Abstract

Feulgen and silver-stained karyotypes and meiosis of two triploid viviparous onion forms (Allium cepa var.viviparum), the Croatian “Ljutika” and the Indian “Pran”, were comparatively analyzed. The results of chromosome measurements show that “Ljutika” and “Pran” are karyologically not identical, although significant similarities were found in the morphology of their chromosomes. Five geographically distant clones of “Ljutika” showed good agreement in the number and gross morphology of the chromosomes and in the number and position of NORs and interphase nucleoli. Heterotrivalents were predominant in meiosis of “Ljutika” but a relatively high frequency of higher multivalents together with univalents and bivalents were also observed. The relationship between “Ljutika” and “Pran” and their possible origin are discussed.
