SUMMARY -Karyotypes of four species of South America natives, Lathyrus pubescens, L. macrostachys, L. neroosus, L. crassipes and one cultivated species L. odoratus, are described. All species have 2n = 14 chromosomes. Differences were seen among species in some aspects: in the metacentric, submetacentric and subtelocentric chromosomes numbers, in the numbers and positions of secondary constrictions, in the size of chromosomes and in the total size of complement.

“…However, others have found enough interspecific karyotype differences to allow species characterization (Yamamoto et al 1984, Murray et al 1992, Battistin and Fernández 1994). Such discrepancy was also observed at the infraspecific level, mainly in the widely studied L. odoratus L. and L. sativus L. (Bhattacharjee 1954, Sharma and Datta 1959, Verma and Ohri 1979, Murray et al 1992b. From a karyosystematic point of view, Yamamoto et al (1984) have noted that Old World species could be grouped according to their karyotype morphology and that some of them were coincident with the taxonomic sections proposed by Davis (1970).…”

SummaryThe karyotypes of 21 accessions of Lathyrus L. belonging to 4 sections were investigated. Although all the species have a chromosome number of 2nϭ14, they could be differentiated by their karyotype formula and quantitative parameters of the karyotypes. Phenetic distance showed that in spite of the differences observed among entitied, they can be grouped in clusters that coincide with the taxonomic sections established by Kupicha and with the life cycle of the species. The section Clymenum can be distinguished by the presence of a subtelocentric pair. From an evolutionary point of view, variation in genome size, however, is congruent with morphological variation as well as with the life cycle.

Genetic Variability in Lathyrus spp. as Revealed by Karyotype Analysis

et al. 2009

View full text Add to dashboard Cite

SummaryThe genetic variability based on karyotype formula was studied for 40 accessions of genus Lathyrus. All accessions have 2nϭ14 chromosomes. Karyotype formula has a great uniformity among accessions of each species, suggesting interaspecific stability in Lathyrus species. Our data allowed the differentiation of several accessions among sections Lathyrus, Linearicarpus and Clymenum in number of m chromosome. The variation among section Lathyrus supports that section Lathyrus is not fully constant as has been postulated. Satellites were detected in a pair of chromosome in L. sativus (TUN and AFG). On the otherhand, B-chromosome was detected in L. sativus (USSR, BAN, CAN, and PAK) L. gorgoni (JOR) and L. annus (SYR). This finding may be due to the variation in DNA amount by increase in the non-repetitive sequence. The variation in size of chromosomes of the members of Lathyrus is associated with the evolution in the genus.
