Solution(By Examveda Team)

Petalloid and gummifer type of male sterility is found in carrots.
A collection of Daucus species and subspecies, as well as alloplasmic carrot lines, were evaluated for expression of male sterility. More than 100 male-sterile plants were identified and their phenotypes and partial genetic background were characterized. Three potentially new cytoplasmic male-sterile systems based on the cytoplasm of Daucus carota (D. c.) gummifer, D. c. maritimus and D. c. gadecaei were selected.
Genetic analyses suggested that a nuclear-cytoplasmic interaction determined the male sterility of the three sources. Clear differentiation between the new sources and carrot cultivars was possible based on the phenotypic and molecular genetic relationships.
