Abstract

Series of cultures of anthers from different genotypes of pepper (Capsicum annuum L.) were cultivated to determine their androgenic potential during the two-year research. Six pepper genotypes (Edita F1, Homera F1, Duga bela, Una, Amfora and Kurtovska kapija) were used in the research with different number of anthers as starting material. The anthers were isolated from pepper buds in appropriate developmental stage were cultivated on suitable nutrient media, following appropriate protocols. Bela duga and Edita F1 resulted in the formation of different number of androgenic embryos. As a final result, only one fully acclimatized androgenic plant (Edita_R1) of the Edita F1 was obtained. The content of photosynthetic pigments in ripe fruits from the androgenic plant Edita_R1 was analysed and compared to the same physiological parameters in ripe fruits from mother genotype Edita F1. The average content of chlorophyll a, chlorophyll b and chlorophyll a+b in the ripe fruits from the androgenic plant Edita_R1 was 2.27 mg/g fresh weight, 6.59 mg/g fresh weight and 6.12 mg/g fresh weight, respectively. The average content of chlorophyll a, chlorophyll b and chlorophyll a+b in the ripe fruits from mother genotype Edita F1 was determined as 2.37 mg/g fresh mass, 5.74 mg/g fresh mass and is 6.26 mg/g fresh mass, respectively. The average value of the content of carotenoids in the fruits of androgenic plant Edita_R1 was 6.28 mg/g fresh weight which was significantly higher as compared to 1.18 mg/g fresh weigh in the fruits of the mother genotype Edita F1.
