Abstract

Three different chromosome numbers, 2n =10, 2n =12 and 2n = 14 have been found in the wild populations of Vicia sativa of Israel. In both the 2n = 10 and 2n = 12 forms two different karyotypes were present but the 2n = 14 type apparently has a stable karyotype. The 2n = 10 types of V. sativa grow mainly in man-made habitats while the 2n =12 and 2n = 14 types are usually confined to primary habitats. Occasionally, plants having different chromosome numbers or karyotypes form mixed populations. No definite connection between chromosome types and taxonomic units could be established within V. sativa but it is worth emphasising that only var. amphicarpa had 2n = 14. This vetch is unique also in bearing subterraneous pods and its chromosome complement is the shortest in the entire aggregate. These facts have been taken as an indication that var. amphicarpa is an advanced form in the V. sativa aneuploid series.
