Cytogenetic Study on Five Species of Genus Anemone L. (Ranunculaceae) from the Western Himalayas, India

抄録

During the present course, population-based meiotic studies were carried out on five species of genus Anemone from selected localities of Himachal Pradesh in the Western Himalayas (India). Varied intraspecific morphotype and B-chromosome were reported in A. obtusiloba. Impaired male meiosis was noted in all populations of A. obtusiloba, A. polyanthes, A. rivularis, A. tetrasepala, and A. vitifolia. These anomalous species were marked with meiotic abnormalities in the form of cytomixis, chromosomal stickiness, unoriented bivalents, formation of laggards and bridges resulting in abnormal microsporogenesis, and production of heterogeneous-sized fertile pollen grains along with reduced pollen fertility.
