The pea (Pisum sativum L.) is one of the most important legumes and it is one of the oldest
subjects of breeding improvements. Planned breeding dates back to the 18 th century when Knight
performed the first cross breeding experiments on the pea plant. Since then, through systematic
breeding and selection pea species were segregated according to their usage for human or animal
consumption. The aim of this paper was to determine if there are differences in structure and
content of individual saccharides among the collected samples from pea breeding programs for
human and animal consumption. The analysis was conducted on green (immature) seeds of five
accessions of both pea types (human and animal consumption) with the HPLC method. No
significant differences were determined for α- galactosides (verbascose, stachyose and raffinose)
between the tested types. Significant differences in monosaccharaides and disaccharides content
in both pea types were determined through variance analysis. Accessions intended for human
consumption had double the content of sucrose compared to accessions intended for animal feed
with a significance level of p≤0.01. Types of peas for human consumption had a significantly
higher content of glucose than types intended for animals. The content of monosaccharides
fructose and galactose varied according to accession in both groups. The overall sugar content in
types for human consumption was between 13.42% and 19.28% in absolute dry matter (aDM).
The sugar content in pea types for animal consumption was between 7.83% and 9.93% in aDM.
The results confirm the assumption that humans have, through continual selection, influenced
the segregation of the two pea types according to purpose.
