Krw. Hammett et al., NEW INTERSPECIFIC HYBRIDS IN LATHYRUS (LEGUMINOSAE) - LATHYRUS-ANNUUSX LATHYRUS-HIEROSOLYMITANUS, Biological Journal of the Linnean Society, 122(2), 1996, pp. 89-101
Experimental hybridization, cytogenetic observation, flower pigment an
alyses and scanning electron microscope observations of seed coat feat
ures were used to investigate the relationship between L. annuus L. an
d L. hierosolymitanus Boiss. Pod width, seed size, shape and surface o
rnamentation proved to be good diagnostic criteria for distinguishing
the two taxa. Hybridization between various accessions of the two spec
ies revealed variation both between and within accessions. Enhanced an
thocyanin levels were detected in the standard petals of the reciproca
l hybrids made between two specific accessions of L. annuus and L. hie
rosolymitanus. The results of the investigations support the retention
of L. annuus and L. hierosolymitanus as separate species.
