Radiation Interception, Conversion and Partitioning Efficiency in Potato Landraces: How Far Are We from the Optimum?

Crop efficiencies associated with intercepted radiation, conversion into biomass and allocation to edible organs are essential for yield improvement strategies that would enhance geneticproperties to maximize carbon gain without increasing crop inputs. The production of 20 potatolandraces—never stud...
