Expert Answer:

Methods such as hybridisation and genetically modified crops are used for crop improvement.
 
Hybridisation- It is the technique of crossing between two genetically dissimilar plants to produce a plant of a new variety. The variety produced by using this technique is called a hybrid. There are rwo types of hybridisation- Inter-varietal cross-breeding and Inter-specific cross-breeding
 
Genetically modified crops- 
  • A gene responsible for desirable characters is transferred from one crop variety to another crop variety. The crop into which the gene is introduced to obtain the desired result is called genetically modified crop (GMO) or transgenic plants.
