At Research Station for Fruit Growing Constanta isthe National Peach Collection with 855 genotypes from worldwide. Between 1981-2012, our peach breeders sorted thebest genitors and made a lot of hybridizations, than they obtained thousand and thousand of hybrids. During the time,31 new peach, pavie, nectarine and brugnone cultivars are registered to Bucharest ISTIS and this new biologicalmaterial enriches and diversifies the Romanian assortment. This paper presents seven new cultivarsKey words: Prunus persica (L) Batch, dwarf, fruit quality, processingINTRODUCTIONPeaches and pavies are appreciated for theirnourishing and therapeutically qualities andare recommended for fresh consumption andfor processing (Delgado, 1992; Bargioni,Pisani, 1993; Cepoiu, Manolache, 2006).Thousand and thousand peach cultivars are inthe world and annually, the breeders obtainnew varieties (Monet, 1990; Fraccaroli,Bargioni, Febi, 2000; Sansavini, 1991;Dumitru, Cepoiu, Stanica, 2001).MATERIAL AND METHODThe biological material is representing byseven new cultivars: ‘Cecilia’ – registered in2000; ‘Raluca’ and ‘Catherine Sel.1’ – omologatedin 2001; ‘Florin’ and ‘Filip’ – in2002; ‘Craita’ – in 2003; ‘Monica’ – in 2007.The American cultivar ‘Redhaven’ – registeredin 1964 in the Official Romanian BreedingCultivar List of Plant was control of thisexperiment.197The rootstock utilised was ‘Tomis 1’, whichwas registered in 1997 and it was obtained inour station by Dr. Alexandra Indreias.The orchard density was 833 trees / ha, forstandard trees (4/3 m) and 2222 trees / ha fordwarf trees (3/1.5 m).The trees were observed from the phenollogicalpoint of view. There were made biometricalmeasurements on fruits and trees;physico-chemical analyses on fruit; appreciationson productivity, behavior to the attack ofmain diseases and parasites, etc.The crown form was the improved vase.RESULTS AND DISCUSSIONS‘Redhaven’ is the American cultivar whichwas introduced in Romania in 1964. After 49years, this variety persists to be cultivated inour peach-orchard. It is the control of thisexperiment (Photo 1).
