A winter wheat assortment comprising 190 varieties of different origins was sown on the chernozem of Caracal in the fall of 2023. Based on the observations underlying the characterization of wheat plants according to the UPOV (The International Union for the Protection of New Varieties of Plants) guide, distributions were made for several characters, namely: plant habit, frequency of plants with recurved flag leaves, earing date, plant height, ear compactness (density), awn length, ear length, ear shape in profile.
For the characters determined by measured values, the coefficient of variability was calculated to highlight the presence or absence of stability. The same characters were also evaluated based on the box-plot to highlight the existence of outliers or extreme values; values that deviate significantly from all the determinations made. Also, for each score for the characters mentioned above, new examples were added to simplify subsequent determinations and to broaden the base of reference varieties. The determined variability can be the basis of the wheat breeding program for the selection of parents.
