Can we still grow viable wheat plants in order to survive a nuclear catastrophe?

One of the consequences of a nuclear war is the destruction of the ozone layer. This creates UV stress for plants growing under extreme conditions. Can we still harvest a crop and get viable seeds?This trial was to evaluate the germination and morphology of newly germinated wheat plants-post UV treatments. The plants from which seeds were harvested for this trial were subject to four UV radiation treatments at four different times during their growing season.
