Marketable tuber yield stability in potato

In the paper was analyzed marketable tuber yield stability of eight foreign potato cultivars (Arosa, Rosara, Velox, Flavia, Satina, Hopehely, Goliath and Rioja) grown in Croatian production environments for three growing seasons (2003-2005), on four locations (Brinje, Varaždin, Velika Kopanica and Osijek). Results of marketable tuber yields and estimated stability parameters indicate that genotypes, which have a high stability, were not the highest-yielding genotypes. The highest-yielding cultivar was Hopehely, which could be recommended for high-yielding environments, and the most stable cultivar was Rosara. There is concordance between regression coefficient estimates and AMMI analysis.
