Conditional QTL Mapping of Wheat Main Yield Traits

Because the canopy traits showed be largely varied under different nitrogen application levels, so more information would be obtained by dissecting the gene expression of wheat canopy traits under different nitrogen application levels than that of unconditional QTL, which was important for regulating the canopy traits and improving the nitrogen utilization. Previous research only studied the unconditional QTL under one nitrogen application level, but there was no report on conditional QTL of nitrogen utilization. Therefore, this study carried out the unconditional and conditional QTL mapping of five canopy traits under the normal and low nitrogen application levels so that provide some references on nitrogen utilization and construction reasonable canopy at QTL/gene level.
