Abstract
The genotype variation was assessed for advancement of main stem spike development at the shooting phase in three cultivars and 43 strains of spring wheat bred in Poland. The plants were grown in hydroponic culture under controlled conditions of phytotron. Significant differences have been stated in development stage, earliness, and morphological structure of main spike, number of spikelets per spike and in the spike dimensions (length and width). The analysis of main spike development offers a tool for earliness evaluation and selection at the shooting phase. Preliminary evaluation of morphogenetic potential is possible at the shooting phase only for the most developmentally advanced strains.
