THE GENETICS OF FLOWERING TIME IN RAPHANUS SATIVUS L. III. EARLY X LATE CROSSES, F, AND F2GENERATIONS
AHSAN A. VAHIDY[1] AND RICHARD W. HARTMANN
Abstract
Crossing experiments between early flowering and
late flowering lines were conducted in the green-
house. For this purpose, 10
Early and 10 Late plants were divided into two sets
(each set consisting of 5
Early and 5 Late plants). The crosses were made
between Early and Late
plants in all the possible combinations (including
reciprocals) within each set.
No significant differences between the crosses and their reciprocals were found for the time of flowering. The data of both the F, and
F2 plantings were adjusted by comparing with check plants to make the data of these plantings comparable to that of the original
parental planting. Frequency distributions of the Fj and
F2 showed no dominance for the time of flowering and indicated that there probably
