Abstract

Plant breeding in the first half of the twentieth century which started with the rediscovery of Mendel’s work, mainly involved development of pure-line(s), clones, hybrids, synthetics and composites with higher yield, stability, better quality and resistance to biotic and abiotic stresses. Following the early success, significant contributions were made in the development of semi-dwarf high yielding varieties of wheat by Borlaug and his colleagues at CIMMYT, Mexico, and of rice by Beachell and his colleagues at IRRI, Philippines. Also, high yielding hybrids were developed in maize, sorghum, pearl millet, sunflower, cotton, rice, pigeonpea and in other crops. Efforts are currently also underway to develop hybrids based on genetically engineered male-sterility systems and apomixis. The twentieth century also saw significant developments in mutation breeding, quantitative genetics and other areas relevant to plant breeding, which helped in a better understanding of the genetic architecture of a trait for formulating suitable breeding strategies. Advances in molecular genetics in the last twenty years have opened up altogether new possibilities in analyzing genetic diversity, fingerprinting genotypes, and using molecular marker assisted selection. The last decade of the twentieth century also saw the development of transgenics, the genetically engineered varieties in a number of crop plants for commercial cultivation. This paper takes a journey in the world of plant breeding through the 20th century.
