Question

Choose the correct statements:
A. Nobilisation is related to sugarcane
B. ICPH8 was 1st hybrid of cotton
C. Marcotting is process of isolating canes for crossing purpose
D. 'D' genome of wheat is Triticum monococcum
E. Primary centre of origin of pigeonpea is Hindustan centre.

• A. A, B, C, D only
• B. A, B, C, D, E only
• C. A, B, C, E only
• D. A, C, E only

Hint:

Remember: H-4 = First cotton hybrid
ICPH-8 = First pigeonpea hybrid

Answer 1

The Correct Option is D

Concept: This question includes important facts related to crop breeding, crop origin, and genetics.

Step 1: Evaluate statements related to sugarcane and pigeonpea.
Nobilisation refers to the improvement of sugarcane varieties through interspecific hybridization. Marcotting is a technique used in sugarcane breeding to isolate canes for crossing purposes. Pigeonpea originated in the Hindustan centre of origin. Thus, statements A, C, and E are correct.

Step 2: Analyze the incorrect statements.
ICPH-8 was the first hybrid of pigeonpea, not cotton. The first cotton hybrid in India was H-4. The D genome of wheat originated from Aegilops tauschii, not Triticum monococcum. Therefore, statements B and D are incorrect.
