GENETIC MALE STERILITY IN SALVIA SPLENDENS AND ITS USE IN PRODUCTION OF F1 HYBRIDS. |
| Author: | L.C. Ewart |
| Abstract:
In a research program to improve and develop better line bred Salvia splendens cultivars, two different genetic male sterility systems have been found. The first system was found in a single male sterile plant of the cultivar Harbinger in 1962. This system has been found to be inhereted as a single dominant gene maintained in a heterozygous condition. The second system developed from a single male sterile plant found in the cultivar Bonfire Early Strain in 1967. It was found to be inherited as a single recessive gene. Using the dominant male sterile system for seed production, the first Fl-hybrid salvia cultivar Hot Pants, was introduced for sale in 1972 followed by Torch in 1975 and in 1976 by Trail Blazer and Tallyho. | |
