“…This clearly indicated the reverse relationship between protein content and 100 seeds weight. This conclusion was in agreement with that of Saxena et al (1987) on pigeonpea, Kaushik et al (2007) on Jatropha curcas and Afzal et al (2003a, b) on mungbean. It was found that investigated accessions had significant variation in protein content.…”

Eighteen L. inconspicuous accessions collected from different countries were evaluated for variations of seed weight, seed protein content, and electrophoretic patterns of the total seed proteins analyzed under reducing conditions. They exhibited a reasonable genetic variability for the evaluated traits. This genetic variability revealed that improvement through simple selection for these traits is possible. The variation between the seed size of this accessions was attributed to the development process or the life cycle of the plant, and the environmental condition to which the mother plant is exposed. On the other hand, the variation in protein content among the different accessions may be due to genotype and/or seasonal influences. The relationship between protein content and 100 seeds weight in the evaluated accessions was reversible, the accession showed the lowest quantity of the total seed proteins was the accession that exhibited highest weight of 100 seeds and nearly vice versa. Each accession gave a different electrophoretic pattern except the two accessions collected from Iran, exhibited an identical one. The difference in 100 seed weight and total protein content of these accessions indicated that they are not genetically identical. The variation in the electrophoregram of the evaluated accessions located in the bands with molecular weight more than 98 kDa, the heavy subunits of alpha-lathyrin subunits and the region molecular weight around 70 kDa. The results of cluster analysis based of SDS/PAGE under reduction conditions indicated that genetic diversity between Turkish, Syrian, and Iranian and Australian accessions is pronounced, and Turkish accessions are closer to both Syrian and Iranian accessions than the relation between Syrian and Iranian. This suggested that crosses between the Iranian and Syrian accessions could create more genetic variability than crosses with Turkish accessions. The distribution of Turkish and Syrian accessions between more than one clusters revealed that genetic diversity and geographic distribution were independent of each other. PCA showed that all accessions were separated on the first principal component, indicating that the accessions showed a good association, due, probably, to parallel evolution.Key words: 100 seeds weight, Protein analysis, multivariate analysis, germplasm characterization IZVLEČEK ANALIZA GENETSKE VARIABILNOSTI AKCESIJ GRAHORJA (Lathyrus inconspicuous (L.) S SDS POLIAKRILAMIDNO GELSKO ELEKTROFOREZOOsemnajst akcesij grahorja (L. inconspicuous L.), zbranih iz različnih držav, je bilo ovrednoteno glede na variabilnost mase semen, vsebnost semenskih proteinov in elektroforetskih vzorcev celokupnih semenskih proteinov analiziranih v reducirajočih razmerah, ob prisotnosti reducenta. Ovrednotene lastnosti so pokazale pričakovano genetsko variabilnost na osnovi katere je možna preprosta selekcija.

“…In our study, CP content was significantly and negatively correlated (r= −0.17**) with seed weight. In general, associations between CP content and seed weight have been found to be absent or weakly negative in grain legumes [25][26][27][28] and in Cajanus x Atylosia crosses [29]. These results clearly demonstrate that the relationships between seed weight and mineral and CP content vary across species and are mostly nonsignificant in grain legumes.…”

In order to increase knowledge of seed nutritive value and to demonstrate its relationship in common vetch (Vicia sativa L.) germplasm, 388 common vetch accessions were grown under field conditions in 2008-2009 growing season in Bursa province of Turkey. Seeds were analyzed for seed minerals (Ca, Cu, Mg, Mn, P, S, Zn and K) and crude protein (CP) content. The accessions were grouped according to testa and cotyledon color and seed size, and the results were evaluated by analysis of variance to determine relationships between minerals and CP content, testa and cotyledon colors, and seed weight. In general, there was no significant difference between testa colors or cotyledon colors in minerals and CP content. However, seed weight was closely associated with minerals and CP contents in this study. Analysis of variance and correlation analysis showed that seed weight was closely associated with some minerals and CP content. The small seeds had significantly higher Ca, Cu, Mg, Mn, S, Zn and CP contents than medium and large seeds.

“…No interactive effect between the seed mass and the crude protein content could be detected. Saxena et al [17] reported a highly significant negative correlation between seed size and protein content in high-protein lines of pigeon pea. Brunsgaard et al [18], in studies with 31 pea samples, reported that the smaller seeds had significantly higher protein content, but only in comparison with the largest seeds.…”

The seeds of 15 Polish pea varieties contained from 221 to 281 g/kg crude protein with a mean of 240.2 +/- 3.5 g/kg dry matter (DM). The weight of 1000 pea seeds, depending on cultivar, ranged from 209.4 to 280.4 g. No interactive effect between the seed mass and the crude protein content was detected. The highest significant negative correlation between weight of seeds and dietary fiber content was r = -0.815XX. The content of dietary fiber ranged from 161.5 to 209.9 g/kg with a mean of 187.9 +/- 3.8 g/kg. The mean gross energy of seeds was 18.1 +/- 0.28 MJ/kg. Amino acid composition of all the cultivars was similar, which was indicated by a similar index of essential amino acids (EAAI) of about 69.7 +/- 0.25. Trypsin inhibitor content in seeds was from 2.83 to 7.32 TIU/mg and the content of phytates ranged from 6.32 to 13.36 mg/g DM. The mean content of polyphenols and flavanols in analysed pea cultivars was 0.92 and 0.46 mg/g, respectively. In the seeds of most cultivars little or no pyrimidine glucosides, i.e. vicine and convicine, were found. The overall mean oligosaccharide content was 64.3 +/- 1.8 g/kg, of which alpha-galactosides were 46.8 +/- 2.0 g/kg. The antinutritional factor content was not significantly correlated with protein content. No statistical relationship was found between crude protein and dietary fiber content. It was observed that pea cultivars with higher trypsin inhibitor activity contained significantly less flavanols (r = -0.607X) and alpha-galactosides (r = -0.617X). The varieties with higher seed content of dietary fiber contained the highest amount of alpha-galactosides (r = 0.514X).
