Solution

The correct option is B Statements 1 and 2 are correct.
Hybridisation refers to crossing between genetically different plants. This is done to incorporate desirable characters into the crop variety. There are three types of hybridisation:
Intervarietal hybridisation: It is a cross which is carried over between two varieties of plants.
Interspecific hybridisation: It is a cross which is carried over between two individual plants belonging to different genera of the same family.
Intergeneric hybridisation: It is a cross between two different plants of the same genus.
