Abstract: | Thirty-one European accessions of grass pea (Lathyrus sativus L.) originating from Italy, Spain, Northern France, Germany and Poland grown in the same soil-climatic conditions in Poland
were investigated. The morphological traits as well as the seed morphology and nutrient contents were studied. Substantial
differentiation in some morphological characteristics was noticed. The plants could be assigned to two groups: one group comprising
the lines from the Mediterranean basin (Italy and Spain) and the other group containing the accessions from West-central Europe
(Northern France, Germany and Poland). The grass pea plants produced from the seeds obtained from West-central Europe appeared
to be about 10 cm taller than the Mediterranean accessions and had predominantly white flowers. Their seeds were more than
two times smaller than seeds of the accessions of Italian or Spanish origin. There were not noted any considerable differences
in nutrient contents or antinutritional factors in seeds between these two groups of Lathyrus accessions. A negative correlation between β-ODAP and tannin contents (r = −0.379, P ≤ 0.05) and a positive correlation (r = 0.843, P ≤ 0.01) between a tannin content and flower color intensity were found. A white or crème colour was associated with a low
tannin level in the seeds, while the colourful blooming accessions had higher tannin contents. |
