EVALUATION OF SOME APPLE ELITES WITH GENETIC RESISTANCE TO DISEASES, CANDIDATES FOR OBTAINING NEW CULTIVARS

Abstract

The researches performed at the Voinesti Research-Development Station for Fruit Growing have taken into consideration the highlight of the performance characteristics of some apple elites with a genetic resistance to diseases, obtained from hybrid combinations performed in the period 2004 – 2005. The apple elites, candidates for obtaining new cultivars, resulted from the selection of the 3260 apple hybrids, obtained from the initial breeding material with a great genetic diversity.
The five selected apple elites have shown genetic resistance to diseases, fruits with a superior quality and correspond to the objectives that must be met by a cultivar.
The elites obtained through sexual hybridisation from the ‘Goldenspur’ x ‘Florina’ had fruits that have an average above 160g, yellow or yellow-greenish colour and good taste. The elites obtained through sexual hybridisation from ‘Florina’ x ‘Idared’ have fruits that have an average of 160-180 g and covered up to ¾ of the surface with red.
The apple elites with a genetic resistance to diseases, candidates for varieties, obtained at SCDP Voinesti in the period 2004 – 2005 correspond to the producer’s requirements, sensitive to economic efficiency, with an increased production potential, with quality fruits that for sure will meet the consumer’s requirements, which are continuously increasing.
