Resumen:
With the aim of studying the productivity of seven all-male genotypes of green asparagus of Italianorigen (Italo, Zeno, Eros, Ercole, H-668,Marte and Giove obtained by CRA, Italia) versus the NorthAmerican control cultivar UC-157, a field trial initiated in 11/2006 via seedlings in the ExperimentalField of the Facultad de Agronomía-UNCBPA (36°48’lat. S - 59°51’ long W) was evaluated in itsfifteenth year of production. The following traits were evaluated: Total fresh commercial production(PFCT) in t.ha-1 and the corresponding production of long (22 cm) and short (17 cm) spears (PFC-Land PFC-C, respectively); Total number of spears (NTT), including waste, plus total commercial number(NTCT) and the corresponding number of long and short spears (NTC-L and NTC-C, respectively);unit weight (PPT-L); caliber distribution (J: Jumbo; XL: Extra Large; L: Large; M: Medium; S: Small; A:Asparagine); Waste (DE: Sprouted; MC: Unacceptably short; OD: Other defects). Analysis of varianceANOVA-LSD (P ≥ 0.05) was carried out. In overall mean performance, the set of Italian genotypesoutperformed UC-157 in t.ha-1and in spear number. The main defect was sprouting. Ercole, Gioveand Eros stood out for their productivity performance and quality. For caliber, Giove was the superiorgenotype, as observed in previous years.
