Production of aneuploidy gametes by monosomics of avena sativa L.
Abstract
Parental monosomic (2n-1-41 ) derived from three different cultivars of avena saltiva were crossed with another cultivar (sun II) of the same species and their backcross derivatives were compared. On the basis of micronuclei counts od pollen tetrads , it was found that 20- chromosome gametes were produced in disproportionately higher frequency as compared with the normal haploid gametes. Homozygous background results in more deficient gametes.
