The almond selections evaluated had a late flowering period and low vigor. A loss of plant material at different stages of growth and development was observed. The trees had low branching and flowering was of poor quality during some years; which can be attributed to physiological and environmental effects. Expression of the self-compatibility trait, based on the rate of fruit set obtained in the absence of cross-pollination differed according to genotype, and differences were linked to the genetic background. The environmental effects on fruit set were important and showed variation between years. Production was not regular and yield obtained was low except for two selections: 'Lauranne' and (769x217)x16. Kernel size varied between selections and was generally small with an average of 1 g per nut. Similar results between selections in their behavior, reflects their genetic proximity with inbreeding effects.
