This is an English translation of a paper published in Russian (but with proper Latin formulations at taxonomical novelties to make them validly published) on March 15, 2017 in Vavilov Journal of Genetics and Plant Breeding, Vol. 22 (2): 158-169. The Abyssinian pea (Pisum abyssinicum A. Br.), concerned in this review, is known from Ethiopia and Yemen, where it is cultivated along with the common pea (Pisum sativum L. subsp. sativum). The continuously reproduced notion of its possible spontaneous occurrence in the wild ascends to suppositions made in the XIX century and is not based on any actual data. P. abyssinicum is of practical interest owing to its extra early ripening and resistance to bacterial blight. Morphologically it is very similar to P. sativum but its crossability with it is bad as either seed or pollen parent. Traditionally this reproductive barrier was associated with karyological differences. The Abyssinian pea karyotype is variable as 1-2 reciprocal translocations were reported. At the same time there are accessions not differing from the standard karyotype of P. sativum with respect to reciprocal translocations, yet their crossability with the latter is very low and the pollen fertility of F1 and F2 hybrids is lowered. Data were reported on influence of the region of Linkage Group III, containing a gene known to participate in the conflict of nucleus and plastids in remote crosses of peas, on the pollen fertility of hybrids with abyssinian pea. With their karyological variability, the known accessions of the Abyssinian pea are very close to each other genetically, as they diverged just about 4 000 years ago. The presence of alleles of molecular markers common with Pisum fulvum Sibth. et Smith on the one hand and with P. sativum L. subsp. elatius (Bieb.) Schmalh. on the other hand evidences in favour of an old hypotheses by L.I. Govorov that the Abyssinian pea originated from their spontaneous hybrid. This spontaneous cross may have taken place under cultivation, in Yemen or Afar Depression. A representative of P. sativum subsp. elatius was revealed, the F1 hybrids of which with the Abyssinian pea as a seed parent had fully fertile pollen. P. abyssinicum × P. fulvum crosses provide the best hybrid seed outcome among remote crosses conducted, so that P. abyssinicum can be used as a 'bridge' for gene introgression from P. fulvum to P. sativum. Rather a high level of reproductive isolation of the Abyssinian pea from other representatives of the genus conforms the biological species concept, however the disposition of P. abyssinicum accessions as a small cluster among accessions of P. sativum subsp. elatius on molecular phylogeny reconstructions violates the phylogenetic species concept. Most authors assume the Abyssinian pea as a species, Pisum abyssinicum, some as a subspecies, P. sativum subsp. abyssinicum (A. Br.) Berger. Perhaps it would be most correct to consider it as a hybridogenic species. Because of the recent subsuming of the genus Pisum L. into the genus Lathyrus and with respect to th...

“…elatius, P. abys sinicum, or even P. fulvum (surely a very rare but still possible event). Hedrick et al (1928) as close to P. abyssinicum -a cultivated plant endemic for Yemen and Ethiopia, which is presently considered a product of hybridisation between P. sativum and P. fulvum (Vershinin et al, 2003;Jing et al, 2010;Kosterin, 2017). Of external characters, they share small habitus, small pale flowers, absence of any pattern on the seed testa (so in most representatives of P. abyssinicum) and of the pod neoplasia.…”

“…For the sake of practical convenience, in this work I proceed considering Pisum as a genus, although a recent molecular phylogenetic analysis of the tribe Fabea (Schaefer et al, 2012) suggested to cancel the genus Pisum and subsume it, as a section, to the genus Lathyrus L. (Coulot, Rabaute, 2016;Kosterin, 2017). Since I do not support a subspecific rank of the taxa considered, treatment of the common pea in the genus Lathyrus (under the name Lathyrus oleraceus Lamarck) would not demand new combinations.…”

“…elatius, which occurred in the western half region of the Fertile Crescent [13] and then a small sample was introduced to north-eastern Africa, where it evolved into the modern P. abyssinicum [14]. The very low genetic diversity in the Abyssinian pea suggests that the taxon has recently experienced a severe bottleneck or is a relatively young taxon [10] and the hybridization event has most likely occurred about 4000 years bp [15].The Pisum genus is very diverse, showing the gamut of relatedness that reflect taxonomic identifiers, eco-geography and breeding gene pools [8,12,16,17]. Several phenotypic classification studies on pea germplasm are based on agronomical characteristics and morphological descriptors [18][19][20][21], which are unreliable for the evaluation of pea genetic resources and the identification of different cultivars in the Fabaceae family [22], especially considering the environmental effects on the expression of the genotype.…”

Pea (P. sativum L.), one of the most important legume crops worldwide, has been traditionally cultivated in Lesser Cyclades since ancient times. The commonly known traditional pea cultivar, 'Katsouni', is endemic to the islands of Amorgos and Schinoussa and is of great local economic importance. Despite the widespread cultivation of 'Katsouni' in both islands, it is still unknown whether the current Schinoussa and Amorgos pea populations are distinct landraces, and if they have common evolutionary origin. To assist conservation and breeding of the pea crop, the genetic diversity and phylogenetic relationships of 39 pea samples from Amorgos and 86 from Schinoussa were studied using DNA barcoding and ISSR marker analyses. The results indicate that both populations are different landraces with distinct geographical distribution and are more closely related to P. sativum subsp. elatius than the P. abyssinicum and P. fulvum species. Further characterization of the 'Katsouni' landraces for functional polymorphisms regarding pathogen resistance, revealed susceptibility to the powdery mildew (Erysiphe pisi DC.). This work represents the first investigation on the genetic diversity and population structure of the 'Katsouni' cultivar. Exploiting the local genetic diversity of traditional landraces is fundamental for conservation practices and crop improvement through breeding strategies. Pea (P. sativum L.) is among the most important legume crops, such as chickpea (Cicer arietinum L.), lentil and faba bean (Vicia faba L.), in temperate climates and has a wide geographical distribution, with field pea being specifically adapted to a wide range of climates and altitudes. The Pisum species are of high commercial importance and are cultivated worldwide for dry and fresh consumption. According to the International Legume Database (ILDIS) and to the classification of Maxted and Ambrose (2001) [7], the Pisum genus includes three species: i) Pisum abyssinicum, ii) Pisum fulvum and iii) Pisum sativum L., which further includes the wild pea, Pisum sativum subsp. elatius (M. Bieb. Asch. & Graebn) and the domesticated pea, Pisum sativum subsp. sativum.Phylogenetic analyses of various pea taxa with molecular markers indicate that hybridization between wild peas is not an extensive phenomenon [8]. The recently annotated pea genome sequence and the resequencing of data from 42 wild, landrace and cultivar Pisum genotypes, provided further insights into legume genome evolution [9]. It has been suggested that the common ancestor of the Pisum species was probably cytogenetically similar to P. sativum subsp. elatius, which evolved across the Mediterranean and Middle East [8] and gave rise to P. sativum subsp. sativum and P. fulvum in the northern Middle East. Regarding P. abyssinicum, two main hypotheses exist; it is considered the result of a domestication event from a southern P. sativum subsp. elatius ancestor [10] followed by a migration to Abyssinia, possibly through ancient human trading routes [11], indicating at least two domesticati...
