“…Moreover, 600 Gy produced the highest anthocyanin in rosella (Hisbiscus sabdariffa) (El Sherif, Khattab, Ghoname, Salem, & Radwan, 2011). Genetic variability both morphology and biochemical substance can be used to select expected lines which have good characters (Mustikarini, Ardiarini, Basuki, & Kuswanto, 2017).…”

Black Rice is rice producing anthocyanin in high intensity and popularly consumed as functional food. Long harvesting age and low productivity are the inhibiting factors in black rice breeding. High plant crown potentially results in plant fall-down. Mutation induction is expected to be able to improve the character of black rice. Therefore, the objectives of this research were to get more early-ripening black rice mutant, with shorter plant crown and increase productivity by inducing mutation in three varieties of local black rice using gamma-ray radiation. This experiment employed three local varieties as the first factor comprised Cempo Ireng, Cempo Melik and Melik. The second factor was the gamma-ray radiation dose, consisting of 4 levels: without radiation, radiations at 100 Gy, 200 Gy and 300 Gy doses. The results indicated that Melik variety is very potential. Melik variety has shorter plant crown with a responsive character in number of tiller for higher productivity. Moreover, radiation significantly reduces the duration of flowering and harvesting. However, to achieve a more stable character and lower flowering and harvesting period, the radiation needs to be continued in the next generation. The doses of radiation produces a response that varies in both morphological and biochemical properties.

“…But, it is not recommended that the selection of local line of Bambara groundnut to be based on quantitative characters. The selection strategy should be able to single out genotype which has excellent genes and is still expressed in every condition (Mustikarini, Ardiarini, Basuki, & Kuswanto, 2017). The other characters had high response to environment and controlled by polygenic.…”

The main problem of local line Bambara groundnut (Vigna subterranea L. Verdcourt) genotype improving is the low of purity. The research on genetic purification of Bambara groundnut had finished in twice single seed descent. The objective of this research was to find out the uniformity gain level within lines each other after single seed descent applied twice. This research was conducted in Agriculture Research Station, Universitas Brawijaya, from 2014 to 2016. There were 20 selected local lines evaluated twice with single seed descent method. On the first and second evaluation, it was applied on previous 19 local lines and 1 check genotype. Similarity coefficient was analyzed with cluster analysis of qualitative characters within lines. Variability within line was described on quantitative characters. The local lines had different response on single seed descent selection. These differences depended on genetic of qualitative characters. On the first single seed descent, it got similarity coefficient of 0.704-0.832. On the second one, it got similarity coefficient of 0.804-1.00. Increasing of similarity coefficient from 0.10-0.168 will improve purification of local lines 15.76-20.19 %. Two circles of single seed descent selection were capable to purify local lines. Variability of quantitative character depended on kind of character.

“…The selection method using stress in the critical period obtained the M5-GR150-1-9-13 line of red rice that was drought tolerant (Mustikarini et al 2016). Drought stress applied to the booting stage showed the most significant effect on decreasing various parameters of the selection of drought-tolerant rice lines (Mustikarini et al 2017).…”

Abstract. Mustikarini ED, Lestari T, Santi R, Prayoga GI, Cahya Z. 2022. Short Communication: Evaluation of F6 generation of upland rice promising lines for drought stress tolerance. Biodiversitas 23: 3401-3406. Water is important in metabolic processes affecting rice crop growth and development. Drought stress can decrease rice production, necessitating the development ofdrought-tolerant varieties. Selection of drought-tolerant can be done during the critical period plant booting phase. Thisresearch aimed to determine promising linesof upland rice tolerant to drought stress. This research was conducted from December 2019 toMay 2020 at the experimental farmofthe Faculty of Agriculture, Fisheries and Biology, Universitas Bangka Belitung. The research was laid out in a completely randomized design with a single-factortreatment. The treatment was rice genotypes consisting of 10 lines and 2 checkvarieties; each was 3 replicates. The results showed that the droughtstressin the plant booting phase of rice plants significantly affected the plant heigh character of the plant, grains number per panicle, the weight of grain per panicle, the age of flowering, and harvest time, but gave no significant effect on the number of leaves, the number of productive tillers, roots length. The upland rice lines 23A-56-30-25-1, 23A-56-30-25-12, and 23A-56-30-25-13 showed good drought stress tolerance based on leaf rolling, leaf drying, crop yield, and plant growth percentage.
