Colt
This cherry rootstocks is resistant to bacterial canker, and is more tolerant of heavy soils than Maheleb. It is drought sensitive, slightly dwarfing, and susceptible to crown gall.
Mahaleb
This cherry seedling rootstock is drought tolerant, resists bacterial canker, and is tolerant of root lesion nematode and crown gall. It is very susceptible to Phytophthora , crown and root rot.
Mazzard
This cherry seedling rootstock is water tolerant, cold hardy, vigorous, and resists root knot nematodes. It is slower bearing than other cherry rootstocks.
Clonal Mahaleb’s Compact 159-5
This cherry rootstock has uniformity of plant material compared with seed-propagated Mahaleb. Survival comparable to standard Mahaleb. Tree size reduction by approximately 15% compared with standards. Suitable for higher density plantings, increased yield efficiency. Low root and trunk sucker production. Precocious fruit flowering and fruit production. Fruit size, yield comparable to or greater than standard. Low doubling, spurring and deep suture production even with smaller tree. Has advanced bloom in some seasons with Bing variety.
Performer 156-5
This cherry rootstock has uniformity of plant material compared with seed-propagated Mahaleb. Survival rate at all test sites, (higher than standard Mahaleb), slightly below Shilo. Low root and trunk sucker production. Precocious, early high yields with Bing variety.
Shilo 155-1
This cherry rootstock has uniformity of plant material compared with seed-propagated Mahaleb. 100% survival at all test sites with low root and trunk sucker production. Full size tree comparable to standard seed-produced Mahaleb, vigorous with fruit size yield comparable or greater than standard. The rootstock showing superior resistance in these stem inoculation and soil-flooding test were propagated vegetatively, then budded with Bing variety and field tested since 1995.
