Recent results of Czech-American fir hybridization research
Original language description
Fraser fir (Abies fraseri) Christmas tree plantations in North Carolina are infested by root rot caused by Phytophthora cinnamomi. This disease kills almost 100% of Fraser fir material and leaves the soil permanently infested. Control crossings of Mediterranean fir hybrids Abies cilicica x Abies cephalonica with Abies fraseri were performed to ensure possibly resistant hybrid material of desired Christmas tree parameters. Pollen of various clones of A. fraseri was shipped to the Czech Republic by NCSU.Control pollinations were performed in April/May 2010 and 2011 in our hybridization seed orchards. Female strobili were isolated in the period of their highest receptibility. Cones were collected during September. Cones were dried and completely disintegrated. Basic parameters of cones and seeds were assessed for each seed lot. Seed samples of the individual seed lots were X-rayed for assessment of the final share of full seeds. In 2010, the most successful combination CZ2 x NC81 brought
