THE BEHAVIOUR OF SOME PEACH CULTIVARS PERTAINING TO THE PEACH WORLD COLLECTION IN PEDOCLIMATIC CONDITIONS OF TIMISOARA AREA

Peach represents one of the most appreciated fruit tree variety of the temperate climate, which in the last 30 years has benefited of a special attention, fact that has led to the expansion of cultivated areas with this variety and to diversification of the assortment. Researches carried out in USA, Canada, France, Italy, Spain, even in our country had led to obtaining a large number of varieties with remarkable agro-productive characteristics. In the present work were studied 9 cultivars of peach pertaining to the Peach and Nectarine World Collection introduced and multiplied in Romania by Acad. Dr. Vasile Cociu. The cultivars originating from all continents have been planted in Timisoara in 2007 with the purpose of being tested in culture and naturalizing in Romania of some new foreign varieties. Regarding the fruit weight were evidenced 'Yinquing', 'Giala di Roma', 'Tardiva', 'Eureka' and 'Piros Magdalena'. In terms of % kernel were highlighted 'Giala di Roma Tardiva', 'Marqueen' and 'Gold Dust' cultivars with less than 7% kernel %. Concerning dry substances, the highest sugar content was registered in the fruits of following cultivars: 'Marqueen', 'Eureka', 'Yinquing' and 'Giala di Roma Tardiva'.
