in which the brown pigmentation was substituted for yellow. We performed test crosses to determine the genotypes of the rare phenotypes. A cross between a solid yellow flower phenotype and a red flower phenotype resulted in an F 1 plant with dark

combined with a fungus with a long latent period, where the necessary test crosses and other genetic studies are typically not economically feasible. Deciphering the underlying mechanics of resistance will require the screening of a much wider diversity of

seedlings were taken for measurement of leaf dry mass and leaf area, from which the leaf mass per area (LMA) was calculated. The significance of differences between treatment means was determined by Student's t test. Cross-sections of cotyledon in each

C. virginicus and C. pygmaeus accessions were available for sampling and used to test cross-amplification of C. retusus -derived SSRs. A broader sampling, encompassing a greater range of C. virginicus in eastern North America and larger

Fruit set assessment is currently the most commonly used method to test cross-compatibility among olive ( Olea europaea L.) cultivars, thus identifying the best pollenizers ( Androulakis and Loupassaki, 1990 ; Camposeo et al., 2012 ; Cuevas et al
