  • KERAGAAN KEDELAI (Glycine max.) GENERASI M1 HASIL MUTASI VARIETAS DEGA 1
           DENGAN BEBERAPA KONSENTRASI Ethyl Methane Sulphonate

    • Authors: Aslim Rasyad, Bondan Fiarahman
      Pages: 1 - 10
      Abstract: Increasing soybean productivity required some effort as one is to develop new high-yielding varieties or improve existing varieties. To obtain an improved variety, one needs to obtain a population with high genetic variability to ease the selection of new suitable cultivars. In this study, we used to induce mutations using chemical mutagen, ie, Ethyl Methane Sulphonate (EMS), to increase the variability. This research had been conducted in the Plant Breeding Laboratory and the experimental farm of Riau University. Seeds of Dega-1 Variety were soaked in the solution of EMS in buffer phosphate within several concentrations ie, 200 ppm, 300 ppm, 400 ppm, 500 ppm, 600 ppm, and 700 ppm. The seed then were washed with aquadest to clean the remaining EMS solution and then planted together by initial Dega-1 as the control in the field experiment using a completely randomized design (RAL) with four replications. Parameters observed were plant height, number of internodes the age of flowering, age of harvest, number of pods per plant, number of filled pods per plant, number of seeds per plant, seed weight per plant, number of seeds per pod, and type of growth, flower color, and pod color. Population variances were calculated by Microsoft Excel software. The homogeneity of the variance was tested with HOV by the procedures of Levene’s test. The results showed that the induction of mutations with 200 ppm of EMS increased genetic variance in M1 generation compared to the Dega 1 variety for the most quantitative character, including plant height, number of pods per plant, number of filled pods per plant, number of seeds per plant, and seed weight per plant. Induce that the mutation by EMS solution, on the other hand, didn’t change all qualitative characters.

      Abstract: The main pest that attacks cocoa crops is Helopeltis theivora Waterhouse. The Helopeltis theivora pest can cause a loss of 60%. Helopeltis theivora pest control generally still uses synthetic chemical insecticides because they can control pests quickly and efficiently. The control using botanical pesticide extracts of forest betel fruit (Piper aduncum L.) is an alternative to overcome the impacts caused by the use of synthetic insecticides. This study aimed to increase the concentration of forest betel powder extract to obtain an effective concentration to control Helopeltis theivora. The research was conducted at the Laboratory of Plant Pests and Experimental Farm, Faculty of Agriculture, Riau University. This study was conducted from August to September 2020. The research used a completely randomized design (CRD) with five treatments and four replications to obtain 24 experimental units. The treatments given were the concentration of forest betel fruit powder extract of 6%, 7%, 8%, 9%, and 10%. The results showed that increasing the concentration could increase the effectiveness of forest betel powder extract (Piper aduncum L.) to control Helopeltis theivora which at a concentration of 8% forest betel flour can cause total mortality of 87,50% with an initial time of death at 9 hours after application and lethal time 50 at 39 hours after application.

The method used was a completely randomized design (CRD) with 5 treatments and 3 replications, namely: P1 administration of vermicompost POC at a dose of 0.5 cc/l, P2 giving vermicompost POC at a dose of 1.0 cc/l, P3 giving vermicompost POC at a dose of 1,5 cc/l, P4 was given vermicompost POC at a dose of 2.0 cc/l and P5 was given vermicompost POC at a dose of 2.5 cc/l. From the results of the study, the highest density of Chlorella sp was in treatment P2 with a total density of 14,500,000 cells/ml on day 11. With the lowest average peak in treatment P5 with a total cell count of 6,333,333 cells/ml on day 4. Water quality such as temperatures ranging from 25-30 0C, pH 6.5-7.
