Abstract:
To compare two training systems and three red currant cultivars ('Red Poll', 'Rovada', 'Tatran') a trial was carried out in Switzerland in Bruson at 1100 m a.s.l. The considered training system for red currant production were: i) the traditional cordon training system (palmette system) with 3 not removed cordons (main branches) and 15 to 20 medium sized lateral braches per plant and ii) the V-training system with constantly renewed cordons, i.e., cordons were removed after 3 years at their basis (no permanent wood) and every year, 3 new cordons were established in order to obtain 2- and 3-year-old cordons producing fruits (V-system). The results over 7 years revealed that the V-training system had little influence on yield, cluster attributes and fruit quality, but a very positive incidence on the picking efficiency with 11% more fruits harvested per hour and on training investments with 15% less training hours. The economic performance of the new V-system was in average of the three cultivars 13% better than the traditional cordon system (palmette). 'Rovada' and 'Tatran' were more productive than 'Red Poll', mainly due to a higher number of clusters per plant. The economic performance was best for 'Rovada' and 'Tatran' grown in V-system.
