STUDIES ON PRE-SELECTION OF DWARF TYPE APPLE SEEDLINGS BY STARCH GEL ELECTROPHORESIS |
| Authors: | X. Tang, W. Zhang |
| Abstract:
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%. | |
