Consider the given two statements:
I: | As a part of maintaining the germplasm collection, the stored seeds are grown periodically in the field to obtain fresh seeds. |
II: | The germplasm collections are usually maintained at a low temperature in the form of seeds. |
1. Both I and II are correct and II explains I.
2. Both I and II are correct but II does not explain I.
3. I is correct and II is incorrect.
4. Both I and II are incorrect.
Most plant introductions in a country like India are:
1. | grown directly by the farm |
2. | ornamental plants introduced for their aesthetic values |
3. | used as parents in hybridization in breeding programs |
4. | invasive species that cause harm to the ecosystem |
The selection in cross-pollinated crops ultimately aims at:
1. | selecting the most desirable pureline. |
2. | increasing the frequency of superior genotypes without reducing heterozygosity. |
3. | removing all true breeding varieties from the germplasm and hybridizing only heterozygous varieties. |
4. | converting purelines into apomicts to prevent segregation of desired traits. |
Practically all hybrids of poultry and swine are produced by:
1. crossing inbred stocks
2. introduction of exotic breeds
3. crossing genetically similar parents
4. mutation breeding
