A comparative study of some local genotypes with commercial cultivar of black elder (Sambucus nigra L .) regarding vegetative and reproductive traits

Th e main goal of this study was to evaluate three black elder (Sambucus nigra L.) genotypes (“Prigorje”, “Korčula”, “Zagreb”) and compare them with cv. Haschberg as standard cultivar. Diameter of inflorescences, cluster mass, berry/stem mass ratio, mass of 10 berries and SSC were higher in season 2014 than in season 2015, while length of one-year-old shoot and flowering density showed no significant differences. Interaction between season and genotype (S × G) was not significant for any of studied parameters. Genotype “Korčula” had significantly smaller diameter of inflorescence (11.26 ± 1.5 cm) than genotypes “Prigorje”, “Zagreb” and cv. Haschberg (16.81 ± 2.38, 18.05 ± 2.39, 17.5 ± 2.23 cm, respectively). Genotype “Korčula” (0.09 ± 0.03 fl owers·cm-1) had significantly smaller flowering density than genotypes “Prigorje”, “Zagreb” and cv. Haschberg (0.15 ± 0.07, 0.15 ± 0.04, 0.16 ± 0.04 fl owers·cm-1, respectively). Genotype “Korčula” had signifi cantly smaller cluster mass (23.35 ± 10.71 g) than genotypes “Prigorje”, “Zagreb” and cv. Haschberg (54.07 ± 22.09, 56.24 ± 22.76, 67.29 ± 24.56 g, respectively). Cv. Haschberg had significantly higher mass of 10 berries (1.35 ± 0.2 g) than genotypes “Zagreb” (1.15 ± 0.17 g) and “Korčula” (1.14 ± 0.19 g). Genotype “Zagreb” had signifi cantly higher value of total soluble solids (10.23 ± 1.74 %Brix) than genotype “Korčula” (8.99 ± 1.89 %Brix). Among studied genotypes and cv. Haschberg no signifi cant differences were found for length of one- year-old shoot. Since no significant differences were recorded between cv. Haschberg and genotypes “Zagreb” and “Prigorje” in majority of parameters, these genotypes should be further evaluated for longer period in order to bring final conclusions about their commercial and breeding potential.
