Show Answer
Answer:
Correct Answer: C
Solution:
[c] Green revolution was possible due to hybridisation.
Increased chlorophyll content has no effect on yield of crops.
Hybrid plants were dwarf because of selection.
Quantitative trait mutations are not involved in hybridisation.
In 1963, ICAR introduced many selections from CIMMYT including those developed by Norman Borlaug using Norm-10 as the source of dwarfing genes (CIMMYT- Centro International de Mejoramiento de Maiz Y Trigo).
