Inheritance of photoperiod-induced flowering in three photoperiodic lines of Aeschynomene americana L.

Induction of flowering by photoperiod was studied in the parental, F1, F2, and reciprocal backcross generations of crosses between three photoperiod-responsive Aeschynomene americana L. lines. Generation means appeared additive. Analysis with Mather and Jinks' scaling tests showed little or no epistasis and indicated that an additive-dominance model was adequate. Partitioning components of variation revealed that nearly all variation was additive genetic with dominance and environmental variation negligible. An additive genetic model with two loci, each with two alleles and all alleles having equal net effect, was tested using Power's partitioning method. Results demonstrated that the model fit the data and that there is a major additive genetic system controlling flowering in these crosses, with minor genetic and environmental influences present. Selection for flowering at a desired day length should be feasible.
