SELF-COMPATIBILITY EXPRESSION IN ALMOND BY POLLEN TUBE GROWTH

Pollen tube growth has been an important criterion for self-compatibility evaluation in almond. However, the success of pollen tube growth seems to be modulated by genetic and environmental factors which produce a not clear-cut separation between a successful and an unsuccessful pollination in the different genotypes. Pollen tube growth was evaluated after selfing the seedlings from the cross G-4-3 (SfS11) × ‘Marcona’ (S11S12) and the individuals were rated according to their self-compatibility index. The seedlings had different levels of compatibility, not allowing a clear qualitative separation between self-compatible and self-incompatible genotypes neither their classification in relation to the presence or not of the Sf allele. Consequently, the correlation between pollen tube growth and self-compatibility may be related to the presence of pseudo-self-compatibility in almond and to the effect of QTLs affecting the expression of self-compatibility.
