| Abstract:
Asparagus cultivars were rated for yield performance and susceptibility to Fusarium crown and root rot in two locations in Connecticut. In Windsor, CT, the cultivars: Jersey Supreme, Jersey Giant, Jersey Titan, Jersey Knight, Mary Washington, Centennial, Rutgers Syn #2, Emerald, and experimental line D2 X 22–8 were planted on a fine loamy sand soil in 1983. Spears were cut, trimmed to 22.5 cm, counted and weighed in the springs of 1987–1992. Over the six years, the cumulative yield was greatest for Jersey Supreme, Jersey Giant, Emerald and Rutgers Syn#2. The highest percentage of surviving crowns after 5 years was found for Emerald and Rutgers Syn#2 and the lowest for cultivar D2 X 22–8 and Centennial. The cultivar Emerald produced spears with a distinguishable light green color. In Hamden, CT, the cultivars Mary Washington, Jacq. Ma. 2011, Jacq. Ma. 2014, Lucullus 327, Greenwich, Jersey Prince, Jersey General, Jersey Giant, and Jersey King were planted on a sandy loam in 1990 and harvested in 1992–1997. The cumulative yield for the six years was greatest for Jacq. Ma. 2014, Lucullus 327, and Jersey Giant. The cultivar Jacq. Ma. 2014 produced very large spears and emerged earlier than the other cultivars. Yields were lowest for Jacq. Ma. 2011, Mary Washington and Jersey Prince which had poor vigor and chlorotic foliage. The cultivars, Jersey Supreme, Jersey Giant, and Jacq. Ma. 2014 appear to be the most vigorous and promising cultivars for Connecticut. | |
