SELEKSI MUTAN BATANG PENDEK M3 PADI MENTIK SUSU HASIL IRADIASI SINAR GAMMA

Mentik susu is one of a local rice variety which not widely cultivated due to some unfavourable traits of relatively high plant height and long harvest age. There is an effort done to overcome those problem were plant mutation 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 establish experimental plots for every irradiation doses and comparing the treatment result with the control to identify the effect of irradiation to the growth of Mentik susu. The results shown there were several strains with potential mutants traits based on the positive character of each individual. The M-MS2-15-3 strain with irradiated dose of 200 gray 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 dose has the longest panicle length of 26.83 cm
