What was the role of plant breeding in green revolution?

plant breeding played a crucial role during the green revolution  

Explanation:

Plant breeding can be defined as the methodologies used to improve plant phenotypic traits. The methodologies for plant breeding include, among others, making crosses, setting breeding objectives, genetic engineering techniques, selection of progeny, etc. Moreover, the Green Revolution is a period occurring between 1950 and 1960 in which high-yield varieties were developed, specifically in rice and wheat. During this period, high yielding semi-dwarf varieties of rice and wheat arising from the cross between dwarf plants and normal varieties were developed. These high yield crops were resistant to lodging. The combination of these new varieties, fertilizers and new techniques of harvesting drastically improved crop yields, thus reducing hunger in Third World countries.
