The aim of the study was to check the breadmaking quality of different varieties of winter rye, especially population variety Amilo, which is known for its low enzymatic activity and was not thoroughly examined in comparison to the oldest registered polish variety Dańkowskie Złote, and to several other new varieties. The varieties displayed low but varying enzymatic activity and diversified chemical composition, water absorption, baking properties. Also bread loaves obtained from wholemeal flour differed in quality, moisture loss and crumb hardening. Wholemeal from population variety Amilo contained the highest level of pentosans (12%) and displayed highest water absorption (61%), the obtained bread had good volume and crumb with the lowest tendency to drying (1%) and hardening (2 kG). Population variety Kier had lowest amounts of protein (7.7%), level of pentosans lower in comparison to Amilo and lowest water absorption of wholemeal (56.4%). In this case the loaves were low in volume, quickly lost moisture (2%) and staled (4.5kG).
