## In detail

The florets at the ear tip are the last to produce silks, so they are the first to suffer when heat, drought or nutrient shortage hits during flowering. Ears with bare tips therefore often signal stress during flowering or grain fill.

Varieties that fill to the tip carry more kernels on the same ear length. The trait is influenced by plant density and growing conditions as well as by genetics.

## Why does it matter when choosing seed?

A variety with good tip fill helps hold kernel numbers per ear even in stressful years, which feeds directly into grain yield.
