Objective Explore the efficient hardwood cutting propagation technology of peach rootstock GF677.Method The effects of different factors on the rooting and seedling rate of peach rootstock GF677''s hardwood cuttings were studied by using GF677''s annual branches as test materials and setting three factors and three levels orthogonal test of cutting substrate， rooting agent and cutting''s diameter.Result The rooting rate and seedling rate of GF677 were the highest， reaching 90.38% and 40.38%， respectively， when the cutting substrate was a mixture of coconut bran and perlite （volume ratio of 1∶2.5）， 10 g/L rooting powder was dipped in the root， and the cutting''s diameter was 1.0~2.5 cm.Conclusion The results of this study optimized the hardwood cutting propagation technology of peach rootstock GF677， and provided a research basis for the promotion and application of resistance rootstock of peach.
