FLOWER COLOR INHERITANCE IN SALVIA SPLENDENS |
| Authors: | E. Robertson, L. Ewart |
| Abstract:
Nine distinct flower color phenotypes of Salvia splend ens F. Sellow ex Roem. & Shult. were intercrossed in a diallel without reciprocals. Chi-square analysis of F2 and backcross populations indicated that seven genes control inheritance of flower color. The R and L genes control the colors red R-L-, rose rrL-, salmon R-ll and pink rrll. The Int gene had no effect on the R and L genes when dominant, but when recessive with dominant R and LL, it produced rose color. The P gene controls colored P-, versus white pp, flowers. Purple color is produced by the V gene and burgundy color is controlled by the B gene. The E gene dilutes the colors produced by the other loci. The R, L, Int and P genes exhibit complete dominance while the V, B and E genes are incompletely dominant. The R, B and E genes were discovered during the course of this study. | |
