Question:
Given below are two statements :
Statement (I) : An effective germplasm collection is the pre-requisite for any successful breeding program.
Statement (II) : Genetic variability is the root of any breeding program.
Given below are two statements :
Statement (I) : An effective germplasm collection is the pre-requisite for any successful breeding program.
Statement (II) : Genetic variability is the root of any breeding program.
Statement (I) : An effective germplasm collection is the pre-requisite for any successful breeding program.
Statement (II) : Genetic variability is the root of any breeding program.
Show Hint
Genetic variability is the raw material of evolution and plant breeding. Germplasm collections are the reservoirs where this genetic variability is stored and preserved for breeders to use.

The Correct Option is A
Solution and Explanation
Step 1: Understanding the Concept:
Plant breeding is the science of changing the genetics of plants to create desired phenotypes.
Every selection-based breeding program relies entirely on the presence of genetic differences within the breeding population.
Step 2: Detailed Explanation:
Let us analyze both statements:
- Statement (I) is true: Germplasm refers to the sum total of all the genes and their alleles present in a crop species and its wild relatives.
An extensive, well-characterized germplasm collection serves as the essential raw material for plant breeders.
Without a diverse germplasm collection, breeders cannot introduce new agronomic traits or adapt crops to environmental stresses, making it a prerequisite for any successful breeding program.
- Statement (II) is true: Genetic variability is the presence of different genetic alleles within a population.
If all plants in a population are genetically identical (zero genetic variability), no genetic gain can be achieved through selection.
Therefore, genetic variability is the foundation and root of any crop improvement program.
Thus, both Statement (I) and Statement (II) are true.
Step 3: Final Answer:
Both Statement (I) and Statement (II) are true.
Plant breeding is the science of changing the genetics of plants to create desired phenotypes.
Every selection-based breeding program relies entirely on the presence of genetic differences within the breeding population.
Step 2: Detailed Explanation:
Let us analyze both statements:
- Statement (I) is true: Germplasm refers to the sum total of all the genes and their alleles present in a crop species and its wild relatives.
An extensive, well-characterized germplasm collection serves as the essential raw material for plant breeders.
Without a diverse germplasm collection, breeders cannot introduce new agronomic traits or adapt crops to environmental stresses, making it a prerequisite for any successful breeding program.
- Statement (II) is true: Genetic variability is the presence of different genetic alleles within a population.
If all plants in a population are genetically identical (zero genetic variability), no genetic gain can be achieved through selection.
Therefore, genetic variability is the foundation and root of any crop improvement program.
Thus, both Statement (I) and Statement (II) are true.
Step 3: Final Answer:
Both Statement (I) and Statement (II) are true.
