India’s wheat yield revolution in the 1960s was possible primarily due to
-
- hybrid seeds
- increased chlorophyll content
- mutations resulting in plant height reduction
- quantitative trait mutations
- hybrid seeds
Correct Option: C
Green revolution was possible due to hybridization. Increased chlorophyll extent has no effect on yield of crops. Hybrid plants were dwarf because of selection. Quantitative trait mutations are not involved in hybridization. In 1963, ICAR introduced many selections from CIMMYT include those developed by Norman Borlaug using Norin-10 as the source of dwarfing genes (CIMMYT-Centro International de Mejoramiento de Maiz Y Trigo).
