Abstract
Germination of rape (Brassica napus L.) seed exposed to ethyl methanesulfonate (EMS) for 12 hr at 20–25 C was differentially affected by EMS concentration, pH of treatment solution, seed size, and strain treated. All first order interactions among treatments, except EMS concentration × strain, significantly affected germination. Increasing EMS concentration from 0 to 1.0% adversely affected germination, plant vigor, and seed yield and increased the number of abnormal plants and the days to maturity in M 1 populations. The types of plant abnormalities observed following EMS treatment are described.
