RESEARCH ON THE BEHAVIOR OF THE LONG PEPPER GENOTYPE 'BOGDAN' (CAPSICUM ANNUUM L.) IN SANDY SOIL CONDITIONS AT DĂBULENI RDSPCS

Abstract

Among the vegetable species, the long pepper (Capsicum annuum L.) is one of the most important crops globally, due to its flavor, high nutritional value, high content of vitamins (C, A, E, B, etc.) as well as an excellent source of natural colorants and antioxidant compounds (Howard et al. 2000). The success of long pepper cultivation is conditioned, to a large extent, by the cultivar used. In this sense, at Dăbuleni Research-Development Station for Plant Culture on Sands, research was carried out in 2023 regarding the variability of the main quantitative characters in the long pepper genotype 'Bogdan'. Fruit weight (g), fruit diameter (cm), pericarp thickness (mm) and shape index were analyzed. The registered biometric data were statistically processed, calculating for each analyzed character the mean (x̄x̄), the standard deviation (s), the coefficient of variability (s%), the range of variability (k = x̄ ± s), frequency of individuals (%).
The calculation and analysis of variability showed, on average, over the three years of the study, a medium variability for the characters analyzed (fruit weight s% = 24.35; fruit height s% = 13.06; pericarp thickness s% = 20.97; shape index s% = 15.84). The statistical analysis of the recorded data showed that for the long pepper genotype 'Bogdan', they are uniform in terms of the variability of the main characters, the coefficient of variability having high and medium values for most of the analyzed characters, and it represents a valuable material for the improvement of this species in the conditions of sandy soils from the south of Oltenia.
