Research Report 75-2 September 17, 1974

Carrot Variety Trials ,t ......
R. B. Forbes '
Associate Soils Chemist

Replicated Trials F 24 1976

At the Sanford Center on Leon fine sand, 27 varietieslor lines of fr sh
market carrots were planted in 3 row plots along with13. Al1 sfF,&$p sor
type carrots. All varieties were replicated 5 times in randomized blocks.

At the Center's Zellwood farm (Everglades mucky peat) some 35 lines of
fresh market carrots and 13 lines of processor carrots were planted, also in
5 replicates.

Growing conditions were normal at both locations. Blight was present
during the later part of the season, necessitating a minimal fungicide spray
program to maintain plots until harvest. The observational and breeding lines
were grown with no fungicides through the whole season to provide a more
rigorous blight trial.

Observational Plantings

Some 35 selections and new hybrids were planted in single row plots, at
both locations, for observation of various plant characters, including disease
resistance.

Carrot Breeding Lines Cooperative USDA Program

Several hundred advanced breeding lines and planting stocks for observation
of disease resistance and other characters were grown in Zellwood in a cooperative
study with Dr. J. 0. Strandberg, Associate Plant Pathologist of this Center,
Dr. M. J. Bassett of the Vegetable Crops Department at the main Station in
Gainesville and Dr. C. E. Petersen, USDA, Madison, Wisconsin.

Additional plots were planted and maintained in a disease screening trial
for Dr. L. R. Baker of MSU and a post-harvest disease study in cooperation
with Dr. Ralph Segall of the USDA group in Orlando.
