First, they may grow cultivars that are high yielding though susceptible to rust. Second, many farmers may grow cultivars with a similar generic basis of resistance. Expected rust losses can be reduced by (a) more diversified genetic background in released wheat cultivars; (b) greater spatial diversity in planted cultivars; or (c) use of a temporally changing fist of cultivars known to be rust resistant, Yield trade-offs associated with these policies illustrate potential fasts of increasing genetic diversity.Collection: CIMMYT Staff Publications Collection
