'Blanca de Tudela' and seed artichoke in Navarre
The artichoke, specifically the Blanca de Tudela cultivar, is the most traditional and deeply rooted horticulturist crop within the irrigated fields of Navarra, not so much because of heads production for fresh market or canning and frozen food industry, but because of stumps production, which supplies all Spanish production areas. Given the importance of the Blanca de Tudela artichoke cultivar in Navarre, due to its twofold use: heads and stumps, and the increasing introduction of seed artichoke cultivars in these areas, INTIA has taken a special interest in analysing the agronomic adaptation and behaviour of seed cultivars in our agroclimatic conditions. This paper analyses the precocity, yield and industrial yield of four seed cultivars in comparison with Selection ITGA of Blanca de Tudela: Lorca, Madrigal, Opera and Symphony. Also, samples of these cultivars were analysed to determine the total antioxidant capacity (TAC) and the content of free and total polyphenols, lutein and dietary fibre. Selection ITGA, a vegetatively propagated cultivar, was the earliest cultivar of those tested. All the seed cultivars were characterised by a late harvest as well as, in some cases, a high harvest concentration. Madrigal was the latest cultivar, but also the one with the highest yield. Selection ITGA and Symphony obtained the highest industrial yield. Selection ITGA reached the higher content in lutein and dietary fibre and Opera is the most interesting cultivar in terms of concentration in antioxidants compounds.
