AGROTECHNICAL AND BIOLOGICAL PROPERTIES OF SOME SOUR CHERRY CULTIVARS AND THEIR SUITABILITY FOR CULTIVATION IN CENTRAL POLAND
Cultivars: Schattenmorelle IR-2 (British type of Schattenmorelle), Koral (Polish), Debreceni Bötermö (Hungarian), Újfehértói Fürtos (Hungarian), Karneol (German), and Vowi (German) were examined for their biological and agronomical properties in 2006-2009. Debreceni Bötermö, Újfehértói Fürtös, and Karneol were the most vigorous when compared to other tested cultivars. High quality pollen, investigated in vitro and in vivo, was observed in Koral, Schattenmorelle IR-2, and Vowi, whilst that of the Hungarian cultivars and Karneol was poor quality. Schattenmorelle IR-2, Koral and Vowi had more fruits after self-pollination, when compared to Debreceni Bötermö, Újfehértói Fürtös and Karneol. Furthermore Vowi, Schattenmorelle IR-2, and Koral produced the highest yield, whereas Karneol and Újfehértói Fürtös gave the lowest. The Hungarian cultivars and Karneol are partly self-fertile, and while the other tested cultivars had a high degree of autogamy, they also set a lot of fruit after open pollination. Pollen of Schattenmorelle IR-2 and Koral increased fruit set significantly in the Hungarian cultivars. Finally, Debreceni Bötermö and Újfehértói Fürtös had the highest fruit quality and Vowi had the lowest.
