| Abstract:
Cox's Orange Pippin and Bramley's Seedling apple trees raised on MM.106 rootstocks, using budwood from trees previously micropropagated for a short period, grew more vigorously in the nursery and after planting in the orchard, than trees raised by conventional techniques from budwood collected from mother trees. Cox trees raised from budwood derived from several post-micropropagation selections exhibited differences in floral precocity, fruit set and vigour over the early stages of orchard life. Treatment of Cox, or Bramley, vegetative buds during micropropagation with ethyl methane sulphonate (EMS) also produced selections exhibiting differences in vigour, floral precocity and fruit set. | |
