Mildew Resistant Lima Available in Delaware A lima bean resistant to downy mildew has been introduced to Delaware growers for general use, according to Dr. Vernon Fisher, professor In the Plant Science Department at the University of Delaware.

It waa after "Dover" waa released that Fisher began research on a new variety which could overcome these difficulties and still offer good resistance to downy mildew. In 1970 he began testing lines from which "Bridgeton" ultimately was developed. Bridgeton seed was of fered in 1974. The "Bridgeton" strain closely resembles “Thaxter”, which is resistant to only strain A of the downy mildew fungus. "Bridgeton” is resistant to both strains A and B and superior in uniformity of pod set. In addition, its green seed color at the processing stage of maturity makes it more desirable than “Thaxter". Fisher reports that ‘'Bridgeton” has eliminated or reduced the problems with “Dover”, such as large plant size and the associated slow harvest speed, late maturity, splitting seeds in the processing line and its pale green color. “Bridgeton” plants tend to be slightly larger than “Thaxter” and mature 1 to 3 days later. He also points out that because “Bridgeton” pods tend to separate from the plants slightly more readily than those of other cultivars, there is-an in creased need for careful handling during harvest. However, even “Bridgeton’s” resistance to strains A and B of the downy mildew fungus is not per manent, Fisher points out, but in recent years much sophisticated research has been carried out to deter mine what it takes for a new variety to succeed. If “Bridgeton” succumbs to a new strain of the downy mildew fungus, he says, researchers will be in a position to introduce a new variety quickly. Pequea Valley 4-H Meets The members of the Pequea Valley 4-H Sewing and Cooking Club met on June IS for their first project meeting. The meeting was held at Pequea Valley In termediate School. Cooking Club met at 10:30 a.m. and continued to 12:45.
