Abstract

This study aimed to obtain information stability results 14 tomato genotypes grown in four lowland locations using multiple methods of parametric stability analysis. The experiments were conducted at four locations, namely Purwakarta, Lombok, Tajur and Leuwikopo. Experiments at each location using Randomized Complete Block Design (RCBD) with three replications which replicates nested within location. The method used were Francis and Kannenberg, Wrickle ekovalens, Finlay and Wilkinson, Eberhart and Russel, Wrickle ekovalens and AMMI . Research carried out shows based on the concept of static stability using the method of Francis and Kannenberg and Russell Eberhart, who declared stable genotype were IPBT3, IPBT53 and IPBT78. Based on the concept of dynamic stability using Wrikle ekovalens and Finlay & Wilkinson methods, stable genotype were IPBT3, IPBT8, IPBT33, IPBT34, IPBT57, IPBT60, IPBT64 and Intan. IPBT3, IPBT33, IPBT34, IPBT60 and Intan as stable genotypes under AMMI methods.

Abstract

This study aimed to obtain information yield stability of 14 tomato genotypes grown in four lowland locations using some nonparametric methods of stability analysis. The experiments were conducted at four locations, there was Purwakarta, Lombok, Tajur and Leuwikopo. Experiments at each location using Randomized Complete Block Design (RCBD) with three replications which replicates nested within location. Based on nonparametric stability index values, the stable genotypes in the lowlands by the Thennarassu and Nassar & Huehn methods were IPBT33, IPBT34 and IPBT60 with the productivity respectively 15.69, 18,37 and 20,26 tonnes ha–1.

Abstract

Sea water can be an alternative source of nutrition for plants. This research aims to obtain the best application concentration of sea water as a source of micro mineral nutrients for the growth of shallot plants. This research was carried out in Loang Baloq, Mataram, West Nusa Tenggara from June 2023 to August 2023. The experiment used a Completely Randomized Design (CRD) arranged in a factorial manner (2 factors, 4 replications). The first factor tested was the salt sea water concentration (K) which consisted of 4 levels, namely: K0 = no sea water; K1 = ratio of sea water and regular water 25 ml: 75 ml, K2 = ratio of sea water and regular water 50 ml: 50 ml. K3 = ratio of sea water and ordinary water 75 ml: 25 ml. K4 = 100 ml sea water. The second factor is variety (V) which consists of 2 levels, namely: T = Tajuk variety, L = Biru Lancor variety. The results of the research showed that giving sea water to shallot plants had a different effect on vegetative growth for the Biru Lancor variety and the Tajuk variety. The treatment showed that the higher the concentration, the lower the growth. Significant results can be seen in the observed characteristics of plant height at 5, 6, 7 WAP and number of leaves a week at 7 WAP. The use of sea water at a concentration of 50 ml gave an increase in positive results for the Biru Lancor variety for the number of shoots in the 7th week.

Abstract

Kedelai (Glycine max (L.) Merril) merupakan tanaman pangan palawija penting yang merupakan salah satu bahan baku industri pangan strategis di Indonesia. Akan tetapi, produktivitasnya masih tergolong rendah. Upaya yang dapat dilakukan dalam meningkatkan produktivitas tanaman kedelai adalah melalui perbaikan genetik antara lain menggunakan mutasi. Tujuan penelitian ini untuk mengetahui keragaman genetik karakter kuantitatif beberapa varietas kedelai generasi pertama hasil mutasi kimia Ethyl Methane Sulfonate. Penelitian ini dilaksanakan pada bulan Juli sampai Desember 2023 di Green House yang berlokasi di Kelurahan Tanjung Karang, Kota Mataram. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) dua factor yang masing-masing diulang tiga kali. Faktor I adalah varietas (V) yang terdiri atas lima varietas: V1=Detam-2, V2=Anjasmoro, V3=Burangrang, V4=Dega-1, V5=Dering. Faktor II adalah konsentrasi penggunaan mutagen kimia EMS (E) yang terdiri atas E0= 0% EMS, E1=0,5% EMS, E2=1% EMS. Data hasil pengamatan selanjutnya dianalisis menggunakan analisis variansi (ANOVA) yang dilanjutkan dengan analisis keragaman genetik dan heritabilitas arti luas melalui perhitungan ragaman genetic dan ragam fenotipik. Hasil penelitian menunjukkan bahwa koefisien keragaman genetic (KKG) karakter kuantitatif kedelai mutan kimia generasi pertama yang tergolong tinggi adalah tinggi tanaman (24,9%), jumlah cabang (84,8%), umur berbunga (23,7%), jumlah biji per tanaman (59,6%), dan bobot 100 biji (37,4%). Sedangkan nilai duga heritabilias arti luas yang tergolong tinggi adalah jumlah cabang (0,8), jumlah buku (0,6), berat kering tajuk (0,5), Panjang akar (0,8), berat kering akar (0,7), umur berbunga (0,7), jumlah polong (0,6), polong hampa (0,8), jumlah biji per tanaman (0,7), berat biji per tanaman (0,8), bobot 100 biji (1).
