Abstract:
Parental monosomics (2n-1=4) derived from the cultivars Garry (WM 2-1) from Canada and Borreck (GM 1-1) from West Germany, their monosomic F1 hybrids and BC- BC4 to Sun II were used to study the transmission of deficient gametes. The frequency for functional 20-chromosome male gametes was lower in the homozygous than heterozygous monosomics. The 40-41- and 42 chromosome progenies in selfed monosomic individuals depend upon the proportion of deficient (2n-1) but functional male gametes. The correlation between the proportion of 20-chromosome gametes produced and the proportion that function is significant (r,0.86).
