THE GENETIC VARIABILITY IN TOMATO GENOTYPES L-11/53 AND V 5 GROWN IN PROTECTED SPACES

Abstract

The tomato genotypes (L-11/53 and V 5) were subjected to an analysis regarding the variability of the main quantitative fruit characters (fruit weight, fruit height, pericarp thickness). The registered biometric data were statistically processed, calculating for each analyzed character the mean (x̄), the standard deviation (s), the coefficient of variability (s%) and the range of variability (k = x̄ ± s).
The calculation and analysis of the variability of the characters studied in the tomato genotypes L-11/53 and V 5, revealed on average in the two years of the study a small variability for the height of the fruit (s% = 9.37% for L-11/53 and 7.52% for V 5) and medium for pericarp thickness (s% =16.59% for L-11/53 and 15.47% for V 5).
The values of the calculated statistical indices, of the characters taken in the study, require the continuation of the selection process in order to maintain them within the specific limits of variability.
