Variety trials with cos or romaine-type lettuce indicate that quicker-maturing varieties will soon be available to San Diego County growers. The breeding line 60,375 was found to mature well ahead of the standard variety, Parris Island. Total yields were similar, and the new variety also has attractive dark-green leaves of good quality and size for an attractive pack.
