【 摘 要 】

Mentik Susu is one of a local rice variety, which is not widely cultivated due to some unfavourable traits which were relatively high plant height and long harvest age. Efforts were done to overcome the problems such as planting mutation-induced plants through the utilization of gamma-ray irradiation. The objective of this research was to observe and select M3 mutants of Mentik Susu from gamma ray irradiation and obtain short-stemmed mutant plants. The research was conducted by simple design experiments (SDR). Established experimental plots for every irradiation doses and comparing the treatment result with the control to identify the effect of irradiation on the growth of Mentik Susu. The result showed that there were several strains with potential mutant traits based on the positive character of each individual. The M-MS2-15-3 strain with an irradiated dose of 200 grays has the shortest plant height of 92.10 cm with the highest productive tiller of 27.40 stems, has the highest seed yield per plant of 91.00 gram and has the shortest harvest age of 88 days. The M-MS2-15-4 strain with 200 gray irradiation dosehas the longest panicle length of 26.83 cm.
