VARIABILIY OF NUMBER OF SPIKELETS PER SPIKE IN WHEAT CULTIVARS (TRITICUM AESTIVUM L.)

摘要

In this paper was analyzed number of spikelets per spike in 20 genetically divergent wheat cultivars originated from different breeding centers in Serbia. Wheat cultivars were grown in two years which characterized different climatic condition. In both years samples of 60 wheat plants (20 plants in 3 replications) were analyzed in full maturity stageFor improving different traits we need conduct special selection of parents after analysis of expression of certain traits.The differences in average values for number of spikelets per spike in studied cultivars were determined. The variability of number of spikelets per spike was established The average number of spikelets per spike for both year of growing, varied from 20.91 in cultivar Danica to 24.31 in cultivar Gruza.
