Abstract Cempo Ireng rice is local rice that is rich in anthocyanins. The issue with Cempo Ireng rice is its lengthy harvest life, high habitus, and low production. Plant mutations are one method for overcoming this. The study’s goal is to create better mutant plants with high yields. The study was conducted by placing three lines in plots from December 2019 to August 2020. The results were descriptively evaluated and compared to the control using the T-test. The results showed that the mutant plant was superior to black rice without irradiation (control). The line with the highest productivity value (per hectare) was line 51 which was 8.45 tons/ha. Line 44 has the highest average anthocyanin content of 75.10 ppm.

Abstract Black rice is one of the local Indonesian rice varieties contains high anthocyanins. This research used the treatment of three different strains resulting from gamma ray irradiation (strain 8, 44 and 51) and control (without irradiation). The data was analyzed descriptively and qualitatively to compare three strains of black rice irradiated by gamma ray with control (without irradiation). The result showed that the three strains of black rice “Cempo Ireng” irradiated by gamma ray had better yield quality and performance compare to control (without irradiation). Strain 44 was the strain with the highest anthocyanin content of 75.11 ppm and the best performing strain (organoleptic score of 3.53 and seed pericarp color of 4). Strain 51 had the best amylose content (8.43%), the highest protein content (7.48%), the highest fat content (1.59%), the best vigor (80%) and seed viability (64%).

Abstract Black rice is a functional food plant with high fiber and anthocyanin content. It has a weakness that is a high content of amylose which causes rice texture to harden. The study used a different treatment of the plant line, namely three promising lines of irradiated black rice M7 (lines 13, 46, and 52) and lines without irradiation (control). The data were analyzed descriptively and qualitatively. The results showed that the three promising lines had better yield quality and performance than the control plants. The highest anthocyanin content and the best fat content were found in line 52, which were 75.04 ppm and 1.35%. Line 46 had the best protein content, vigor, and viability of 7.88%, 88%, and 67%, respectively. Line 13 had the highest amylose content of 14.92%. Line 52 was the best performing line (organoleptic staining and seed pericarp) compared to the other lines, namely 3.25 and 3.

Abstract Gamma-ray irradiation on Cempo Ireng can lead to the variation of morphological characteristics; hence, morphological characterization is necessary to determine changes in potential lines. This research aimed to characterize the potential lines as one of the requirements for proposing plant variety release and add black rice genetic diversity information. The research was carried out in the rice fields of Pakahan Village, Jogonalan, Klaten in January-June 2020 with the arrangement of potential lines 8,13 and 44 of M6 in a row. In total 30 plants were selected randomly for each potential line and observed 19 morphological characters. Data analysis was carried out descriptively and qualitatively with the Chi-Square test. The results showed that gamma-ray irradiation affects the characters of leaf angle, auricle color, ligule color, leaf-blade color, leaf surface, panicle type, grain color, apiculus color, and rice length. Potential line 8 had different characteristics compared to non-irradiated Cempo Ireng in the characters of auricle color, leaf-blade color, leaf width, panicle length, grain width, rice length, and rice width, while on potential lines 13 and 44 occur in the characters of the leaf surface and panicle length.

Abstract The aims of this study to determine the growth and leaf chlorophyll content in black rice (Oryza sativa L. Indica) which were induced by gamma rays as responses to the drought stress conditions. This study was carried out on July–November 2020, at the experimental field (screenhouse), Medicinae Street, UNS Perum, Jati Village, Jaten District, Karanganyar Regency. Meanwhile, the chlorophyll content test was carried out at Plant Tissue Culture and Biotechnology Laboratory, Faculty of Agriculture, Universitas Sebelas Maret. The study was a field trial research design without replication. The research treatments were 24 genotypes as follows: 10 genotypes of 100 gray gamma-ray irradiation with 2 control genotypes; and 10 genotypes of 200 gray gamma-irradiation with 2 control genotypes. The results showed that the plant height was lower in plants with irradiation compared to the Control-01 plant. The crown-root ratio showed irradiated plants had higher average results than control plants. The leaf chlorophyll of 100 gray irradiated plants showed higher results than control; while 200 gray irradiated plants showed similar results.

Increasing the genetic diversity of plants can be done through physical mutations with gamma-ray irradiation. This study aims to determine gamma-ray irradiation on the growth of six M1 generation black rice accessions. This research was conducted in May-October 2019 at the Experimental Rice Fields of the Tasikmalaya Perjuangan University, West Java. The materials used in this study were six accessions from Tasikmalaya (PH, PH2, PH3, PH5, PH7, and PH8) without 0 Gy irradiation and with 200 Gy gamma-ray irradiation of M1 generation. The results showed that gamma-ray irradiation reduced germination characteristics, seedling height, and flowering age. Some of the accessions showed different effects; there were a decrease and an increase in the characters of root length, plant height, number of productive tillers, number of unproductive tillers, and the total number of tillers.
