Abstract. Lenawaty DY, Sukma D, Syukur M, Suprapta DN, Nurcholis W, Aisyah SI. 2022. Increasing the diversity of marigold (Tagetes sp.) by acute and chronic chemical induced mutation of EMS (Ethyl Methane Sulfonate). Biodiversitas 23: 1399-1407. Increasing the diversity of marigold (Tagetes sp.) can be carried out through chemical induction mutations with Ethyl Methane Sulfonate (EMS).This study aims to obtain the LC50value, determine the sensitivity level of plants, and obtain plant diversity of Tagetes sp.with EMS both acutely and chronically. The genetic material used in this study was derived from T. erecta genotype MG04 and T. patula genotype MG21. The acute mutation technique was performed by soaking the seeds in EMS concentration for 4 hours under 10 different concentration levels (0%, 0.2%, 0.4%, 0.6%, 0.8%, 1.0%, 1.5%, 2.0%, and 3.0%). The chronic mutation technique was carried out by diluting the concentration of EMS LC501/10x, 1/100x, 1/1000x and immersion time of 6 hours, 24 hours and 48 hours. The study used a Completely Randomized Block Design. Observationswere made on the percentage of surviving plants, quantitative and qualitative characters. The data obtained were analyzed using Boxplot and ANOVA. The results showed that the LC50 value of T. erecta is 0.82% and LC50of T. patula is 1.87%, which means that the sensitivity level of T. erecta to EMS treatment is quite higher than T. patula. The acute application method shows a relatively low mutation rate and limited diversity of flower types. The chronic application method produced various flower shapes and whiter flower color in T. erectaand T. patula resulting in a redder flower color than the acute application method.

Abstract

Abstract. Rahmi HA, Syukur M, Sukma D, Aisyah SI. 2024. Diversity of quantitative, qualitative, and vitamin C content characteristics in F5 generation of chili pepper Capsicum baccatum species. Biodiversitas 25: 2878-2886. Chili is a popular vegetable worldwide, and Indonesia is one of the largest chili producers. However, the cultivation of Capsicum baccatum species is still uncommon in Indonesia. This study aimed to assess the diversity and heritability of yield and yield quality of F5 populations of C. baccatum. This study was conducted at the Experimental Field of Perumahan Alam Sinar Sari, Bogor. The experiment followed a randomized complete block design (RCBD) using 12 genotypes with three replications and four sample plants per replication. The F5 populations of the following genotypes were used: 4k-6p, 4k-7p, 7m-4q, 2m-2m, 7m-3q, 7m-3m, 7m-2q, 2m-2q, 7m-8m, 7m-1m, Bishop Crown, and Lemon Drop. The observations included quantitative, qualitative character,vitamin C contents, and soluble solids. The results showed that the fruit weight per plant ranged from 37.73 to 94.24 grams, while the number of fruits per plant ranged from 11.46 to 30.95. Fruit length ranged from 2.65 to 6.08 cm, and fruit diameter ranged from 15.70 to 41.43 mm. The weight per fruit ranged from 3.43 to 14.89 grams. Brightness or L* values ranged from 19.06 to 41.93, a* values ranged from 5.62 to 31.49, and b* values ranged from 22.90 to 57.45. The chroma value ranged from 30.87 to 64.20, and the hue value ranged from 46.54 to 80.23. The analysis of vitamin C content showed a range of 12.20 to 17.74 mg/20 g, and the test results of soluble solids ranged from 8.77% to 13.49%. All quantitative characters showed high heritability, indicating a strong genetic influence on these characters. The qualitative observations were analyzed, and the results showed that the 12 C. baccatum chilies had similarity coefficients ranging from 0.0 to 0.5. The similarity analysis resulted in grouping the 12 genotypes of C. baccatum into four main groups.
