Abstract
The long pepper (Capsicum annuum L.) has a high nutritional value, being an important source of vitamins (C, A, E, B, etc.). In Romania, it is cultivated on about 1000 ha, especially in Dolj, Olt, Arad, Brăila, Ialomița counties.
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 Sandy Soils, research was carried out in the period 2020-2022 regarding the variability of the main quantitative characters in the long pepper genotype L-28. Fruit weight (g), fruit diameter (cm), pericarp thickness (mm) and shape index were analyzed.
The results obtained differed according to the climatic conditions of each year of the study.
The registered biometric data were statistically processed, calculating for each analyzed character the mean (x̄), the standard deviation (s), the coefficient of variability (s%), the range of variability (k = x̄±s). 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%=17.30; fruit diameter s%=14.74; pericarp thickness s%=15.52; shape index s%=17.46). The current climatic conditions are increasingly leaving their mark on the quantitative characteristics of the pepper grown in the southwestern area of Romania, the improvement of this species gaining particular importance in this context.
Following the study, it was highlighted that the L-28. long pepper genotype represents a valuable material in the breeding process of this species.
