CP 13-1954 has Bru1 locus that provides resistance against brown rust. CP 13-1954 showed moderate cold tolerance among all the tested cultivars.

为佛罗里达有机土壤注册 "CP 13-1954 "甘蔗

CP 13-1954"（登记号：CV-218，PI 704104）甘蔗（蔗属杂交种）是由美国农业部-农业科学研究院、佛罗里达大学和佛罗里达甘蔗联盟公司通过合作研究开发的，并于 2020 年 6 月在佛罗里达州的有机（泥土）土壤上向种植者发布。CP 13-1954 的亲本是'CP 85-1491' × Poly 09-24。在五个地点进行的田间试验中，根据三茬作物（植蔗、第一茬和第二茬）的结果，CP 13-1954 在 P < .05 时的甘蔗产量（16.2%）、蔗糖产量（15.6%）和经济指标（29.7%）均高于参比品种'CP 96-1252'。CP 13-1954 的茎秆通常比参试品种'CP 00-1101'高，直径从小径到中径，在佛罗里达州的淤泥土壤上表现出对轮纹病、甘蔗花叶病毒 E 株、褐锈病、橙锈病和烟粉虱的抗性以及对叶片烫伤的中等抗性。CP 13-1954 具有 Bru1 基因座，可抗棕色锈病。CP 13-1954 在所有测试品种中表现出中等的耐寒性。

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.
