Abstract

Sebagian besar pertanaman kedelai berada pada musim musim kering (MK), namun justru tingkat serangan hama paling tinggi terjadi pada waktu itu. Salah satu hama penting yang menyerang tanaman kedelai adalah lalat kacang (O phaseoli ). Serangan hama lalat kacang pada tanaman kedelai dapat mengakibatkan kerusakan hingga mencapai 90 %, tergantung tingkat serangannya dan sebagian besar tanaman mengalami kematian. Kedelai yang toleran terhadap lalat kacang diidentifikasi memiliki karakter diameter batang kecil. Varietas unggul tahan hama lalat kacang merupakan cara yang efektif dan efisien untuk dapat menekan serangannya. Untuk merancang varietas kedelai unggul toleran lalat kacang memiliki peluang besar dengan mempertimbangkan ketersediaan sumber-sumber gen tahan pada tanaman serta memilih metode pemuliaan yang efektif dan efisien.

Abstract

Meningkatnya permintaan kedelai hitam oleh industri, menimbulkan kembali minat petani untuk menanam kedelai hitam. Pemerintah baru berhasil melepas dua varietas kedelai hitam berdaya hasil tinggi (selain tiga varietas unggul lama, Otau, No 27 dan Merapi) yakni Cikuray (dilepas tahun 1992) dan Mallika (dilepas 2007). Ciri utama varietas tersebut adalah ukuran bijinya berkriteria sedang yaitu sekitar 10 g/100 biji. Perbaikan potensi hasil kedelai hitam serta ukuran biji dan karakter lainnya, diupayakan melalui pembentukan populasi dengan menggunakan kedelai hitam introduksi berukuran biji besar disilangkan dengan varietas kedelai berdaya hasil tinggi. Seleksi dan uji daya hasil mendapatkan tiga galur kedelai hitam prospektif yakni 9837/K-D-8-185, W/9837-D-6-220; dan 9837/W-D-5-211. Pengujian di 18 sentra produksi membuktikan bahwa galur 9837/K-D-8-185, W/9837-D-6-220; dan 9837/W-D-5-211 berdaya hasil 18% lebih tinggi dibandingkan varietas kedelai hitam Cikuray (2,03 t/ha). Tiga galur kedelai hitam tersebut memiliki karakter unik. Galur 9837/K-D-8-185 memiliki ukuran biji 14,84 g/100 biji, dan akan menjadi kedelai hitam pertama berukuran biji besar sekaligus memiliki kandungan protein tinggi (45,36 %). Galur 9837/W-D-5-211 akan menjadi varietas kedelai hitam dengan kandungan protein tertinggi (45,58 %) dari seluruh varietas kedelai yang ada di Indonesia. Sedangkan keunikan galur W/9837-D-6-220 adalah berkotiledon hijau (green kernel), dan akan menjadi varietas kedelai pertama di Indonesia yang memiliki warna kotiledon hijau. Tiga galur tersebut sudah diusulkan untuk dilepas sebagai varietas unggul.

ABSTRACTThe Examination of 15 Soybean Genotypes at 50% Light Intensity and Evaluation of Crop’sPhenotypic Characters. Sunlight is one of the important plant growth requirements. In orderto understand morphological character changes in the crops due to different light intensity, 15genotypes of soybean consisted of Willis, D3578-3/3072-11, Seulawah, Aochi/W-62, Kaba,IAC 100/Brr-1, MLGG 0081, MLGG 0059, MLGG 0120, 9837/Kawi, D-6-185, IAC 100, MLGG0383-1, Pangrango, MLGG 0069 and MLGG 0122 were tested. The research was conducted inKendalpayak (grey Alluvial soil type, 450 above sea level, C3 climate type), Malang at dryseason in 2006. The research design was Randomize Complete Block under two differentenvironmental conditions, with three replications. The experiment was conducted under fulland 50 %light intensity. The results indicated that the reduction of light intensity as much as50 % resulted in some changes in phenotypic characters such as size and lifespan of the 15genotype being tested, included the increase of plant height, the longer distance betweennodes, the decrease in node number, the smaller size of stem diameter, the decrease on thenumber of leaves, the narrower of the leaf ‘s width and the decrease in pod number. Lessenedseed weight, the low weight of 100 seeds, the lowering level of the leaf’s greenness, and theaccelerate age of flowering and harvesting. IAC 100, MLGG 0383-1 and IAC 100/BBR-1 producedhigh under 50% of light intensity.Keywords : Soybean (Glycine max (L) Merrill), light intensity, phenotypic

Abstract

Identification of soybean genotypes including potential yield character is a base to understand soybean growth, development, and productivity on potential lands. The purpose of this research is to determine the potential yield of soybean genotype in tidal land type C and their supporting components. Four soybean genotypes and two comparative varieties Anjasmoro and Lawit (adaptive tidal land) were tested on tidal land type C at four locations (three locations in Jambi Province and one location in South Kalimantan Province), July 2017. The research was conducted using a randomized design for each location and repeated four times. The plot size was 12 m2, spacing row 40 cm x 15 cm, two plants for each hole. GH_KR_13, GH_GR_1 and  GH_GR_5 productivity equal with Lawit, the adaptive variety for tidal land type C. While, Anjasmoro showed more than 2.20 t/ha in seeds productivity, 54 filled pod for each plant, with large size of seeds (15.84 gram/100 seeds). Anjasmoro had higher seed productivity than all of genotypes including Lawit. Anjasmoro with it?s potential yield and productivity, can become farmer preferences and deserve to be developed in tidal land type C.

Abstract

Excessive shading during plant growth is one of the factors that might decrease the productivity of crops. The aim of this study was to determine agronomic characters of soybean germplasms grown under shaded environment. The research was carried out at Kendalpayak experimental station (grey Alluvial soil, 450 m above the sea level with C3 climate type) during dry season in Malang, from February to April 2006. The experimental design used was Randomized Complete Block Design with three replications. The genetic material observed were 120 accessions of Balitkabi’s soybean germplasm; the treatments were without shading and 50% shading using shading net. The results showed that 50% shading decreased plant age to harvest, increased plant height, and reduced the number of pods and seed weight compared to those in no shading environment. Based on Stress Tolerancy Index (STI) analysis on the seed weight per plant, fi ve accessions i.e. MLGG 0845, MLGG 3335, MLGG 0010, MLGG 0771, and Wilis demonstrated high tolerance on 50% shade
