Discuss the role of hybridisation in crop improvement.

Hybridization is a method of crossing two dissimilar varieties to get desirable characters in the off-springs. Hybridization improves the crop in following attributes

High yield: Hybridization helps to improve crop yield

Pest resistance: Crop can obtain pest resistance by incorporating pest resistance genes. Ex: BT Cotton Draught resistance: Plants obtain draught resistant genes from draught resistant varieties.

Disease resistance: Plants can be immune to certain disease against which genes are incorporated.
