'Stock 6' is a haploid inducer line of:
Show Hint
Haploid induction:
- Stock 6: Maize haploid inducer line.
- Used to produce doubled haploids (DH).
- Accelerates breeding by producing homozygous lines.
- Stock 6: Maize haploid inducer line.
- Used to produce doubled haploids (DH).
- Accelerates breeding by producing homozygous lines.

- Wheat
- Maize
- Rice
- Sorghum
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Understanding the Question:
This question tests knowledge of haploid inducer lines in crop plants.
Step 2: Detailed Explanation:
'Stock 6' is a haploid inducer line of maize (B).
It is used in maize breeding to produce haploids (doubled haploids).
Haploid induction involves crossing the inducer line with a donor line to produce haploid progeny.
Other crops:
- Wheat (A): Haploid induction is done through anther culture or chromosome elimination.
- Rice (C): Haploid induction through anther culture.
- Sorghum (D): Haploid induction is less common.
Thus, 'Stock 6' is a haploid inducer line of maize.
Step 3: Final Answer:
Thus, 'Stock 6' is a haploid inducer line of maize, which corresponds to option (B).
