Abstract

‘Coastcross II’ (CC II; Reg. no. CV-49, PI 673409) forage bermudagrass (Cynodon sp.) was released as an associate cultivar in Georgia in July 2014. Coastcross II originated from gamma-ray irradiation of sprigs of Coastcross I (CC I) in 1971. After irradiation, greater than a half million sprigs were planted in north Georgia (Blairsville), where CC II was one of four surviving plants after winter freezes. Subsequent testing has shown that CC II has superior yields to CC I and is comparable to ‘Tifton 85’. Coastcross II also has significantly higher tolerance to bermudagrass stem maggot than fine-stemmed cultivars. Coastcross II has significantly finer stems than Tifton 85, which makes it more conducive to hay production.

Coastcross II "牧草注册

Coastcross II"（CC II；登记号：CV-49，PI 673409）牧草百慕大草（Cynodon sp.）于 2014 年 7 月在佐治亚州作为副栽培品种发布。海岸杂交 II 起源于 1971 年对海岸杂交 I（CC I）的嫩枝进行伽马射线辐照。辐照后，超过 50 万株树枝被种植在佐治亚州北部（布莱尔斯维尔），CC II 是经过冬季冰冻后存活的四株植物之一。随后的测试表明，CC II 的产量优于 CC I，与 "Tifton 85 "不相上下。海岸杂交 II 对百慕大草茎蛆的耐受性也明显高于细茎栽培品种。海岸十字 II 的茎明显比 Tifton 85 细，这使其更有利于干草生产。

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.
