Effect of genotype and phenological stages on the accumulation rate of dry matter in wheat

Journal of Animal & Plant Sciences, 2020
Considering that wheat occupies a primary place in human food, it is important to find varieties of wheat that, in addition to their high yields, are characterized by high nutritive and mineral qualities. The aim of this study was to determine dry matter content in genetically divergent wheat varieties, to identify varieties with a higher dry matter ...
