| Popis: | International audience; The knowledge on the transmission of fruit quality traits has a great importance in order to optimize the inter-cultivar crosses design and to improve the efficiency of apricot breeding programmes. Four apricot progenies issued from different genetic origins were evaluated during two years; two apricot progenies cultivated in Avignon (France), one in Bologna (Italy), and other one in Murcia (Spain). Fruit quality characterization was based on physical measurements (fruit weight, colour, and firmness) and biochemical measurements (soluble solids content, and titratable acidity). Phenotypic datasets showed distribution of seedlings with regard to the parents, with a high variability for all analyzed quality parameters. An inter-annual variation was observed for the mean values of all the genotypes between the two years of the study, indicating the influence of the environmental conditions on fruit characteristics. Results indicated a quantitative inheritance of all quality traits in the apricot progenies indicating their polygenic nature. In general we observed in most cases a normal distribution of quality traits in the observed populations. However, in contrast to intermediate expected values between the parents, a large number of seedlings showed lower or higher values than their parents for many quality parameters. In this sense, results evidenced an extra genetic influence of the parents (the whole genetic background) on the transmission of fruit quality traits in apricot, which should be taken into consideration with inter-cultivar crosses design. |
