Somatic variants for seed and fruit set in grapevine

BMC Plant Biology

Table 5 Outcome of emasculation trials. Numerator and denominator indicate bunches that set fruit after treatment and covering and starting inflorescences, respectively. Occasional normal seeds from the bunches in boldface were put to germinate and the seedlings were genotyped with microsatellite markers
