The production of hybrid seeds through male sterility requires
A. Male sterile line, Maintainer line
B. Male fertile line, Maintainer line, Restorer line
C. Male Sterile line, Maintainer line, Restorer line
D. Male sterileline
Answer: Option C
Solution (By Examveda Team)
The production of hybrid seeds through male sterility requires a Male Sterile line, Maintainer line, and Restorer line.Incorporating male sterility into hybrid seed production reduces its cost and ensures high varietal purity.
In a maintainer line (M), its cytoplasm is male fertile (normal) which interacts with a recessive male-sterile nuclear gene to jointly perform male-fertile phenotype.
The restorer line is used to restore the fertility in the hybrid after crossing with the ms A line in the hybrid production plot.
