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.
