<strong>potato</strong> varieties <strong>of</strong> Potato Research <strong>and</strong> DevelopmentStation Targu Secuiesc had been homologated.Materials <strong>and</strong> MethodsAll varieties are obta<strong>in</strong>ed by sexuat hybridizationfollowed by <strong>in</strong>dividual clonal selection, accord<strong>in</strong>g tothe classical scheme <strong>of</strong> <strong>potato</strong> breed<strong>in</strong>g – 12 years 3 .The ma<strong>in</strong> steps <strong>of</strong> work<strong>in</strong>g method were:-Established <strong>of</strong> genitors accord<strong>in</strong>g to physiological <strong>and</strong>technological qualities <strong>of</strong> tubers with dest<strong>in</strong>ation forprocess<strong>in</strong>g;-Sexuat hybridization, followed by all steps: seedl<strong>in</strong>gs,vegetative populations, descendants, comparative cropsfor completion (3 years <strong>in</strong> the network <strong>of</strong> <strong>research</strong> units<strong>and</strong> 3 years <strong>in</strong> the network <strong>of</strong> National Institute for test<strong>in</strong>g<strong>and</strong> Registration <strong>of</strong> Varieties / ISTIS) <strong>and</strong> selection forma<strong>in</strong>ta<strong>in</strong><strong>in</strong>g <strong>in</strong> the field <strong>of</strong> clonal selection on over 1000m a.s.l. (Red Water);-Homologation, obta<strong>in</strong><strong>in</strong>g license <strong>and</strong> registration <strong>in</strong>the National List <strong>of</strong> Cultivated Varieties.All three mentioned varieties have a high yieldcapacity, have a starch content over 18%, are resist<strong>in</strong>gto <strong>potato</strong> cyst nematodes (Globodera rostochiensis),<strong>and</strong> black wart (Synchitrium endobioticum) <strong>and</strong>viruses. The starch content <strong>and</strong> process<strong>in</strong>g quality weredeterm<strong>in</strong>ed <strong>in</strong> the laboratories <strong>of</strong> SCDC TarguSecuiesc, resistance to <strong>potato</strong> cyst nematodes atFagaras Centre, resistance to black wart at PojorataCentre Suceava <strong>and</strong> resistance to viruses at virologyLaboratory (I.N.C.D.C.S.Z. Brasov).<strong>Results</strong> <strong>and</strong> DiscussionsPotato variety COVALGenitors (BOBR X SUPER)Morphological characters: Tubers have round –oval shape. Color <strong>of</strong> sk<strong>in</strong> <strong>and</strong> pulp is yellow. Stems areerect. Leafs are semi compact with middle size foliols,green clear. Flowers are white <strong>and</strong> big.Physiological characteristics: The vegetationperiod is 90 – 100 days (middle late variety). It isresistant to PVY <strong>and</strong> nematodes (Globoderarostochiensis) <strong>and</strong> middle tolerant to late blight(Phytophthora <strong>in</strong>festans (Mont.) de Bary).Cul<strong>in</strong>ary quality: It has a good cul<strong>in</strong>ary quality(group B). It is recommended for consumption dur<strong>in</strong>gautumn <strong>and</strong> w<strong>in</strong>ter.Yield capacity; It has a high yield capacity (47.8t/ha).Zon<strong>in</strong>g: Coval variety is recommended for veryfavorable zones <strong>of</strong> <strong>potato</strong> production.Potato variety REDSECGenitors (M.P.I. 61-516-20 X CERTO)Morphological characters: Tubers have roundshape. Color <strong>of</strong> sk<strong>in</strong> is red <strong>and</strong> color <strong>of</strong> pulp is yellow.Stems are middle to big size <strong>and</strong> are semi erect. Leafs 29
