| Summary: | The effects of ionic radiation on MR219 Malaysian rice variety were assessed by characterising morphological variances under different water stress treatments. Three third mutant generation (M3) ionic mutant rice lines ML-3, ML-10 and ML-30 were tested under lowest (Tl), moderate (T2), and highest water stress treatment (T3). Results indicated ML-30 performed significantly higher in terms of 100 grain weight and grain weight per plant in all three water stress treatments, while had similar performances compared to other rice lines in terms of flag leaf length, leaf length, number of leaves per plant, panicle length, number of panicles per plant and plant height. ML-30 was observed to performed significantly lower in terms of flag leaf width under the severest water stress treatment (T3). |
