“…The presence of soybean resistance gene sources against pod sucking pests provides an opportunity to obtain a soybean genotype that has a resistance to pod sucking bug. As stated by Krisnawati et al, (2016) that knowledge of the mechanism of resistance will doubtlessly help in the development of soybean variety with improved pest resistance, especially for R. linearis, and may result in reduced insecticide use. Since the soybean resistant variety to pod sucking bug is not yet available in Indonesia, the resistant genotype that may be obtained from this study will be useful as gene source in soybean breeding program, or can be released as new variety.…”

Pod sucking bug, Riptortus linearis, is the most damaging soybean pest in Indonesia. A total of 24 soybean genotypes was identified for their resistance to pod sucking bug. The objective of the study was to classifying the resistance of some soybean genotypes against pod sucking pests. The research was conducted during the second dry season (July - October) 2016 in Ngale Research Station, East Java, Indonesia. The experimental design was arranged in randomized block design with five times repetition and two types of environment (full crop protection and controlled until 50 days of planting/dap). The resistance to pod sucking bug was evaluated based on seed damage, pod damage, and seed weight. The grouping of resistance was by using Chiang & Talekar’s method (1980). A very high natural population of pod sucking bug was recorded in the research area as seen from the average number of damaged pod in full protection environment (L1) and insecticide control until 50 dap (L2), i.e. 41.45% and 60.16%, respectively. Genotype of G511H/Anj//Anj-2-8 was consistently resistant to pod sucking bug in L1 as well as L2. This genotype also had early days to maturity (78 days) and large seed size (15.57 g/100 seed), thus potentially to be developed in tropical area of Indonesia. The availability of genotype with such characteristics is in accordance with farmers’ preference and also important to minimize yield losses.

“…De Godoi dan Pinheiro (2009) menyarankan seleksi ketahanan terhadap kompleks hama pengisap polong menggunakan karakter kerusakan polong, khususnya pada kedelai generasi F2 hingga F4, sedangkan pada populasi lanjut disarankan seleksi dengan menggunakan karakter tusukan pada biji. Skrining ketahanan terhadap 10 genotipe kedelai yang dilakukan oleh Krisnawati et al (2016) dengan menggunakan intensitas kerusakan biji berhasil mengelompokkannya menjadi peka, moderat dan tahan terhadap hama kepik coklat. Bayu et al (2017) menilai ketahanan 16 genotipe di lapang berdasarkan intensitas kerusakan polong dan biji, dan berhasil memperoleh tiga genotipe kedelai tergolong agak tahan terhadap kompleks hama pengisap polong.…”

“…Perilaku karakter jumlah biji per tanaman adalah mirip dengan uji dengan pilihan, semakin banyak jumlah biji akan meningkatkan intensitas kerusakan biji oleh hama kepik coklat. Krisnawati et al (2016) menyampaikan bahwa jumlah polong, jumlah biji dan berat biji tidak berpengaruh terhadap intensitas kerusakan polong maupun biji akibat serangan hama kepik coklat namun antara intensitas kerusakan polong dan intensitas kerusakan pada biji memiliki korelasi yang nyata positif. Perbedaan faktor penentu ketahahan kedelai terhadap hama kepik coklat ditentukan oleh tingkat ketahanan dari genotipe kedelai yang diuji.…”

The brown stink bug, Riptortus linearis, is the most dominant of soybean pod sucking pest in Indonesia. The objectivesof the study were to identify the resistance of soybean genotypes against brown stink bug and to determine the relationship ofagronomic characters with the intensity of pod and seed damages. Research was conducted at Balitkabi (Malang, Indonesia)from April to August 2018. Thirteen genotypes were assessed for their resistance to brown stink bug under choice and nochoicetests. A randomized block design was carry out with three replicates. The number of punctures on seed, seed and poddamages intensity on no-choice test was higher than those under choice test. Under choice test, the pod damage ranged from19.40-41.68% (average of 29.51%), and the seed damage ranged from 19.31-39.90% (average of 26.80%). Under no-choicetest, the pod damage ranged from 25.77-43.58% (average of 37.41%), and the seed damage ranged from 21.30-58.29%(average of 34.27%). The 11AB and 19BE showed consistently resistant based on pod and seed damage under the choicetest. Under no-choice-test, 19BE showed consistently resistant. The path analysis showed that an increase in the number ofseeds will possibility increase the number of punctures on the seed and then contribute to the increase of yield losses. The19BE which showed consistently resistant to brown stink bug was recommended to be further tested in the adaptation trialand released as superior variety.

“…Sedangkan jumlah tusukan pada biji yang terendah terdapat pada varietas Grobogan yaitu hanya 0,6 buah. Varietas Anjasmoro dan Grobogan diketahui sebagai varietas yang banyak diminati oleh petani karena hasil panennya yang tinggi dan sesuai untuk bahan baku tahu dan tempe (Krisnawati et al, 2016). Berdasarkan pengelompokan kriteria ketahanan yang mengacu pada Asadi (2009), varietas Anjasmoro dan Grobogan menunjukkan ketidakkonsistenan kriteria ketahanan antara polong terserang dan biji terserang di lapang.…”

Response of large seed size and early maturing soybean genotypes against pod sucking bugs complex. Pod sucking bugs (Hemiptera: Pentatomidae) is the most detrimental pest on soybean in Indonesia. These pest attacks caused the decreasing of quality and quantity of yield as well as decreased seed germination. The use of resistant varieties is an alternative control which is environmentally friendly. The objective of this study was to determine the response of various soybean genotypes against pod sucking complex in the field. The experiment was conducted on June to September 2015 in Pasuruan, East Java. The treatment was arranged in randomized block design, 16 treatments with three replicates. The treatment consists of 14 soybean promising lines (G 511 H/Anj//Anj///Anj-11-2, G 511 H/Anjasmoro-1-6, G 511 H/Anj//Anj///Anj-7-1, G 511 H/Anjasmoro/ /Anjasmoro-5-1, G 511 H/Argom//Argom-2-1, G 511 H/Anjasmoro-1-4, G 511 H/Anjasmoro-1-2, G 511 H/Anjasmoro//Anjasmoro-2-8, G 511 H/Arg//Arg///Arg///Arg-12-15, G 511 H/Anj// Anj///Anj-6-3, G 511 H/Arg//Arg///Arg///Arg-19-7, G 511 H/Anjasmoro-1-7, G 511 H/Anj//Anj///Anj////Anjs-6-7, G 511 H/Anjasmoro-1-4-2), and two varieties (Anjasmoro and Grobogan). The results showed that the differences in soybean genotypes significantly influence the intensity of damaged pod and seed caused by pod sucking bugs. The intensity of damaged pod was 29.8-64.0% per plant. The intensity of damaged seed was 13.2-63.9% per plant. The number of puncture was 1.2-1.6 punctures per pod and 0.6-2.7 punctures per seed. Based on the intensity of damaged pod and seed, genotipe G 511 H/Anjasmoro//Anjasmoro-2-8, G 511 H/Anjasmoro-1-2, and G 511 H/Anjasmoro-1-6 were indicated consistently as moderately resistance against pod sucking complex. Those three genotypes could be use as a source of genes to improve the resistance of soybean against pod sucking bug.Key words: damage intensity, morphological characters, pod sucking bug, soybean ABSTRAKRespon genotipe kedelai biji besar dan umur genjah terhadap kompleks hama pengisap polong.
