Krymsk\u00ae 6<\/span><\/strong><\/span><\/p>\n

(cv. LC 52) USPP#16,114 <\/span><\/strong><\/p>\n

Krymsk\u00ae 6 is a promising sweet cherry rootstock having more precocity than Mazzard or Colt, yet not as precocious as the Gisela\u00ae series. \u00a0Krymsk\u00ae 6 has more precocity and about 10% less vigor than Krymsk\u00ae 5. \u00a0Krymsk\u00ae 6 has tolerance to stress conditions, such as high temperatures and low soil moisture. \u00a0Krymsk\u00ae 6 is well suited to varieties needing improved precocity. \u00a0Fruit maturity may be advanced by 1 to 3 days relative to Mazzard. \u00a0Krymsk\u00ae 6 is sensitive to the pollen spread ILAR viruses and can produce many suckers in heavy soils. \u00a0<\/span><\/p>\n<\/div>\n<\/div><\/div><\/div><\/div>

DISEASE PROBLEMS--OTHER:<\/strong> <\/span>Very sensitive to PNRS and PDV viruses. <\/span>
ASPHYXIA TOLERANCE:<\/strong> <\/span>More experience is needed. <\/span>
DROUGHT TOLERANCE:<\/strong> <\/span>More tolerant of low soil moisture and <\/span>high temperature stress than Gisela\u00ae rootstocks.<\/span>
