Description
Summary: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.
