Genetic Determinism of Xanthomonas arboricola pv. pruni (Xap) Resistance, Fruit Quality, and Phenological Traits in Peach and Incorporation of Marker-Assisted Selection (MAS) in the University of Arkansas Peach and Nectarine Breeding Program
… acidity and soluble solid content (G7Flav)], and phenological traits [maturity date (G4mat), fruit type (G), and flesh color (Y)] across four RosBREED peach breeding programs. First, previously identified QTLs were further investigated and 32 SNPs were grouped into haplotypes and validated for …

Latitudinal Gradient Facilitates Adaptive Population Differentiation of Campanulastrum americanum (American Bellflower)
… and southern populations. Both reproductive and phenological traits of plants of southern origin were differentiated from plants of northern origins and under selection. There was also significant selection towards earlier flowering initiation. Earlier flowering, along with faster bolting rate …

Partitioning of multivariate phenotypes using regression trees reveals complex patterns of adaptation to climate across the range of black cottonwood (Populus trichocarpa)
… of multiple physiological, morphological, and phenological traits. Latitudinal clines for the relevant component traits are frequently observed for species that have a north-south distribution, but these relationships do not account for climatic variation within a given latitudinal band, which …

Sugar maple (Acer saccharum Marsh.) provenances differ with climate of origin in survival, growth, and traits along a climate gradient: implications for the species' distribution under climate change
… and intraspecific variation in growth and traits. Changing climate and species composition in plant communities lends urgency to the need to better define the factors determining species’ distributions. This research seeks to determine the effects of temperature and neighbors on sugar maple …

GENETIC AND QUANTITATIVE VARIATION IN WILD SOYBEAN (GLYCINE SOJA) POPULATIONS
… consists of morphological, agronomic, and phenological traits. These 12 seed accessions are significantly different from one another in most of the quantitative traits measured. The principal component analysis shows about 60% of the phenological variation and about 43% of the agronomic …

Dissecting the genetic, physiological and metabolic mechanisms of grapevine resilience to heat stress
… progeny (around 120 genotypes) was evaluated for phenological traits affected by changing temperatures, in particular bud burst, flowering and véraison, while physiological response to heat stress was assessed in various hot summer days by measuring chlorophyll fluorescence kinetics and stomatal …
