To determine the agronomic performance of asparagus genotypes, a randomised complete block design trial (planted 16/11/11, density=23,810pl.ha-1, area=1690m2) was carried out in Azul (36°48´,lat.S?59°51´,long.W) within the framework of the ISHS?s Fourth International Asparagus Cultivar Trial, in which the following hybrids were harvested between 05/09/2018 and 14/11/2018 and the spears conditioned to two lengths (long=22cm, short=17cm): ?Italo?-?Vittorio?-?Eros?-?Ercole?-?Giove?-?Franco?-?Chino?-?Early-California?-?UC-157?-?Patrón?-?NJ-1189?-?NJ-1123?-?NJ-1192?. The following characters were evaluated: total fresh commercial productivity (TFP) and that of long and short commercial spears (CFP-L; CFP-S); total commercial spear number (TSN) and that of long and short commercial spears (CSN-L; CSN-S); mean spear weight (MSW); calibre distribution (CD): (J: Jumbo=>18mm; XL: Extra-Large=16-18mm; L: Large=12-16mm; M: Medium=9-12mm; S: Small:6-9mm; A: Asparagine=
