The characters remain stable in the progeny obtained by
(i) Pure - line selection (II) Hybridization
(III) Mass - selection (IV) Clonal selection

Options

A. I, II
B. I, IV
C. II, III
D. IV only

Answer

To determine which of the given methods leads to stable characters in the progeny, we will analyze each option step by step.

### Step-by-Step Solution:

1. **Pure-Line Selection**:
- Pure-line selection involves selecting a single homozygous line that has been self-fertilized.
- Since the progeny are derived from a single homozygous parent, the genetic traits remain stable and consistent across generations.
- **Conclusion**: Characters remain stable in the progeny.

2. **Hybridization**:
- Hybridization is the process of cross-breeding between genetically dissimilar parents.
- This method introduces genetic variability, which means the traits may not remain stable in the progeny.
- **Conclusion**: Characters do not remain stable in the progeny.

3. **Mass Selection**:
- Mass selection involves selecting a group of desirable plants from a population and mixing their seeds to produce the next generation.
- This method can lead to variability since it combines traits from multiple plants, which may not be genetically identical.
- **Conclusion**: Characters do not remain stable in the progeny.

4. **Clonal Selection**:
- Clonal selection involves producing genetically identical cells or plants from a single parent.
- Since all progeny are clones of the parent, the genetic traits remain stable and unchanged.
- **Conclusion**: Characters remain stable in the progeny.

### Final Answer:
The characters remain stable in the progeny obtained by:
- (i) Pure-line selection
- (IV) Clonal selection
