Vegetable variety testing program provides unbiased results

Variety trials demonstrate that cultivars containing the added resistance to races 4, 5 and/or 6 reduced bacterial spot infection rates and increased yields compared with varieties with only resistance to bacterial spot races 1, 2 and 3 under natural disease pressure.
Hybrid radishes have higher yields

The Florida bunch radish is one of America’s most popular garnishes and is available fresh from October through June. Growers rely on non-hybrid varieties, which offer low yield and quality.

Therefore, a variety trial was conducted during the 2009-10 fall, winter and spring seasons with 21 (hybrid and non-hybrid) varieties assessing yield and quality. Results indicate that hybrid varieties can increase radish yields and quality for Florida growers.

Snap bean yield, color rank high
Florida ranks first nationally in production, acreage and total fresh market value in snap beans. Most of the state’s snap bean crop is produced for the fresh market, with only a small percentage going to processing.

Growers rely on new varieties to increase bean yields and quality and to remain competitive in the U.S. market.

Preliminary results of a variety trial conducted during the 2010 winter with 13 varieties in two locations showed yield and color were the most important attributes for Florida bean growers. Yields followed closely behind.
