The study on the characteristics of development and seed setting of different spikelet and floret positions was important for the realization of big - spike - cultural - goal with more spikelets and grains. with both the winter type ( wv ) and spring type ( sv ) varieties sown at different dates, it was found that the greater seed setting capacity of spikelets resulted in more grain number of spike. the trend of differences in grain weight per spikelet between the different sowing dates and varieties was similar to that of grain number. the correlation between the average grain weight of middle spikelets and lower spikelets and the grain weight per spike was highly significant. the environmental changes resulted from different sowing dates mainly effected the middle spikelets development, even though the differences between wv and sv were represented in every spikelet positions. the grain weight on the second floret position was most sensitive to the development status of wheat plant and environmental changes, and could represent the yielid potential of the whole spikelet. the results showed that the enhancement of seed setting of the middle spikelets ( from 5th to 15th ) and the grain development from the first to third floret positions was a key to realize big - spike and grain
