AB The aim of this contribution is the evaluation rye pentosans in the relation to protein content, Falling number, content of maltose and amylograph values. Population and hybrid varieties of rye were grown during 2003-2005. Trials were situated in three different locations of the Czech Republic - Hradec nad Svitavou, Krásné údolí and Staňkov. Content of pentosans varied between 6.60-9.21 %. The highest content of pentosans (average of the three years and three locations) achieved the hybrid variety Picasso (8.11 %), which had the highest Falling number (235.8 s) and amylograph maximum (625.5 AJ), too. The location Hradec nad Svitavou (8.21 % pentosans) was the best and the year 2003 (8.34 % pentosans) was the most positive.The results were affected by soil and weather conditions which have influence on protein content. Between the pentosans content and the Falling number a high positive correlation (r = 0.523, P < 0.01) was found and nonsignificant negative correlations with protein content (r = -0.070) and amylograph maximum (r = -0.072). Remarkable difference in the Falling number and amylograph maximum between population varieties (Daňkovské nové a Selgo) and hybrid variety (Picasso) were found.
