Over the last 20 years stone fruit rootstock development has begun shifting from seedling to clonal types, many of interspecific origin. Publicly funded breeding programs have produced most of these rootstocks due to the time, cost, and risk associated with their development; however, private industry is emerging as a significant contributor of many of the newer rootstocks. Particularly noteworthy among recent releases has been the incorporation of resistance to soilborne diseases, nematodes, waterlogging and vigor control, the last most notably in recent cherry rootstocks. Nevertheless, despite the remarkable progress in the development of clonal stocks, seedling rootstocks still dominate most stone fruit industries around the world, if only because of their relatively low cost, ease of propagation, and proven utility. Many opportunities and challenges remain to be addressed in the areas of disease and insect resistance, adaptation to biotic and abiotic stresses, graft compatibility, and rootstock influence on scion performance and fruit quality. Biotechnology is beginning to show potential in accelerating rootstock development. With the development of markers to assist selection for difficult to evaluate traits, new rootstocks with resistance to multiple diseases are feasible. Future prospects for breeding are presented.

Peach seedling rootstocks [Prunus persica (L.) Batsch] have been and continue to be the most important roostocks used for peaches in North America. In the North Central Region of the United States, Simons and Carlson (21) surveyed commercial nurseries in 1966 and 1967 and reported that 97.7% of the peaches were propagated on peach seedling understock. The principal seedling rootstock cultivars were ‘Lovell’, ‘Halford’, ‘Red Leaf and ‘Suncling’, accounting for 95.8% of the propagated trees. The remaining 2.3% of the trees were propagated on P. armeniaca L., P. tomentosa Thunb., P. besseyi Bailey, P. hortulana Bailey, and P. insititia L. cv. St. Julian A. Of these, 1.2% of the trees were on P. besseyi which was used for its dwarfing ability.

“…Various sources of resistance to Armillaria species have been identified [76][77][78][79][80][81][82], and some progress has been made in the development of rootstocks with resistance to Armillaria mellea. 'Ishtara' and 'Myran', both complex plum × peach hybrids, reportedly are significantly more resistant to A. mellea than are peach seedlings [83,84]. Unfortunately, this resistance does not appear to extend to A. tabescens, important species [85].…”

“…Several species of Phytophthora have been demonstrated to be pathogenic on Prunus. Screening methodologies have been developed and some progress made in identifying useful differences in germplasm [83,84,[86][87][88][89][90][91][92][93][94]. Screening of Phytophthora resistant or tolerant Prunus mahaleb rootstocks for Cherries is currently underway at University of California-Davis (T. DeJong, pers.…”

Rootstocks play an essential role to determining orchard performance of fruit trees. Pyrus communis and Cydonia oblonga are widely used rootstocks for European pear cultivars. The lack of rootstocks adapted to different soil conditions and different grafted cultivars is widely acknowledged in pear culture. Cydonia rootstocks (clonal) and Pyrus rootstocks (seedling or clonal) have their advantages and disadvantages. Selecting the right combination of the rootstock and cultivar is important for optimizing fruit quality parameters. Dwarfing is an important agricultural trait for intensive cultivation and effective orchard management in modern fruit orchards. Commercial citrus production relies on grafting with rootstocks that reduce tree vigour to control plant height. Citrus growers all over the world have been attracted to dwarfing trees because of their potential for higher planting density, increased productivity, easy harvest, pruning, and efficient spraying. Dwarfing rootstocks can be used to achieve high density. Citrus rootstocks with dwarfing potential have been investigated regarding physiological aspects, hormonal communication, mineral uptake capacity, and horticultural performance. This study lays the foundation for future research into the genetic and molecular mechanisms underlying citrus dwarfing. Many of the rootstocks now available to growers of apples, pears, peaches, nectarines, apricots, cherries and plums are listed and described briefly. Future rootstock needs for these and other crops are anticipated. Alternatives to rootstocks are considered, in particular the opportunities for scion cultivar improvement which may be offered by the developing techniques of molecular biology. Finally, the need for a better understanding of the physiology of the effects of rootstock on scion growth and cropping is emphasized.
