| Abstract: | In order to research the setting percentage and the grain weight of spring wheat, two varieties Longmai 26 and Kenda 4 were used. The results showed that the florets with highest setting percentage were located in lower part of spikelet, the spikelets with highest setting percentage were located in middle-lower part of ear, the highest weight grains lay on first or second place of spikelet, but the highest weight spikelets lay on lower position of ear. |
