Recently, it has been shown that the genetic composition of the intraspecific neighborhood can influence a plants investment in attracting pollinators. Specifically, plants surrounded by kin exhibit significantly larger floral displays compared to those grown with non-kin. This increased floral display in kin groups could enhance plant inclusive fitness by attracting shared pollinators to other nearby kin. To investigate this hypothesis, we conducted an experiment using the model plant species Moricandia moricandioides. We established an experimental population of 560 plants, divided into 80 groups of seven plants each. Half of these groups consisted solely of half siblings, while the other half contained a random sample of genotypes. We then measured pollinator visitation rates and female reproductive success. Our findings will provide the first experimental insights of the potential effect of kin selection on floral display evolution.
