The result showed that the best time for sampling was 7 to 14 days after the first bud flowering on the main anthotaxy. The capacity of embryoid production varied significantly in different genotypes. Among them, twelve genotypes yield embryos successfully, which the rate could reach 71%. Genotype 102 was an ideal material for embryoid induction, and the frequency could reach 32.78 embryos per bud. Genotype that with a highest yield produced 546 times as many embryos as that with a lowest yield. The embryoid induction ability of normal bolting genotypes were higher than easy bolting and hard bolting genotypes.
