Q- (a) What do you understand by genetically modified crops?
(b) What are the desired agronomic characters for fodder and cereal crops?
(c) What are the advantages of improved varieties of hybridisation?
Answer- (a) Genetically modified crops are a kind of crops that are genetically modified or improved to increase their disease resisting power as well as their production quantity and quality. In it the DNAS of crops are modified by genetic engineering methods to add desired agronomic characters in such a crop.
(b) Some of the main desired agronomic characters for fodder and cereal crops are as follows:
1. Higher yield giving.
2. High resisting power from pests as well as diseases.
3. More adaptability.
4. More responsive to maturity.
5. Early maturing capability.
(c) Hybridisation is the process of crossing of plants of two different varieties to make a modified crop with dominant characters of both plants.
There are several advantages of hybridization. Some of the main advantages of hybridization are as follows:
1. The improved variety had both dominant characters of parent plant.
2. Improvement in the fertility of the hybrid plants produced.
3. The hybrid plants formed are more successful as compared to normal plants.
