SOME BIOLOGICAL PROPERTIES AND FRUIT QUALITY PARAMETERS OF NEW SWEET CHERRY CULTIVARS AND PERSPECTIVE SELECTIONS

During 2001-2010, the following cultivars from the breeding programme of the Polli Horticultural Research Centre of the Institut e of Agricultural and Environmental Sciences, Estonian University of Life Sciences were registere d: the apples 'Kaari', 'Kaimo', 'Karamba', 'Katre', 'Kikitriinu', 'Krista', and 'Liivika', the crab apples 'Kuku', 'Ritika', and 'Ruti', the sweet cherries 'Elle', 'Karmel', 'Piret' and 'Tontu ', the raspberries 'Aita' and 'Alvi', and the black currants 'Almo', 'Ats', 'Elo' and 'Karri'. Si nce 2004, applications for registration and DUS testing have been submitted for the new apple cultivar 'Els', pear cultivars 'Kadi' and 'Polli Punane', sweet cherry cultivars 'Anu', 'Ene' , 'Irma', 'Kaspar', 'Mupi', 'Polli Murel' and 'Tommu'. Apple, plum, sweet cherry, black currant and raspberry breeding programmes are going on as part of the public breeding program. Wi nter hardiness is the first-rate goal in all crops. In apple, breeding for scab resistance is no w the main task. In the nearest future, some new plum, apple and black currant cultivars will su pplement the breeding results of the institution at Polli.
