Krymsk\u00ae 7
<\/span><\/strong><\/span>(cv. Elta) USPP#16,353<\/strong>
<\/span>Krymsk\u00ae 7 is a unique rootstock for sweet cherry, showing similar precocity and vigor to Mahaleb. Cherry trees on Krymsk\u00ae 7 tolerate high temperatures. Compared with Mahaleb, Krymsk\u00ae 7 is more tolerant of soil moisture extremes. Krymsk\u00ae 7 is well suited to varieties needing improved precocity over Colt and Mazzard. Fruit maturity may be advanced by 1 to 3 days relative to Mazzard. Krymsk\u00ae 7 is not sensitive to the pollen spread ILAR <\/span>viruses . It is cold hardy and stress tolerant. Krymsk\u00ae 7 is adapted to a wide range of soil and growing conditions.<\/span><\/p>\n
