Abyssnian pea (Lathyrus schaeferi Kosterin pro Pisum abyssinicum A. Br.) – a problematic taxon

Abstract: 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 … Show more

“…Despite numerous studies focused on the classification of Pisum, this long-standing issue remains unresolved, and much confusion about pea domestication persists [49][50][51][52][53] . One point of contention is the taxonomic status of P. abyssinicum, namely, whether to regard it as an independent species or subspecies within P. sativum 54 . In view of its unique morphological characteristics, degree of reproductive isolation and specific distribution areas 51,54,55 , as well as the results of phylogenetic analyses using genomic SNPs, SVs and PAV identified in the pan-genome, we strongly support P. abyssinicum as an undoubtedly separate species distinct from P. fulvum and P. sativum within Pisum (Figs.…”

“…The identifications were based on the modern comparative collection of seeds and fruits of the Ethnobotany laboratory, as well as seed atlases and monographs [22][23][24][25][26][27] and illustrations published in articles presenting the results of archaeobotanical investigations in Syria and neighboring areas [28][29][30][31][32][33]. Particularly useful for legumes were the study on Ahihud (Israel) by Caracuta et al [34], Günes and Ali in Turkey [35] and Arranz et al [36]; on Pisum by Kosterin [37,38]; on Lathyrus consumption in Late Bronze by Mahler-Slasky and Kislev [39]; on Lens seed variability by Punia et al [40]; on Astragalus [41,42]; and, finally, on Vicia by Han et al [43]. For the identification of the remains of the genus Galium (Rubiaceae), we took into account the differences in the surface cell patterns between fruits (mericarps) with intact cover and those of seeds and of fruits lacking the outer part of the cover, following Khalik et al [44] and Jacquat [27].…”

“…3). Finally, several chromosomal rearrangements differed between P. abyssinicum and P. sativum, and these differences made P. abyssinicum nearly cross-incompatible with P. sativum; this largely explained the significant genetic divergence between P. abyssinicum and P. sativum (Rosen, 1944;Lamm & Miravalle, 1959;Ben-Ze'ev & Zohary, 1973;Conicella & Errico, 1990;Kosterin & Bogdanova, 2008;Kosterin, 2017).…”
