Patterns of phenotypic variation in wild tetraploid wheat at Ammiad

Morphological, phenological and yield traits were studied in two or more consecutive years in accessions of Triticum turgidum var. dicoccoides derived from permanent sampling points at Ammiad, E Galilee. Variation in the productivity traits, number of tillers, dry weight of the shoot and number of spikes, in particularly, had a very large environmental component, and the environment also modified the interactions among these traits. However, in characters quantifying the width of the flag leaf, the time of appearance of the first awn and spike size, significant differences among subpopulations from different habitats were maintained in most plantings.
