Abstract

To determine the value of phenotypic variability of populations of different origins, two DH varieties (GK Delibab, GK Szindbad), a DH variety candidate (Ambitus) and two conventional winter wheat varieties (GK Istvan, GK Kincso) were compared for seven agronomic traits. The aim of the study was to find out if values of phenotypic variability of theoretically homozygous DH varieties are lower than variability of not homozygous traditional varieties, which have some genetic variation. On the basis of our analysts it can be established that there is no obvious difference in the variability of examined characters (plant height, spike length, spike width, spikelet length, spiklet width, number of node/spike and number of seeds/spike) of populations of different origins. The value of coefficients of variations (CV) ranged between 5-10%, which is characteristic for the balanced population. Only the value CV of seed-number/spike was higher. In conclusion, it appears that the examined populations of different origins cannot be separated by the value of variability.
