Abstract
Two trials were carried out in the Vega Baja del Segura (SE Spain coast) to study the earliness, yield and head weight of 26 clones of bull variant plants coming from a population of Violet de Provence artichokes.
Eleven clones were studied in a completely randomized experimental design with three plots per plant (Experiment 1). In another trial the remaining clones were observed in one single plot (Experiment 2). The plantation took place on 1st August.
The different clones began production throughout January or February.
In Experiment 1, the winter and final productions (production accumulated up to February 28th and up to the end of May, when harvesting was finished) were 656 g/plant (1.40 heads/plant) and 2,124 g/plant (5.77 heads/plant), respectively.
In experiment 2, these productions were 530 g/plant (1.10 heads/plant) and 2,350 g/plant (6.57 heads/plant). The head weight in the first trial was 463 g if only winter production was considered, and 366 g considering the whole production.
In Experiment 2, these head weights were 493 and 358 g.
We have also studied some clones of bull variant plants coming from a population of Blanca de Tudela artichokes in two other trials together with these.
Although the results are not comparable, the winter and whole productions of clones coming from Blanca de Tudela were larger, whereas clones coming from Violet de Provence yielded weightier heads.
