Abstract

In this research, meiotic CHROMOSOME NUMBER and the behavior of four populations of Astragalus anserinifoliusBoiss. of ASTRAGALUS SECT. MALACOTHRIX were studied. All wild populations were diploid and showed 2n=2x=16 CHROMOSOME NUMBER, consistent with the proposed base number of x=8 from IPCN. Although all taxa displayed regular bivalent pairing and chromosome segregation at meiosis, some MEIOTIC ABNORMALITIES included varied degrees of fragmented and sticky chromosomes in metaphase I, polynucleate and a variable number of laggards, forwarded chromosomes and bridges in anaphase I/telophase I, asynchronous nucleus and precocious chromosome migration in metaphase II and laggards, bridges and cytomixis in anaphase II/telophase II were observed.
