“…Upaya lain yang dapat dilakukan untuk mengurangi serangan penyakit karat daun pada tanaman kedelai adalah dengan cara melakukan pemuliaan tanaman pada tanaman kedelai. Seperti yang dilakukan oleh Bayu et al (2017) dan Poniman et al (2020) yang telah membuktikan bahwa beberapa varietas kedelai tahan terhadap serangan hama penggerek polong. Selain itu, pemuliaan tanaman kedelai juga diarahkan pada ketahanan terhadap penyakit, sehingga nantinya akan dihasilkan varietas kedelai yang tahan terhadap penyakti seperti karat daun.…”

Karat daun merupakan salah satu penyakit utama yang menyerang tanaman kedelai yang disebabkan oleh cendawan Phakopsora pachyrizi pada tanaman kedelai. Penurunan hasil produksi yang disebabkan oleh penyakit karat daun ini sebesar 10-90%. Tujuan peneltian ini yaitu untuk mengetahui tingkat ketahanan beberapa genotipe kedelai pada penyakit karat daun. Rancangan penelitian yang digunakan yaitu rancangan acak lengkap dengan 7 genotipe kedelai sebagai perlakuan meliputi GHJ1, GHJ2, GHJ3, GHJ4, GHJ5, Anjasmoro, Ringgit. Parameter pengamatan meliputi, luas permukaan daun, International Working of Soybean Rust (IWGSR), berat biji per tanaman. Data dianalisis dengan SPSS Versi 23.0 yaitu dengan uji ANOVA dan diuji lanjut BNT 5%. Hasil dari penelitian ini menunjukkan bahwa tidak terdapat perbedaan pada luas permukaan daun pada semua genotipe, genotipe GHJ1, GHJ2, GHJ3, GHJ4, GHJ5 memiliki tingkat ketahanan yang tahan terhadap penyakit karat daun, dan untuk varietas Anjasmoro memililiki tingkat ketahanan agak tahan, sedangkan varietas Ringgit memiliki tingkat ketahanan agak rentan pada penyakit karat, berat biji terandah yaitu varietas anjasmoro dengan rata-rata sebesar 3,5 gr pertanaman.

Increasing productivity of soybean has often been constrained by pod sucking bugs (Riptortus spp.) which caused a serious damage and yield losses up to 80%. Breeding for obtaining soybean variety resistant to pod suckers needs the availability of soybean germplasm resistant to the pest. The study aimed to obtain a candidate for soybean variety resistant to Riptortus spp. through the selection of 100 accessions of soybean. The study included the preparation of test plants and test insects, pest infestations, observations, and looking for a practical screening method for pod sucking pests. The experiment used a completely randomized design for two treatments (infested and non-infested Riptortus spp.). Cikuray variety and PI-092734 accession were used as a control. Results showed that there was a very low correlation among variables observed. Twelve soybean accessions showed a resistance to Riptortus spp., i.e. C7301-113AC-POP, Lokal Madiun-3549, Lokal Klungkung, ML.2974, Singgalang, Lokal Jepara, Lokal Jatim, Lokal Trenggalek, Lokal Tulungagung, Lokal Tabanan, Lokal Blitar, and Lokal Kuningan 10. These accessions were more resistant than the popular released variety such as Wilis, Grobogan, Detam 2, and Gepak Ijo. Small seed size was not a major determinant of soybean resistance to pod suckers. The addition of observational components, i.e. probing preference and oviposition, indicated that crop damage was indirectly influenced by the high frequency of probing and oviposition, although its relation to plant tolerant mechanisms still needs further investigation. Indeterminate plant types require further validation as to whether they contribute significantly to plant resistance against pod sucking insects.

“…Persentase kerusakan polong (%) ditentukan atas dasar persamaan (Bayu et al, 2017) : Ciri-ciri polong kedelai terserang hama penggerek polong adalah terdapat lubang gerek berbentuk bundar pada kulit polong. Apabila terdapat dua lubang gerek pada polong berarti ulat sudah meninggalkan polong (Marwoto et al, 2017).…”

[POD BORER ATTACK ON SIX SOYBEAN VARIETIES AND THEIR EFFECTS ON YIELD]. This study aims to determine the level of pod borer attack on six soybean varieties and their effects on yields. This research was conducted from December 2017 to March 2018 in the Experimental Field of the Faculty of Agriculture, University of Bengkulu, Kandang Limun Village, Muara Bangkahulu District, Bengkulu City. The experimental design used was a Randomized Complete Block Design (RCBD) with the treatment of six soybean varieties (Demas, Argomulyo, Dega, Ringing, Echo, and Dena I) and was repeated 4 times so that there were 24 experimental units. The results showed that the percentage of pod attack on the Demas, Argomulyo, Ringing, Gema, and Dena I varieties was classified as resistant, while the Dega variety was relatively resistant. Whereas the percentage of seed attack in all soybean varieties tested was classified as resistant. Argomulyo varieties have higher resistance to pod borer attack than other varieties because they produce the highest number of trichomes, and the lowest number of larvae per plant. Argomulyo variety produces the highest number of seed weight per plant, and the highest seed weight per plot. The echo variety produces the highest number of total pods, while the Dega variety produces the highest weight of 100 seeds.
