| Abstract:
The main objectives of this study were: (i) to determine genetic and phenotypic variability and broad-sense heritability for nine morphological characters and (ii) to analyze genetic and phenotypic correlation coefficients among several agronomic traits in some cabbage cultivars. Nine cabbage cultivars and hybrids were grown in the mountain of Zlatibor. Significant differences in genetic factors, environmental, and genotype x environment interaction were observed for all morphological characters. The lowest variation coefficient (CVg) was obtained for head leaf number (3.48%), while the highest was for stem weight (25.70%). Heritability coefficients were high and ranged from 32.97% for number of dead leaves to 97.74% for stem length. Coefficients of genetic correlation show that the most significant influence on head weight was exerted by the number of dead leaves (0.999**) and head diameter (0.762*). Genetic correlation for morphological characters showed higher values than the respective phenotypic values, which means that the influence of the environment on this relationship was significant. | |
