Abstract
Five experimental hybrids (1 pentaploid, 3 tetraploids and 1 diploid) were planted in the field following a randomized block design with 4 repetitions, 2 for spring and 2 for autumn harvesting.
Hybrids were evaluated for yield and spear thickness during autumn 2020, spring 2021 and autumn 2021, and flavonoids content during autumn 2020 and spring 2021. Significant differences were found among hybrids for yield and spear thickness, being the interaction season harvesting-hybrid significant.
The performance of hybrids was different in autumn and spring.
The pentaploid hybrid had a yield significantly higher than the rest in autumn and had one of the highest yields in spring.
Regarding flavonoid content, seven different flavonoid types were found.
The flavonoid rutin was the most present ranging from 64.4 to 95.9% of the total content.
Variation among hybrids for all flavonoid was observed, the presence of some flavonoids being null in some hybrids.
Non-significant differences between harvesting season and non-significant interaction season-hybrid were detected.
The pentaploid hybrid showed the best flavonoid profile.
Therefore, their spears are expected to have a higher antioxidant activity, due to the synergistic action between flavonoids of different nature.
