Investigated variants, we carried out two experiments. 1st, we tested all of the accessions for the stenospermocarpy causal mutation within the gene VvAGL11 to know if it can be essential also in stenospermocarpic genetic backgrounds diverse from Sultanina. Then, we searched for single nucleotide polymorphisms involving Sangiovese and Corinto Nero by exploiting the transcriptomic information created by [52]. Validated IRAK4 Purity & Documentation variants have been finally tested on extra clones and accessions of Sangiovese/Corinto Nero and on the other genotypes.VvAGLGenotyping using the CAPS-26.88 marker confirmed that the Sultanina accession utilised within this study had the point variation (G T) causing the stenospermocarpy-associated Arg197Leu substitution in the VvAGL11 gene. All the other accessions had been homozygous for the seeded allele (G/G), with all the only exception of Aspirant. This accession was genotyped many times for the SNP position, corroborating the G/T genotype. Such polymorphism differentiated Aspirant from its seeded counterpart, Liseiret (data not shown).Table four Cross-pollination of Trebbiano Toscano and Nebbiolo with Corinto Nero pollen.
