| Abstract:
In apricot flowering intensity is negatively affected by flower abortion which occurs from endodormancy to bloom. Excessive abortion is frequently recorded on susceptible cultivars in the northern part of the Mediterranean basin. Global warming is likely to increase the importance of the mechanism involved in abortion. For these reasons the inheritance of the floral abortion trait was studied through the analysis of segregant progenies grown in different climatic conditions. A genetic control of this trait was clearly demonstrated and an assumption of quantitative inheritance seems plausible. | |
