To verify the compatibility behaviour of the almond cultivar ‘Francolí’ and to clarify its S genotype a combination of pollination tests, stylar ribonuclease and allele specific PCR analysis was used. ‘Francolí’ was released from IRTA's breeding programme in 1994, having been putatively raised from the cross ‘Cristomorto’ ( S 1 S 2 ) × ‘Gabaix’ ( S 10 S 25 ). This cultivar was also reported to be self‐incompatible but revealing only one S band in the zymograms after S ‐RNases analysis. ‘Francolí’ sets nuts after test crossing with two S 1 S 25 cultivars, having a different genotype from that earlier reported. ‘Francolí’ was also observed to be self‐compatible after selfing flowers in the field and in the laboratory. ‘Francolí’ was re‐assigned the S 1 S f genotype after test crossing, stylar ribonuclease and PCR data analysis. After microsatellite analysis, the self‐compatible ‘Tuono’ ( S 1 S f ) cultivar is suggested as the male parent of ‘Francolí’ instead of the earlier reported ‘Gabaix’.
