Evaluation and Selection of Parents

Q.

The entire collections of plants/seeds having all diverse alleles for all the genes of a crop is called:

1. Germplasm

2. Herbarium

3. Genome

4. Gene library

Q. During hybridisation, we get a large number of progenies with mixed characters, but we choose only superior progeny by evaluation and selection.

1. True
2. False

Q. Match the following columns and choose the correct option.
$\begin{array}{cc}ColumnI& ColumnII\\ \text{(a) Mutation breeding}& \text{1. Laborious and expensive}\\ & \text{process to obtain gene}\\ & \text{variation}\\ \text{(b) Selection}& \text{2. Hybrid vigour can be}\\ & \text{maintained for several}\\ & \text{generations}\\ \text{(c) Hybridisation}& \text{3. Planting a plant in a new locality from its native place}\\ & \\ \text{(d) Introduction}& \text{4. Oldest breeding method}\\ & \text{5. Quick method to obtain gene variation}\end{array}$

1. $\begin{array}{ccccc}& A& B& C& D\\ \left(a\right)& 5& 4& 1& 2\end{array}$
2. $\begin{array}{ccccc}& A& B& C& D\\ \left(b\right)& 5& 4& 1& 3\end{array}$
3. $\begin{array}{ccccc}& A& B& C& D\\ \left(c\right)& 4& 2& 3& 1\end{array}$
4. $\begin{array}{ccccc}& A& B& C& D\\ \left(d\right)& 1& 2& 4& 5\end{array}$
