POPULATION CYTOGENETICS IV. VARIABILITY IN SORGHUM HALEPENSE (L.) PERS. FROM HARYANA

Abstracts

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.
