[FR] "Hérédité de plusieurs caractères d'importance agronomique chez l'amanier". Au cours de ce travail nous avons étudié quatre caractéristiques de l'arbre (date de floraison, densité de fleurs, productivité et date de maturation) et cinq caractéristiques du fruit (poids de l'amandon, dureté de la coque, pourcentage d'amandons, et amertume de l'amandon) dans une famille de 165 descendants d'un croisement entre la variété d'amandier [P. dulcis (Mill.) D.A. Webb] française 'R1000' ('Tardy Nonpareil' x 'Tuono') et la variété espagnole 'Desmayo Largueta' sur 3 années. L'identification des allèles d’incompatibilité a été étudiée grâce à la technique de la PCR. L'hérédité des caractères quantitatifs et qualitatifs a été étudiée et les implications dans l'amélioration variétale de l'amandier sont discutées.
[EN] Four tree traits (flowering time, flowering density, productivity and ripening time) and 5 fruit traits (kernel weight, shell hardness, kernel percentage, double kernels and kernel bitterness) were studied in an almond [P. dulcis (Mill.) D.A. Webb] progeny of 165 seedlings, for 3 years. This progeny comes from a cross between the French selection 'R1000' ('Tardy Nonpareil' x 'Tuono') and the Spanish cultivar 'Desmayo Largueta'. In addition, incompatibility alleles were identified using a specific S-allele PCR. The inheritance of the quantitative and the qualitative traits in this progeny is described and the implications for the almond breeding programmes are discussed.
