Comparative analysis of baking qualities of grain of winter rye varieties with various short-stem types

A comparative assessment of winter rye varieties with recessive polygenic and dominant monogenic short-stem types was carried out with respect to processing and baking qualities. It is shown that dominant short-stem varieties are significantly inferior to varieties with a recessive type in grain test weight, starch content, volume yield of pan bread, crumb porosity, and staling rate, but are significantly superior to them in water extract viscosity and form ratio of hearth bread. Differences are found in the content of amylose and amylopectin, their effect on the baking properties of rye grain is shown. The importance of creating low-amylose rye varieties with a better baking quality is pointed out.
