ABSTRACT

Rojolele is a local prime variety that hasn’t been cultivated well by our farmers because of their lacks such as long harvest time needed, over height stem, and pest de-resistance. So there should be enhancement of Rojolele’s quality, one way to achieve it is by induction mutation using radiation of gamma ray. This research is targeted to select better quality of radiated plant compared with their previous plants. This research takes place on field around Nangsri Lor Village, Kebakkramat, Karanganyar. This research was held and organized in a squared experimentation of examining every plants with radiation and compare them with controlled plants to find out their differences and the effect of radiation to Rojolele’s growth. Result showed 20 strains with mutant potential, based on their positive character of their each individuals. Strain T112 with radiation dosage of 300 grays has very short height of 127cm, strain T10 with 200 grays of radiation dosage has tallest panicle of 39,5cm, strain T20 with 200 grays of radiation dosage has highest number of tiller of 10 stems, strain T121 with 100 grays of radiation dosage has 8 stems of stems, which is the highest number of tillers productivity, strains T30 with 200 grays of radiation dosage has highest number of filled unhulled rice of 1104 pulps and strains T77 with 300 grays of radiation dosage has highest percentage of filled unhulled rice of 97,25% and strains T(1-4) with 100 grays and T(1-5) with 200 grays of radiation dosage has shortest harvest time of 142 days.
