COMPARISON OF SEED QUALITY OF OREGON VERSUS TEXAS PRODUCED ANNUAL RYEGRASS
Almost all annual ryegrass seed planted in the southern USA is produced in Oregon; however, some annual ryegrass seed is produced in Texas annually. This study was conducted to provide information on the quality of Oregon versus Texas produced seed.
Seed from six genotypes of annual ryegrass were grown and produced seed in both Oregon and Texas. This seed was tested for seed weight, % germination and for seedling vigor. Results indicated that Oregon produced seed had a higher 1000 seed weight, higher percent germination, and a slightly higher dry matter production from plants grown in the greenhouse for 50 d. Differences between genotypes for all of the above characters were observed and are discussed in this paper. This study confirmed the hypothesis that Oregon produced seed has higher quality and should continued to be planted in Texas.
