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.
