Stock and scion studies. XHI. Some new clonal pear rootstocks

Abstract

In a stock-scion trial in south-eastern Queensland 12-year-old Williams' Bon Chretien trees propagated on several Australian rootstocks selected for their ability to root freely in layer or stool beds and designated "T", and on East Malling D3 clonal stock, made better growth and produced heavier crops than trees on Kieffer's seedling. Williams' Bon Chretien propagated on its own rootstock gave a poor performance. The most promising rootstock was T7. It can be propagated in layer beds and confers vigour and earliness of bearing on the scion variety.
