The objective of this work was to identify by biometric analyses the most stable soybean parents, with higher oil or protein contents, cultivated at different seasons and locations of the state of Minas Gerais, Brazil. Forty-nine genotypes were evaluated in the municipalities of Viçosa, Visconde do Rio Branco, and São Gotardo, in the state of Minas Gerais, from 2009 to 2011. Protein and oil contents were analyzed by infrared spectrometry using a FT-NIR analyzer. The effects of genotype, environment, and genotype x environment interaction were significant. The BARC-8 soybean genotype is the best parent to increase protein contents in the progenies, followed by BR 8014887 and CS 3032PTA276-3-4. Selection for high oil content is more efficient when the crossings involve the Suprema, CD 01RR8384, and A7002 genotypes, which show high mean phenotypic values, wide adaptability, and greater stability to environmental variation.

 RESUMO – O objetivo deste trabalho foi avaliar o desempenho agronômico e estabilidade fenotípica de híbridos topcrosses de milho oriundos do cruzamento com uma linhagem elite (testador), em quatro ambientes (Guarapuava- PR, Candói-PR, Guarda-Mor-MG e Paracatu-MG), utilizando os métodos Annicchiarico e AMMI para selecionar linhagens com elevado potencial genético. Foram avaliados 88 híbridos topcrosses e 12 híbridos comerciais (2B688, AG9010, AS1575, DKB390, GNZ2500, GNZ8132, GNZ9501, GNZ9505, P30F53, P30R50, P30F35 e Penta). O delineamento utilizado foi o látice triplo 10x10 e foram avaliadas as características agronômicas altura de planta (AP), altura de espiga (AE) e estabilidade produtiva de grãos (PG). Observou-se efeito significativo para genótipo, ambiente e interação genótipo x ambiente para a PG. A média de produtividade dos genótipos foi maior em Paracatu-MG (11.100 kg ha-1) que em Candói (9.654 kg ha-1), Guarapuava (9.456 kg ha-1) e Guarda-Mor (9.446 kg ha-1). Com base nos resultados de PG e estabilidade utilizando os métodos Annicchiarico e AMMI, o híbrido topcross HTC 136 mostrou ser o melhor para seguir no programa de melhoramento no processo de endogamia.Palavras-chave: Annicchiarico, AMMI, interação genótipo x ambiente, testador, Zea mayz L. AGRONOMIC PERFORMANCE AND STABILITY OF MAIZE TOPCROSSES IN MINAS GERAIS AND PARANÁ ABSTRACT – The objective of this study was to evaluate the agronomic performance and phenotype stability of top cross maize hybrids originated by crossing with an elite line (tester), in four environments (Guarapuava-PR, Candói- PR, Guarda-Mor-MG and Paracatu-MG), using the methods Annicchiarico and AMMI to select lines with high genetic potential. Thus, 88 top cross hybrids and 12 commercial hybrids (2B688, AG9010, AS1575, DKB390, GNZ2500, GNZ8132, GNZ9501, GNZ9505, P30F53, P30R50, P30F35 and Penta) were evaluated. The 10x10 triple lattice design was used evaluating the agronomic characteristics plant height (PH), ear height (EH) and yield stability of grain (YG). Significant differences were observed for genotype, environment and genotype x environment interaction for YG. The average productivity of the genotypes was superior in Paracatu-MG (11,100 kg ha-1) compared to Candói (9,654 kg ha-1), Guarapuava (9,456 kg ha-1) and Guarda-Mor (9,446 kg ha-1). The data on YG and stability using Annicchiarico and AMMI methods showed that the top cross hybrid HTC 136 is suitable to continue in the inbreeding process of the breeding program.Keywords: Annicchiarico, AMMI, genotype-environment interaction, tester, Zea mayz L.

