BIOCHEMICAL CHARACTERISTICS OF SEEDS OF LUPIN (LUPINUS L.) FROM VIR COLLECTION
The article presents the results of studying the biochemical composition of seeds of samples of seeds from L. elegans H.B.K., L. nanus Dougl., L. ornatus Dougl., L. pubescens Benth. Protein from lupine seeds ranged from 33,9 to 49,7%. The highest protein content was insignificant (coefficient of variation (CV) from 4,7 to 5,3%). The oil content in the seeds of the studied samples was from 4,6 to 11,9%. The highest content of oil (8,6-11,8%) observed in L. pubescens. The content of the eleven fatty acids was determined. All samples showed a high content of unsaturated fatty acids (EFA) - from 88 to 91% of the total content of fatty acids. It showed that in the lupine seed oil of the studied species, the main fatty acids are linoleic (31-65,2%), oleic (14,6-48,1%), palmitic (8,3-19,7%) and linolenic (1,5-13,1%). An important indicator of the value of oil when used in nutrition is the ratio of linoleic and linolenic acid. The most interesting in this respect is L. nanus, for which this indicator is 4,5. The samples of L. nanus are characterized by the highest among the studied species, the content of oleic (32,3%) and linolenic (9,5%) acids, and the lowest - palmitic (12,6%) acids. As a result of the correlation analysis, the mean values of the correlation between the signs were revealed. There is a strong negative correlation between the oleic and linoleic acid content (-0,93). Samples with a high content of oil and protein were isolated. The greatest effect on the content of protein, oil and fatty has genotype, less effect - species. The best examples with high content of protein and oil (cat-1322 and 1917) were selected.
