  1. Generation followed by the population name, in parenthesis, and the cultivation environment where ‘f’ denotes field-grown plants at El Centro, California; ‘gh’ denotes greenhouse conditions (University of Wisconsin). ζRoot phenotype was either purple (P) or non-purple (NP). βWhen multiple segregation ratios were considered, based on the progenitor phenotype, the χ2 tested is indicated in bold. *P < 0.05.
