Almond pollinator cultivar
Prunus dulcis (Mill.) D. A. Webb
Most almond cultivars are self-incompatible due to the gametophytic S-locus control system, making the selection of genetically compatible pollinator cultivars with overlapping bloom periods mandatory.
In the reference 83 varieties crop Almond, where this is mentioned in the description.
Almond self-incompatibility is driven by the S-locus, where the pistil produces S-RNases that block the growth of pollen tubes from the same cultivar. In commercial orchards, overcoming this barrier requires alternating rows of the primary cultivar with pollinator cultivars that must have identical bloom periods and genetic compatibility.
In addition to self-incompatibility, almond agronomy must account for cross-incompatibility, where certain pairs of cultivars are unable to fertilize one another. Pollination efficiency depends directly on the activity of insects transferring pollen between compatible genotypes, which dictates strict row spacing patterns in the orchard.
