Abstract

Cytological study of a barley mutant produced by EMS treatment showed a high frequency of eccentric or failure of, cell plate formation in the PMC's following meiosis I and/or II. The mutant showed complete male sterility. The behaviour of the chromosomes during meiosis was normal and the equatorial plane was always found to be centrally placed. However, the cell plate did not coincide regularly with the equatorial plane which is an exception to the previous findings.

As a consequence of abnormal cytokinesis sporads containing cells of different sizes and numbers were produced. Failure of cytokinesis resulted in the formation of binucleated and multinucleated cells. The nuclei enclosed in the same cell trended to fuse together and produced polyploid cells. The character was governed by a single recessive gene
