One medium-grain rice variety, six long-grain varieties, and two long-grain hybrids, harvested from 13.4 to 26.0% moisture content (MC) from Keiser, Ark., Stuttgart, Ark., and Alvin, Texas, were used to determine the influence of harvest location andMC on kernel-to-kernel breaking force distributions (BFDs). Harvest MC affected BFDs, however, a greater influence was imposed by the growing location. Head rice yield (HRY) was plotted against the percentage of kernels in a sample having breaking forcesgreater than 20 N, which was used to define "strong" kernels. The strongest correlations between HRY and the percentage of strong kernels were found for variety/growing location lots having low to mid-level HRY levels; little to no correlation was observed for samples having high HRYs.
