ASPARAGUS VARIETY ASSESSMENT AND CULTIVAR DEVELOPMENT AT THE UNIVERSITY OF GUELPH |
| Authors: | D.J. Wolyn, J. Jamieson |
| Abstract:
The asparagus breeding program at the University of Guelph is currently: developing new varieties adapted to Canadian conditions, evaluating hybrids from other breeding programs, and assessing the potential for clonally propagated varieties. Certain Lucullus lines and hybrids from the Rutgers' breeding program performed better than the standard variety Viking in an observation trial. Superior females for breeding have been identifiedin test-crosses to males from the Rutgers program. New supermales were identified and crossed to superior females; these hybrids will be first harvested in 1989. Only one of 12 clonally propagated genotypes yielded better than Viking but not greater than what is usually observed for superior all-male seed propagated hybrids. | |
