Inheritance of pink filament in cotton
1987
Wilson, F.D.
The stamens of a photoperiodic race stock of cotton, Gossyplum hirsutum L., had pink filaments and the petals had a basal wine-colored spot, the latter conditioned by the R2 gene. A cross of this stock to cultivars of upland cotton, which had cream filaments and lacked a petal spot, showed that non-petal spot was epistatic to pink filament. A cross between a line selected for full petal spot and pink filaments and one selected for full petal spot and cream filament showed that pink filament is conditioned by two incompletely dominant gene pairs, tentatively designated Pf1 and Pf2.
