CLONE SELECTON OF AUTOCHTONES AND INTRODUCED VARIETIES IN THE OLD GRAPEVINE PLANTED AREAS OF SOUTH EASTERN AND EASTERN SERBIA AND PRELIMINARY CHECK OF THEIR HEALTH STATUS

selection of autochtones and introduced varieties in the old grapevine planted areas of Eastern and South Eastern Serbia and preliminary check of their health status.- Genetika, Vol. 43, No. 3, 465-475. Clone and sanitary selection of the grapevine has a fundamental importance in improving the quality and the quantity of the grape production in Serbia. In order to preserve the varieties of the old vineyards, the clone and sanitary selection has begun in 2006 in the South Eastern Serbia vineyard areas, 1048 grapevine plants have been examined in three distant vineyards and 60 grapevine plants have been separated that deserved attention based on their production characteristics. The selected plants have been tested serologically, with the ELISA method, to the presence of 4 grapevine viruses: Grapevine leaf roll-associated virus 1, Grapevine leaf roll-associated virus 2 and Grapevine leaf roll-associated virus 3 (GLRaV-1, GLRaV-2 and GLRaV-3), and grapevine fun leaf virus- GFLV. The infection level of the selected plants was between 10.5 % (vineyard III) and 22.2 % (vineyard II). We eliminated the infected plants among the selected ones and analyzed only the healthy ones in the 2008. Various potential 466 GENETIKA, Vol. 43, No. 3,465-475, 2011 variety clones have been selected for Prokupac, Pamid, Dimyat, Sauvigno
