In the 1960s, a rice seed, called “Sangryonjong”, was developed in the DPRK.
The seed was instrumental in developing agriculture of the country in those days as it made it possible to overcome cross incompatibility.
It was developed by Kim Sang Ryon (April 24, 1926- June 3, 2005). Still today, the Korean people call him a doctor of rice in admiration. And the State named the seed after him.
After graduation in biology at Kim Il Sung University, he started his career as a researcher of the then national agricultural science institute and was promoted to be the director of the Rice Research Institute under the Academy of Agricultural Science and, in the course of this, he made a great contribution in developing the science of breeding in the country.
He devoted over half a century of his life to the biological research of crops to develop and breed a lot of high-yielding crops suitable to the climatic and soil conditions of the country.
He bred tens of kinds of rice seeds with high yield per hectare and strong resistance to blast and salt and raging wind.
He wrote many books concerning rice cultivation, and presented many scientific essays to the journals at home and abroad.
He also trained many influential scientists. Kim Yong Dok, Ro Song Ik and Paek Kun Su, renowned as masters in the breeding science sector, are his disciples.
Kim Sang Ryon was an academician, professor and doctor, and People’s Scientist.
The State awarded him Kim Il Sung Prize and the title of Labour Hero in recognition of his merits.
His remains are now buried in the Patriotic Martyrs Cemetery.
