Abstract

Meiotic studies were carried out on six populations of Sorghum halepense (L.) Pers.  from various localities of Haryana. All populations are tetraploid 2n=40 with x=10. The more common meiotic abnormalities are the presence of laggards at anaphase and telophase (suspected to be B-chromosomes) chromosome stickiness and high pollen sterility.  Many bivalents show early disjunction at Anaphase-I  and  in few PMCs loose association of bivalents has been observed.

Keywords: Sorghum halepense, Chromosome stickiness, chromosomal variables in natural populations, laggards and B chromosomes.
