A hypothesis that cherry rootstocks grown under optimal nutrient conditions are affected less by Pratylenchus penetrans infection than those grown under deficient nutrient conditions was tested by growing four Prunus avium L. rootstocks ('Mazzard', 'Mahaleb', 'GI148-1', and 'GI148-8') at a soil pH of 7.0 over a period of 3 months under greenhouse conditions (25 ñ 2 degrees C). Pratylenchus pene...

Abstract The pollination of self-incompatible diploid sweet cherry is determined by the S-locus alleles. We resolved S-alleles 50 cultivars grown in Estonia and their incompatibility groups, which were previously unknown for most tested cultivars. used consensus primers SI-19/20, SI-31/32, PaConsI, PaConsII followed allele-specific sequencing to identify S-genotypes. Surprisingly, 48% (24/50) c...
