Improved potato variety ‘Qingshu 9’ a success story in China and beyond

In their efforts to improve the food security and livelihoods of farmers around the world, potato breeders at the International Potato Center (CIP) strive to develop marketable, resilient varieties with resistance to viruses and late blight that can be grown in an array of environments. An excellent example of the potential of such a potato is CIP variety No. 392797.22, a high-yielding clone that can be found in fields all over China and is grown in several other countries. The Chinese government is promoting potato production to improve food security, and CIP 392797.22 has proven to be an excellent option for the country’s farmers.

Originally developed in Peru in the 1990s, the variety was selected from a cross of CIP No. 387521.3 and ‘Aphrodite’, from CIP’s lowland tropics virus resistant population. It was field tested in Peru’s lowlands and mountains and was first released to farmers in 1998 by the National University San Luis Gonzaga, Ica under the name ‘UNICA’. Field trials showed that it has a stable, high yield in varied environments, is resistant to viruses, and tolerates drought. It also produces quality potatoes with red skin and yellow flesh that are good for fresh consumption and have the qualities needed for French fry production.
