For pairwise genetic differentiation, Kst revealed significant differentiation between Pantesco and both Grigio (Kst = 0.133, p < 0.001) and Ragusano (Kst = 0.313, p < 0.001), whereas differentiation between Grigio and Ragusano was low but slightly significant (Kst = 0.049, p = 0.038) ( Table S1 ).
