SECOND INTERNATIONAL ASPARAGUS CULTIVAR TRIAL FINAL REPORT |
| Author: | B.L. Benson |
| Keywords: | Asparagus officinalis L., ranked marketable yields, ranked disease tolerance |
| Abstract:
This trial was initiated at the 8th International Asparagus Symposium in 1993 to establish a systematic evaluation for yield, spear quality and disease tolerances of commercially available asparagus cultivars. Seeds of 45 asparagus cultivars were provided by seed companies and asparagus breeders for distribution to the participants of the trial. The seed suppliers designated the climatic zones in which their respective cultivars would perform best. The trials were conducted in 19 countries by 25 researchers who have selected the cultivars they are evaluating under a uniform experimental protocol. The cultivars UC 157 F1, Gijnlim and Jersey Giant are included in all of the trials as standards. The addresses of the active trial participants and their cultivar selections are presented. The ranking of marketable spear yields and the ratings for tolerance to Puccinia asparagi, Stemphylium sp. and Botrytis sp. are presented. | |
