What is the root of any breeding program?

1. Genetic variability

2. Gametic sustainability

3. Germplasm durability

4. Meiotic Anaphase

Which of the following is the tedious task?

1. Collection of variability

2. Cross hybridization

3. Evaluation of parents

4. Selection of parents

Creation of pure line has to be done in plant breeding at which step

1. After collection of germplasm

2. After evaluation of parents

3. After selection of parents

4. After cross hybridization

After the selection process of desired progeny in the plant breeding program, the process of self-pollination is carried out to

1. Reach a state of uniformity

2. Avoid the segregation of characters in the progeny

3. Both 1 and 2

4. Selection of superior progenies

In-plant breeding, the evaluation in research fields is followed by

1. Testing the materials in the research field for three growing seasons

2. Testing the materials in the farmer's field for at least two growing seasons

3. Testing the materials in the farmer's field for at least three growing seasons

4. Testing the materials in advanced research fields for at least two growing seasons
