<p style="text-align: justify;">The rice line PWC16 was isolated from a population derived from seed of the variety &lsquo;Cypress&rsquo; which had been treated with ethyl methanesulfonate (EMS), a substance know to induce point mutations within the genome of organisms. The selection of herbicide tolerant plants was made from whole plants treated with imazethapyr. The designation of PWC16 was given to the imazethapyr-tolerant plant selected from the population. Seed increase was achieved through self-pollination or natural (wind) pollination occurring among plants of this line.</p>
