Hari Krishan Jain (28 May 1930 - 8 April 2019) was an Indian cytogeneticist and plant breeder, known for his contributions to the field of genetic recombination and the control of interchromosome level.
[8] Subsequently, he pursued his doctoral studies at the Aberystwyth campus of the University College of Wales, on a Science Research Scholarship of the Royal Commission, London to secure his PhD and returned to India to start his career as a cytologist at IARI in 1956.
Jain's early researches on Lilium, a genus of herbaceous plants, and its meiotic cell division revealed the correlation between the chromosome condensation and nucleolar synthesis.
He is credited with developing the concept of national multilineal complex of varieties and the proposal of the multiple and inter-cropping patterns, later popularized by the Indian Agricultural Research Institute.
[11] He authored five books[12] which included Plant Breeding: Mendelian to Molecular Approaches[13] Genetics: Principles, Concepts and Implications,[14] and Green Revolution: History, Impact and Future[15] and several articles which document the body of his work.
[16] Jain has served as a member of the Scientific Advisory Committee (SAC-C) to the Government of India (1982–83) and the Uttar Pradesh State Planning Commission (1978–80).
