Abstract
Several promising new asparagus hybrids have been evaluated in field trials at the University of California, Riverside Agricultural Experiment Station.
Over the past six years, data on yield, spear number and quality have been collected on a replicated trial established in 1990. The entries include 7 promising clonal hybrid UCR breeding lines, S870 (an open-pollinated line from the UCR breeding program), UC157, Ida Lea, Apollo, Atlas, Jersey Giant, and Greenwich.
Similar trials were planted at UCR, in the Coachella Valley, and at two Delta locations.
The most promising new line is F189 x HS104 which over six years had a total marketable yield 45% higher than that of UC157. This line also had the highest early yield.
Average spear size of F189 x HS104 was somewhat larger (29.1 grams) than UC157 (22.4 grams). Atlas was the second highest yielding line overall and had the largest spear size (32.6 grams), but tended to be slightly later than UC157. Ida Lea was also higher yielding than UC157 in most years.
Early results of a replicated trial planted in 1994 are described.
This trial included 31 lines: the 6 most promising hybrid UCR breeding lines from the 1990 trial as well as 18 lines which performed well in the unreplicated portion of the 1990 trial.
