【Abstract】 apple seedlings from 128 combinations of standard type×standard type,standard type×dwarf type,dwarf type×dwarf type,and 2171 different kinds and varieties from 22 species were used for analysing the isozyme.The proportion of seedlings with or without enzyme band 9(E9) in the bark tissues of shoots can be considered as a genetic marker of dwarf type in apple.It is controlled by two pairs of complementary genes.All of the seedlings were pre selected and more than 10 dwarf type,early mature,long keeping lines were obtained.更多还原
