Table 2 Number of seeds that were recovered from open-pollinated Corinto Nero berries in 2016 and in vitro germinated to generate plantlets for ploidy level analysis and genotyping. Seedlings were obtained from 50 non-floating Sangiovese seeds with the only objective to calculate their germination rate

From: Somatic variants for seed and fruit set in grapevine

  Total seeds Normal seeds (non-floating in water) Potentially viable seeds (%) Seeds cultivated in vitro Germinated seeds Germination rate (%)
Sangiovese (clone R24) 429 402 93.7 50 27 54.0
Corinto Nero 629 174 27.7 165 85 51.5
