PEACH RESISTANCE TO APHID VECTORS OF PLUM POX VIRUS |
| Authors: | G. MASSONIÉ, P. MAISON |
| Abstract:
Two varieties of Prunus persica L. Batsch, a clone and seedlings, are highly resistant to Myzus persicae Sulz. and Myzus varians Davids. Resistance is linked with a necrosis of tissues punctured by the insects. The susceptible variety Jungermann 3197 grafted on the resistant varieties remains susceptible. The infection of the seedlings by the plum pox virus does not involve the loss of the resistance. The seedlings of the varieties 2605 and 2678 are most resistant to inoculation of plum pox virus by M. persicae Sulz. than those of GF 305. The results are discussed in relation with their possible interest for the control of the plum pox virus. | |
