Abstract

‘FSA1602’ (Reg. no. CV-294, PI 704119) hybrid St. Augustinegrass [Stenotaphrum secundatum (Walter) Kuntze] was developed and released by the Florida Agricultural Experiment Station, University of Florida, in 2018. FSA1602 has a distinct olive blue-green color and high levels of resistance to gray leaf spot, take-all root rot, and excellent shade tolerance and turfgrass quality (TQ). It is targeted for use in residential and commercial lawns in the southern United States. FSA1602 has coarse textured leaves similar in width to ‘Floratam’ and leaf lengths similar to ‘SS-100’ (Palmetto) but shorter than Floratam. FSA1602 stolon width is larger than Floratam or Palmetto but has a mean stolon internode length shorter than either Floratam or Palmetto. It produces a dense turfgrass with high TQ that is similar to or better than Floratam and with less winter kill than Floratam, which is the most widely used St. Augustinegrass for lawns in Florida.

'FSA1602'（登记号：CV-294，PI 704119）杂交圣奥古斯丁草[Stenotaphrum secundatum (Walter) Kuntze]由佛罗里达大学佛罗里达农业试验站于2018年开发并发布。FSA1602 具有明显的橄榄蓝绿色，对灰叶斑病和全株根腐病具有较高的抗性，耐阴性和草坪草质量（TQ）极佳。它主要用于美国南部的住宅和商业草坪。FSA1602 的叶片纹理较粗，宽度与'Floratam'相似，叶片长度与'SS-100'（棕榈）相似，但比 Floratam 短。FSA1602 的匍匐茎宽度大于 "Floratam "或 "Palmetto"，但平均匍匐茎节间长度比 "Floratam "或 "Palmetto "短。FSA1602 生产的草坪密度高、TQ 高，与 Floratam 相似或更胜一筹，但冬季死亡的数量比 Floratam 少，而 Floratam 是佛罗里达州草坪中使用最广泛的圣奥古斯丁草。

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.
