Hybridisation is used to develop new genotypes, evaluate their performance or exploit hybrid vigor.
The above mentioned crop varities bred by hybridisation and selection, for disease resistance to fungi, bacteria and viral diseases.
| Crop | Variety | Resistance to diseases |
| Wheat | Himgiri | Leaf rust |
| Brassica | Pusa swarnim | White rust |
| Cowpea | Pusa Komal | Bacterial blight |
| Okra | Pusa Swani | Vein mosaic disease |
Why is vivipary an undesirable character for annual crop plants ?
It reduces the vigour of plant
The seeds cannot be stored under normal conditions for the next season
The seeds exhibit long dormancy
It adversely affects the fertility of the plant
Assertion: Inbreeding increases homozygosity, thus exposes harmful recessive genes, which are eliminated by selection.
Reason: Continued inbreeding reduces fertility and productivity.
If both assertion and reason are true and reason is the correct explanation of assertion.
If both assertion and reason are true but reason is not the correct explanation of assertion.
If assertion is true but reason is false.
If both assertion and reason are false

Assertion: Somatic hybridisation is a process where protoplasts of two desired plants can be fused to develop improved plants.
Reason: Cross breeding can also induce variability
