Summary Temporal changes in shattering losses of 14 wheat (Triticum aestivum L.) genotypes were studied in an irrigated environment. The lines ranged in height from 68 to 98 cm; eight lines were fully awned while five were not. Shattered kernels were gathered at weekly intervals for 6 wk; samping commenced at 30 to 40% kernel moisture and continued for 3 wk beyond harvest ripeness (14.5% moisture). Shattering loss, expressed as a percentage of yield, ranged from 3.25 to 17.3% over the 6 wk period. Awnedness was not a factor in shattering susceptibility of the genotypes studied. Both the most and least shattering resistant lines in this study were awnless. There was a nonsignificant correlation between shattering losses and plant height. It was concluded that a single quantitative measurement of shattering loss at or after harvest ripeness (14.5% moisture) would provide an adequate measure of shattering susceptibility.
