STUDIES ON PRE-SELECTION OF DWARF TYPE APPLE SEEDLINGS BY STARCH GEL ELECTROPHORESIS

X. Tang, W. Zhang
The peroxidase isozyme patterns of apple seedlings from 18 crosses were analysed by starch gel electrophoresis. The zymograms of 223 mature plants of 7 crosses were compared with those of their cuttings, and it was found that there is the same zymogram in both mature plants and cuttings. The zymograms of the remaining 9 crosses were also analysed in different years and in different locations. In addition, 64 plants of 2 crosses were systematically observed and analysed. No change was found in the separation ratio of E9 for the 9 crosses in different years and at different locations. Thus, it is confirmed that E9 of peroxidase isozyme can be used as an index for pre-selecting 2–3 month apple seedlings with accuracy of 85%.
