Â Stevia rebaudiana Bert. (Stevia) is used in the commercial and health industries because of its steviol glycosides (stevioside, reÂbaudioside A, rebaudioside C) and flavonoids. Polyploidy induction of stevia plants using oryzalin was held to increase the diversity and produce superior varieties. This research aims to obtain stevia diverÂsity with different characteristics from its diploid. The TawangmanÂgu variety of stevia seedlings was experimentally designed using a completely random design. Nine combinations of oryzalin concentraÂtions (1.5, 2.5, and 3.5Î¼M) and immersion times (4, 6, and 8 hours) treatments were applied to 15 stevia seedlings each. Stevia without treatment was used as a control. Treatments were applied directly to the shoots on the second internode from the tip. Observations on tarÂget shoots included the number of survivors, morphological variables (height, number of internodes, internode length, leaf size, leaf thickÂness, stem diameter, and leaf color), stomata, and plant ploidy level. Data analysis on the number of live plants used frequency and deÂscriptively. Morphological data consisting of plant height, number of shoots, number of internodes, internode length, leaf length, leaf width, leaf thickness, and stem diameter were analyzed using boxplot graphs and descriptive to describe the diversity of M1 stevia treatment reÂsults. Leaf color and stomata were analyzed descriptively. The results showed that up to 3.5Î¼M concentrations of oryzalin and 6 hours of immersion time were safe to use as a mutation agent with above 67% survival rate. Various oryzalin treatments of Tawangmangu stevia vaÂrieties yielded polyploidy morphological growth indications in height, number of internodes, internode length, stem diameter, leaf size, leaf thickness, leaf color, stomata, and stem diameter. In addition, there are growth variations such as chimeras, rosettes, and leaf splitting. However, further flow cytometry tests showed that oryzalin concenÂtration and immersion duration directly on the vegetative material did not produce polyploid stevia individuals.

Eating black rice can avoid the risk, reduce insulin in the body, bind free radicals, and reduce weight. However, black rice still has disadvantages, like long life, tall stems, less resistance to pests and diseases, and low yields. Activities were carried out from August 2023 to November 2023 in Pakahan Village, Jogonalan, Klaten. The planting materials used were selected M3 mutant black rice seeds irradiated with 200 Gy gamma rays and Cempo Ireng black rice as a control plant. Planting used a randomized complete block design without replication with the pedigree selection method. The parameters measured were harvest age, plant height, productive tillers, and seed weight per plant. Descriptive analysis was used and a 5% level T test was carried out to compare the characteristics of the M4 genotype with the control (without irradiation). The research results showed that 12 individuals containing high lignin were selected which could be further developed for the next generation.

Mentik Susu is a popular rice germplasm in Indonesia. Due to field constraints in Mentik Susu rice cultivation, farmers switched to better varieties with higher yields. Farmers switch to superior types with high yields due to high plant posture, long harvest life, and low yields. Rice plants usually have a protein content of 4-5% per gram while without given radiation. It will be expected that after receiving gamma rays, the protein content in mutant plants will increase up to 7-8% per gram. The aim of this research was to evaluate the productivity and protein content of rice grain of 35 mutant strains of rices that could be developed into new varieties. The research took place at the Tegalgondo Rice Seed Garden Agricultural Land between June to October 2020. This research used Randomized Complete Block Design method with a single factor. Each treatment was repeated three times. The data obtained was analyzed with analysis of variance and followed with Duncan’s Multiple Range Test at a 5% level if any significant influences. The results of this research showed productivity of 35 Mentik Susu rice lines ranged from 4.28 to 6.69 ha-1, with either a high protein content ranging from 5-8% per gram and intermediate high yield potential strains G63T11-B6-T27(1), G15T5-14-B5-T60, G15T5-14-B5-T46, G11T22-19-B1-T48, G15T5-14-B3-T36, M-MS2-G15T3-2-5 -T27, M-MS2-G18T7-4-12-T13, M-MS2-G18T7-4-9-T12. These strains might be cultivated as potential candidates for new high-yielding varieties, which would then be evaluated for higher yields or multilocation tests before becoming published as new varieties.

Most farmers determine the cutting of air layer seed in a corp through the amount of the growing roots from air layer itself. The roots can be an indicator of air layer cutting method in a corp. The roots, which are too old or too young, grow less optimal in the air layer seed after being transferred into another cultivated medium. It is necessary to have knowledge about the precise age of air layer cutting so that the vegetative propagation by using air layer can be performed accurately and efficiently. The treatment that is executed is the age of air layer and the corps accession. The result of this research indicates that the effect of the difference air layer age on plant growth is at the age of emerging buds, aged 180 Day is treated with the age of the fastest emerging shoots. The growth of Bojonegoro air layer plants results that does not differ with Wonogiri air layer plants. There is no interaction between air layer age with sapodilla accession on plant growth.

The demand for rice in Indonesia continues to increase but production has decreased. Efforts that can be made are the use of local varieties of mentik wangi rice. Mentik wangi rice has the disadvantages of long life, high stems, and low crop production. As a solution, plant breeding is carried out in the form of mutation by giving gamma irradiation which can improve unwanted genetic traits and produce superior varieties with the dose used of 200 gray. This study aims to evaluate the yield potential of promising mutant strains with 200 gray gamma irradiation on mentik wangi rice and get mutant strains that have superior criteria for short-stemmed, short-lived, and high-yielding. This research was conducted in the rice field of Ngampel Hamlet, Gentungan Village, Mojogedang, Karanganyar, Central Java. The research was conducted in June-October 2023. The design used was a Randomized Complete Group Design (RCBD) with a single factor, namely strains consisting of 14 mutant strains and 1 control strain with 3 repetitions. The results of observations were analyzed by Analysis of Variance (ANOVA) at the 5% level and continued with Duncan Multiple Range Test (DMRT) at the 5% level. All tested strains produced the expected superior criteria, namely short stem, short age, and high productivity.
