Comparation of production caracteristics of grapevine 'Moslavac' clone candidates

'Moslavac' je autohtona sorta vinove loze koja se uzgaja na području kontinentalne Hrvatske. Klonska selekcija sorte ʹMoslavacʹ započeta je 2010. godine. Odabrana su 32 klonska kandidata slobodna od gospodarski štetnih virusa koji su razmnoženi i posađeni u pokusni nasad.Na temelju ampelografske i gospodarske karakterizacije izdvojeno je pet klonskih kandidata koji su ušli u završni postupak ispitivanja što je osnova za njihovu registraciju. Kod pet klonskih kandidata koji su izdvojeni za završno ispitivanje provedena 2018. godine gospodarska i enološka evaluacija koja obuhvaća: utvrđivanje prinosa, sadržaja šećera i kiselina u moštu, pH vrijednosti mošta, te sadržaj aromatskih spojeva u moštu. Provedena je i mikrovinifikacija odabranih klonova te kemijska i organoleptička analiza vina. Uz navedeno proveden je i pokus sa redukcijom prinosa. Utvrđene su značajne razlike između promatranih klonskih kandidata u svim istraživanim svojstvima. Značajna razlike utvrđene su i u reakciji klonskih kandidata na redukciju prinosa.ʹMoslavacʹ is a native grape variety grown in the continental parto of Croatia. The proces of clonal selection of this variety began in 2010.A total of 32 clone candidates, free from economically harmful viruses, were selected and planted on the experimental plantation. Ampelographic and economical characterization was carried out, in order to separate the clones with the best properties. Five separated clone candidates entered the final examination procedure, which is the basis for their registration. For these five candidates, economical and enological evaluation was performed, which involves the assessment of yield, sugars, acids, pH value and content of aromatic compounds in must. Chemical and organoleptic wine analysis and microvinification of the selected clones will also be carried out.In the addition to the above mentioned studies, the yield reduction experiment was also carried out.Significant differences between observed clone candidates were determined in all investigated properties. Furthermore, remarkable differences were identified in the reaction of clone candidates on the yield reduction
