(i) Hybridisation is crossing of two or more types of plants for bringing their traits together in progeny.
(ii) Semi-dwarf rice varieties were derived from IR-8 and Taichung Native - 1.
(iii) Hybrid breeding have led to the development of several high yielding varieties resistant to water stress.

• A. (i) - F, (ii) - T, (iii) - T
• B. (i) - T, (ii) - T, (iii) - F
• C. (i) - F, (ii) - T, (iii) - F
• D. (i) - T, (ii) - T, (iii) - T

Answer 1

The correct option is D (i) - T, (ii) - T, (iii) - T

All the statements given above are true.

• Hybridisation is crossing of two or more types of plants for bringing their traits together in progeny. It is the process by which progeny has the desirable features of both parents. So, the given statement is true.
  
• Semi-dwarf rice varieties were derived from IR-8 and Taichung Native - 1. These were introduced in 1966. So, the given statement is true.
  
• Hybrid breeding have led to the development of several high yielding varieties resistant to water stress. For example; hybrid maize, jowar and bajra have been successfully developed in India which are resistant to water stress. So, the given statement is true.
  

So, the correct option is 'Option D' .
