Evaluation of sweet and sour cherry cultivars useful in genetic improvement

Abstract

During 1999-2014 at RSFG Iasi were approved 28 new sweet cherry cultivars from which 25 with sweet taste and three with bitter taste. The sour cherry have been approved and patented three cultivars in the period 1978- 1994. The methods used to obtain new cultivars of cherry were selection of local cultivated flora, artificial hybridization, mass selections obtained by free pollination. As genetic resources were used sweet cherry collection (established and continuous collected during 1980-2006) with 550 genotypes and sour cherry collection (established and collected during 2000-2002) with 130 genotypes. The paper aims to assess six sweet cherry cultivars and four sour cherry cultivars that can be used as genitors in improving these both fruit tree species
