Abstract: | Summary In order to test Pandey's hypothesis that peroxidase isoenzymes determine S-gene specificity in Nicotiana alata, peroxidase isoenzymes in styles and pollen from various plants of an inbred- and a cross progeny were compared by means of starch gel electrophoresis and electrofocusing.No relation between the S-genotype and the peroxidase isoenzyme patterns of pollen or of styles could be established. The differences between the isoenzyme patterns of different S-genotypes were ascribed to differences in the genetic background of various plants that had the same S-genotype. |
