Molecular markers are widely used because of the wide range of applications. The identification<br />
of the varieties <strong>and</strong> clones of Pinots by microsatellite method according to the literature, present<br />
difficulties Hocquigny et al (2004) carried out SSR analysis between Pinots. Polymorphism<br />
analysis between ‘Pinot’ clones revealed that 65% shared the most frequent genotype. Moreover,<br />
the variant clones showed at least 96% similarity <strong>with</strong> this genotype. Based on our former<br />
experiences 7 Pinot gris, 4 Pinot noir clones <strong>and</strong> Pinot blanc were analysed in 16 (VVS2,<br />
VMC5E9, VMC3D12, VVIM10, VMC5G8, VMCNG1E1, VMC1F10, VMC2H4, VMC8A7,<br />
VMC7G3, VVMD28, VrZag21, VrZag79, VMC1C10, VrZag25, Scu06vv) microsatellite loci. A<br />
dendogramm was constructed using Jaccard index for the estimates of genetic similarity between<br />
pairs, <strong>and</strong> average linkage for clustering.<br />
Based on our results, it can be established, that the Pinot clones all showed high similarity. The<br />
Pinot gris clones bred in Badacsony, Hungary (B. 10, B. 10/5, B. 10/10) formed a group <strong>and</strong><br />
showed the highest similarity <strong>with</strong> Pinor gris 34 from Romania. The other Pinot gris clones<br />
formed another group <strong>with</strong> Pinot noir C-162. These clones all originated from western Europe<br />
(Germany, France). These genetic differences could be traced back to the different geographical<br />
origin of the different clones.<br />
