Popis: The incident of structural heterozygosity is presently noticed for the first time in 9 diploid species, namely, Artemisia annua (n=9), Datura stramonium (n=12), Dicliptera bupleuroides (n=13), Hemigraphis latebrosa (n=12), Leycesteria formosa (n=9), Salvia plebeia (n=8), Senecio nudicaulis (n=5), Sonchus brachyotus (n=9) and Verbena officinalis (n=6, 7). These are heterozygous for chromosomal alternation involving 4-6 chromosomes in reciprocal translocations. All the species show >80% pollen fertility thus indicated the possibility of multivalent formation with alternate disjunction. Almost all the species are involved in some sort of meiotic abnormalities during meiosis I and II. Key words: Multivalent, reciprocal translocations, structural heterozygosity, pollen fertility.
