Evaluation location: Wisconsin, United States
METHOD: Visual Examination. CONDITIONS: Greenhouse. METHOD NARR: Approximately 500 seeds were sown into 32 x 48 cm plastic flats from 120 populations of adg. Seedlings were grown for about six weeks in the greenhouse, after which time the dwarf phenotypes were clearly distinguishable. Dwarf and total numbers of seedlings were counted for each population. RESULTS NARR: There were dwarfs detected in fourteen of the 120 populations. Ten of the eleven populations from Mexico had dwarfs. The highest frequency (28%) of dwarfs came from a population from Colombia (PI 243364).
