Variability of Grain Protein Content in Improved Upland Rice Genotypes and Its Response to Locations
To search for genetic resources of high grain protein content in upland rice, the variability and genotype × location interaction ofthe protein content was studied by a field experiment. The materials used were 10 improved genotypes and two reference uplandrice cultivars. The experiment was carried...

To search for genetic resources of high grain protein content in upland rice, the variability and genotype × location interaction ofthe protein content was studied by a field experiment.
