Abstract

Developed and well organized seed production implies constant production of seeds of all categories and thus maintaining the level of genetic purity of wheat varieties. Three varieties of the Institute PKB Agroekonomik winter wheat, PKB Kristina, PKB Roksanda and PKB Rodika, of different value morphological characteristics of plants, level of fertility and grain quality characteristics were investigated. Each wheat variety was grown in three different variants of agritehnical conditions, adapted for obtaining three categories of seed plants: prebasic seed, basic seed and 1st generation certified seed. The prebasic seed category had the highest average values in both years of the experiment in the following examined traits: number of secondary shoots, number of spikelets in the spike and number of seeds per spike. The prebasic seed category had the highest number of spikelets in the spike which indicates that they develop on longer spikes than the other categories of seeds. Based on this characteristic, the prebasic seed category has the potential to form more seeds per spike than other investigated seed categories. The 1st generation certified seed category had the lowest number of seeds and the smallest seeds, because this seed category is produced in the highest density.
