Narrative
Leafy and annual Italian ryegrass forage cv. capable of producing early yields superior to Marshall varieties of annual ryegrass. Single hay clipping studies in Southern Oklahoma generated yields comparable to Marshall annual ryegrass. In Oklahoma, fall and spring forage performance trials have indicated superior spring yields and competitive fall yields when compared to Marshall (annual) and Linn (perennial). Distinctive feature relates to extremely early maturity and early forage production potential. When fall sown in Oct., heading usually occurs in March to April. Two weeks earlier in flowering when compared to Marshall and Ribeye and two weeks earlier than Linn. Medium resistance to Crown rust (Puccinia coronata) and appears tolerant of most other common diseases of ryegrass known to occur in the Southern Plains. The extremely early heading date makes this variety useful for growers interested in a cool-season grass forage which is rapid in growth, nutritious and palatable to livestock and can be utilized for livestock grazing or haying, then quickly removed for the sowing of no-till summer crops. Recommended for areas in the U.S. where the mean temperature is above 16 C in October. Also suggested for use in blends with later maturity annual ryegrass varieties to enhance the early forage production potential of the germplasm. For more inforamtion click here

Pedigree
Description:
A diploid form which carries several B-chromosomes. As a consequence, the chromosome number exceeds 2n=2x=14 and is not stable. However, the genetic stability is not compromised by the presence of supernumerary chromosomes. Originally developed in Japan and evaluated for release in the U.S. by the Yamaguchi Agric. Exp. Station, Oouchi-Mihori, Yamaguchi, Japan, and the USDA-ARS, Grazinglands Res. Sta., El Reno, OK. Developed by utilizing the annual ryegrass population Yamaiku No. 78 which is a sub-selection of Minamiwase. Selected from Yamaiku No. 78 by selecting 72 vigorous individuals and bulking the seed.
