Question

Higher yield and disease resistance are the characteristics a farmer desires in any crop. Scientists develop such varieties by hybridisation of two different crops. Such a hybridisation could be :

• A. Inter-varietal type
• B. Inter-specific type
• C. Inter-generic type
• D. In-vivo type

Answer 1

Answer: (A), (B), (C)

The correct options are
A Inter-varietal type
B Inter-specific type
C Inter-generic type

The traditional method to develop hybrid varieties for higher yield and disease resistance is called breeding. It is also known as hybridisation. Here, two crops used for hybridisation could belong to :
1. different varieties but same species (inter-varietal),
2. different species but same genus (inter-specific)
3. different genera altogether (inter-generic).
