Abstract: Grain development on wheat spike is asynchronous. The grain number, weight and protein content in different spikelet positions significantly varied with wheat cultivars and nitrogen levels. The experiment with two cultivars and two nitrogen levels was conducted at Jiangsu Academy of Agricultural Sci

Key words: Wheat, Spikelet position, Grain position, Grain weight, Protein content, Spatial distribution
