Biochemical Assessment of Peas Pisum sativum Varieties

Seven peas (Pisum sativum L.) varieties different originated, i.e, X07P54, X06PWY, NDPO80138-B-2, CA1P, L020140, Wt6803 and Mir were studied. Biochemical assessment of fresh aboveground biomass and seeds of peas varieties were done. At the beginning of flowering stage the NDPO80138-B-2 and X07P54 were reported high levels for crude protein (22.33% and 21.87%), crude fibre (25.94% and 25.76%) and crude ash (10.39% and 9.47%). In technical maturity with high crude protein and crude fibre contents NDPO80138-B-2 (21.59% and 21.38%), X06PWY (19.95% and 21.36%), X07P54 (19.78% and 20.57%) and CA1P (19.60% and 22.53%) were distinguished; by calcium CA1P (2.09%), and by phosphorus Wt6803 (0.54%). More significant variability in phosphorus content (21.27%) and Ca:P ratio (25.65%) in fresh biomass was observed. The lowest coefficient of variation was found for crude fibre (5.43%), crude ash (7.81%) and crude protein content (9.00%). The variability of parameters in technical maturity was found low and ranges from 2.34% for crude protein to 9.27 for phosphorus. The green mass yield is positively correlated with the calcium content (r = 0.581), phosphorus (r = 0.316) and crude ash (r = 0.077) and the seed yield positive correlated with calcium content (r = 0.79). The relationships found between qualitative indicators could be used in the breeding programs of peas.
