A soja (Glycine max L.) é um dos produtos agrícolas mais importantes para o Brasil, além disso, é uma rica fonte de proteína e óleo para nutrição humana. A produtividade das plantas de soja pode ser severamente prejudicada pelo inseto Helicoverpa armigera, que foi oficialmente detectado, no Brasil, durante a safra 2012/2013. A principal estratégia de gerenciamento para essa praga é o controle químico e plantas Bt. No entanto, métodos menos agressivos devem ser incorporados para o manejo sustentável, como a obtenção de genótipos resistentes. Nesse sentido, o presente trabalho consiste em uma pesquisa bibliográfica sobre os estudos de melhoramento genético de soja que visem à obtenção de genótipos resistentes à H. armigera. Para tanto, foram selecionados artigos nacionais e internacionais que abordassem o tema. Conforme os dados obtidos, as cultivares BP, M4, Sahar, JK, L17, Gorgan3, PI 227687, PI 274453, PI 274454, PI 229358, PI 171451, IAC 17 e IAC 19 apresentam resistência à H. armigera e poderão ser incorporadas aos programas de melhoramento brasileiro. De modo geral, acredita-se que esta pesquisa servirá como material de referência para apoiar pesquisadores na condução de estudos futuros que visem ao melhoramento de soja.

Biological Methods

The purpose of our study was to develop biological methods to protect soybean from pests. Lepidoptera is believed to be one of the most numerous groups of insects in this crop. As a conservative estimate, 20 species of Lepidoptera were found in soybean agrocenosis; the greatest damage to Glycine max L. caused Etiella zinkinella Tr. 1832 and Helicoverpa armigera Hb. 1805. It was shown that not less than 500 m distance of crops from the main reserve of pests – robinia and the use of early ripening varieties provided the minimum loss of bean yield (no more than 0.9 – 1.9%). The use of biological preparations based on B. thuringiensis – lepidocide and bitoxybacillin allowed reducing beans and seeds damage by pests by 20-30%.

Abstract Helicoverpa armigera (Hübner) (Lepidoptera: Noctuidae) is an important pest capable of colonizing several species of cultivated plants, including soybean [Glycine max (L.) Merrill]. The primary management strategy for this insect is chemical control and adoption of Bt plants. However, alternative environmentally friendly strategies should be investigated and adopted as available for sustainable management of this insect pest. One potential underutilized method for insect control is plant resistance. The objective of this study was to categorize resistance (antixenosis and antibiosis) of 22 soybean genotypes on H. armigera in a laboratory setting. A preliminary experiment was conducted using soybean leaves and pods to determine the most promising genotypes for resistance. For each selected genotype, we collected biological parameters, leaf intake, and performed confinement tests. The genotypes PI 227687, PI 274453, PI 274454, PI 229358, PI 171451, ‘IAC 17’, and ‘IAC 19’ expressed resistance against H. armigera. Each genotype lowered larval survivorship. The genotypes PI 229358, PI 227687, PI 274453, and PI 274454 expressed resistance by prolonging larval development and reducing fifth-instar larvae weight. ‘IAC 19’ reduced leaf consumption and lowered the weight of fifth-instar larvae. Antixenosis was found in genotypes PI 227687, PI 274454, and ‘IAC 19’. These genotypes might be used in breeding programs focusing on soybean resistance to lepidopterans.

Glycine Max L

The legume seed coat is the site of sucrose unloading and the metabolism of imported ureides and synthesis of amino acids for the developing embryo. The cell types directly responsible for these functions in the seed coat are not known. We recently described a convex layer of tissue on the inside surface of the soybean (Glycine max L. Merr.) seed coat that was termed “antipit” because it was in direct opposition to the concave pit on the abaxial surface of the cotyledon. Cone cells of the antipit contained numerous hypertrophied Golgi apparatus and laminated rough endoplasmic reticulum common to actively secreting cells. The initial report by Dzikowski (1936) described the morphology of the pit and antipit in G. max and found these structures in only 68 of the 169 seed accessions examined.

Penelitian tentang pengaruh pemberian Pupuk organik cair (POC) asal limbah tumbuhan terhadap serapan hara N dan P serta produksi tanaman kedelai (Glycine max (L) Merrill) di lahan gambut telah dilaksanakan di kampus II Unisi Fakultas Pertanian Jl. Lintas Propinsi Parit 01, Desa Pulau Palas, Kecamatan Tembilahan Hulu, Kabupaten Indragiri Hilir Propinsi Riau. Dimulai dari bulan Agustus sampai bulan Oktober 2013. Tujuan dari penelitian ini untuk mendapatkan POC asal limbah tumbuhan yang terbaik untuk serapan hara N dan P serta produksi tanaman kedelai di lahan gambut. Penelitian ini menggunakan rancangan acak kelompok (RAK) faktor tunggal dengan 7 perlakuan dan 4 ulangan, 2 tanaman dijadikan sampel. Perlakuan dosis POC limbah tanaman pisang dan POC limbah sayur kol yang diberikan yaitu 0 L/Ha, 200 L/Ha, 400 L/Ha dan 600 L/Ha. Parameter pengamatan yaitu : serapan hara N dan P pada fase awal generatif, tinggi tanaman, jumlah bintil akar, polong hampa, produksi perplot, berat 100 biji dan brangkasan kering. Data pengamatan dianalisis dengan sidik ragam (ANOVA) dan dilanjutkan dengan Uji Lanjut Tukey HSD pada taraf 5%. Berdasarkan penelitian yang telah dilaksanakan dapat disimpulkan bahwa pemberian POC asal limbah tumbuhan tidak berpengaruh nyata terhadap serapan hara N dan P, tinggi tanaman, jumlah bintil akar, polong hampa, brangkasan kering tetapi berpengaruh nyata terhadap produksi perplot dan berat 100 biji.
