SNP markers reveal relationships between fruit paternity, fruit quality and distance from a cross-pollen source in avocado orchards

Abstract Cross-pollination can improve fruit yield, fruit size and nutritional quality of many food crops. However, we rarely understand what proportions of the crop result from self- or cross-pollination, how cross-pollination affects crop quality, and how far pollen is transported by pollinators....
