Stability Test For Sorghum Mutant Lines Derived From Induced Mutations with Gamma-Ray Irradiation

Badshah Bhog is a non basmati aromatic traditional rice cultivar. which is not widely cultivated due to some unfavourable traits which were relatively high plant height, late maturity and low average yield. By the utilization of gamma ray irradiation in plant breeding attempted to overcome such problems in crops. The objective of this research is to observe and select M2 mutants of Badshah Bhog from gamma ray irradiation and obtain early maturing short stature plants. The research was conducted by Line sowing method. Established experimental plots for every irradiation doses and comparing the treatment result with the control to identify the effect of irradiation on the growth of Badshah Bhog. The result showed that there have been several plants with potential mutant traits supported the positive and negative character of every individual. The irradiated dose of 300 Grays has the shortest maturity duration of 131 days with the highest productive tiller of 6.67 but very low as compared to control. The irradiated dose of 400 Grays has the shortest Plant height of 97.8 cm. The plant yield of mutant lines in the present study was not affected significantly in any direction which could due to occurrence of polygenic mutations with ‘plus’ and ‘minus’ effect equally distributed. Together with short stature plants also plants bearing double spikelet at tip and mid region of panicle observed.

High Seed Yield

Current breeding efforts in soybean largely focus on identifying genotypes with high seed yield and large seed size. Our study applied a mutation using 250 Gy Gamma-Ray Irradiation to soybean cv. Anjasari. The variability in the M1 generation was identified, and the planting was continued to M2 M3, M4, M5 until M6 generation. The objectives of this research were to evaluate mutant lines exhibiting a good performance in yield and morphological characteristics that can support the yield component in M6 generation. This research was conducted from January 2019 to May 2019 at Ciparanje Experiment Station, Faculty of Agriculture, Universitas Padjadjaran, Jatinangor, West Java. The experiment was arranged in a Randomized Completely Block Design with fifteen mutant soybean genotypes as treatments with two replications within each treatment. The results showed several genotypes produced higher yield and better agro-morphological characteristics. The genotypes MR-33, MR-4A, and MR-2A showed significantly higher number of total pods per plant. Meanwhile, the genotypes MR-35A, MR-37, MR-23, MR-36A, MR-3A, MR-29A MR-34A, MR-4A, MR-17, and MR-5A showed a higher value in weight of 100 seeds. The highest yield was observed in MR-29A and MR-23, which then will be used as the genotypes for multilocation test for stability.

Lestari T, Mustikarini ED, Apriyadi R, Anwar S. 2019. Early stability test of mutant candidates of Bangka local cassava, Indonesia. Biodiversitas 20: 337-342. Cassava production in Indonesia has decreased due to decreased harvest area. Increasing production can be done by improving genetic diversity through gamma-ray irradiation to create high production mutant. The purpose of this study was to determine the optimum irradiation doses in relation to improve production of local cassava from Bangka Island, as well as morphological changes resulting from the irradiation. The research was conducted at the Experimental Garden, the University of Bangka Belitung, Indonesia in September 2017 until April 2018. This experiment was using Split Plot design, with the main plot consisted of 2 levels and subplot have 3 treatment levels, and 4 replications, in total there were 24 experimental units. The results showed that gamma-ray irradiation had very significant effect on plant height, number of leaves, young leaf color, stem color, and number of lobes. Gamma-ray irradiation on 3 Bulan accession showed an improved tuber production, whereas in Malang varieties gamma-ray irradiation decreased tuber production. Gamma-ray irradiation dose of 30 Gray was able to improve the number of tubers, tuber weight and starch content on 3 Bulan cassava accession.
