Apricot improvement

The object of the research was to improve the marketing possibilities for apricot as a fresh fruit and in food processing. Selected apricot varieties were exchanged between the participants for assessment of their performance on a range of sites, for exploitation of the existing genetic variability. A collection of reference varieties was completed and an investigation concerning floral compatibility of the main varieties was initiated. Hybridization was carried out for the creation of new genetic variability for further selection. An important subject considered was the methodology of selection and the problem of sampling to take into account fruit quality characters. A protocol was adopted for a common approach by the participants to the characterization of quality of preharvest and postharvest fruits. Modified atmosphere preservation, through the use of semipermeable film, appears to be a promising approach to the postharvest problem of rapid maturation of fruits. With respect to pathology, identification has been made of the various strains of Agrobacterium tumefaciens, Pseudomonas and Xanthomonas prunil, found in different countries. A systematic investigation of the resistance or susceptibility to sharka virus of the cultivated varieties has been initiated. The selection test is being optimized to determine the genetic mechanism of resistance to disease. The current situation gives the opportunity to reinforce the efficiency of breeding and selection programmes.
