TEKNIK OKULASI JERUK KEPROK BRASTEPU (CITRUS NOBILIS VAR. BRASITEPU) UNTUK MENGHASILKAN BIBIT BEBAS PENYAKIT CVPD

The occulation technique to propagate Citrus nobilis Var. Brasitepu in order to produce good quality seedling that is free from Citrus Vein Floem Degeneration (CVPD) is explained in this research. The method is conducted by using bud stick from a healthy citrus Brasitepu plant and is then occulated via buddingmethod into lemon (Citrus aurantium) mother trees. The research is conduted in Bukit village Brastagi North Sumatra, Indonesia. Optimum conditions of the occulation methods have been obtained to produce good quality seedling of Citrus nobilis Var. Brasitepu. The growth characteristics of the seedling are known. Analysis of the DNA using RAPD-PCR method has confirmed that all new seedling produced in the occulation propagation method are healthy and free from CVPD.