Abstract: The objective of this work was to evaluate corn cultivars grown in the state of Amazonas, Brazil, which simultaneously show high grain yield, adaptability, and stability. The trials were carried out in seven environments in the state of Amazonas, in a randomized complete block design, with two replicates. The grain yield of 30 corn cultivars was evaluated in four growing seasons, from 2011/2012 to 2014/2015. The genetic parameters were estimated by the REML/Blup methodology. The selection for adaptability and stability was based on the predicted genetic value and on the harmonic mean of the relative performance of the genetic values. Despite the existence of genotype x environment interaction, cultivars with high adaptability and stability were identified. Iranduba - lowland, in 2011/2012 and 2014/2015 - and Rio Preto da Eva - upland, in 2012/2013 - stood out as favorable environments, while Iranduba - upland, in 2011/2012 and 2012/2013 - and Manaus - upland, in 2012/2013 and 2013/2014 - were classified as unfavorable environments. The single-cross hybrid BRS 1055 showed productive superiority and high stability in this region. The Sint 10771, Sint 10781, and Sint 10699 synthetic varieties showed high adaptability. BRS Caimbé shows specific adaptability to cropping in upland environments of the state of Amazonas, Brazil.

AbstrakUji multilokasi merupakan fase yang penting dalam menyeleksi hibrida jagung yang stabil pada lingkungan yang luas dan menyeleksi hibrida superior untuk lokasi spesifik. Tujuan penelitian ini yaitu untuk mengetahui kegenjahan dan daya hasil hibrida Padjadjaran, serta menentukan interaksi genotip dengan lingkungan (G x E), stabilitas, dan adaptabilitas karakter kegenjahan hibrida Padjadjaran di tiga lokasi selama dua musim yang berbeda di Jawa Barat. Rancangan percobaan yang digunakan adalah Rancangan Acak Kelompok dengan  delapan belas perlakuan yang terdiri dari enam belas hibrida Padjadjaran dan dua kultivar cek. Percobaan dilaksanakan selama dua tahun berturut- turut yaitu tahun ke-1 (Maret sampai Juli, 2014) dan tahun ke-2 (Maret sampai Juli, 2015) di tiga lokasi di Jawa Barat, yaitu: Jatinangor - Sumedang, Lembang - Kabupaten Bandung Barat, dan Wanayasa - Kabupaten Purwakarta. Uji lanjut yang digunakan untuk mengetahui perbedaan nilai rerata kegenjahan dan daya hasil digunakan analisis Duncan Multiple Range Test (DMRT), sedangkan untuk menentukan interaksi G x E, stabilitas, dan adaptabilitas menggunakan Genotype plus Genotype x Environment (GGE) biplot. Hasil memperlihatkan bahwa analisis GGE dapat menentukan interaksi G x E, stabilitas, dan adaptabilitas jagung manis hibrida Indonesia di Jawa Barat secara akurat. Model GGE disarankan untuk dapat digunakan sebagai aplikasi analisis untuk perilisan hibrida unggul di Indonesia oleh Kementerian Pertanian.Kata Kunci: Adaptabilitas, Interaksi  G x E, kegenjahan, Stabilitas Abstract. Multi-environment testing is an important stage to select stable hybrid for broad environment and to select superior hybrid for a specific environment. To determined G x E (Genotype x Environment) interaction, stability and adaptability of Padjadjaran sweet corn in Indonesia, sixteen new Padjadjaran sweetcorn hybrids and two commercial hybrids were tested in three locations for two different seasons in West Java, Indonesia. Duncan multiple range was used to elaborate the difference between sweetcorn hybrids for short duration and yield, while Genotype plus Genotype x Environment (GGE) biplot analysis was used to determine G x E interaction, stability, and adaptability. Results showed that GGE analysis was accurately determined G x E interaction, stability, and adaptability of Indonesian sweet corn in West Java. The GGE model is suggested to implement as a tool for Ministry of Agriculture  to release superior hybrid in Indonesia.Keywords: Adaptability, G x E interaction, Short duration, Stability

Barley Genotypes

The objective of this experiment was to estimate the magnitude of genotype X environment interaction on grain yield and yield related traits. Twelve varieties of food barley were included in the study planted in randomized complete block design with three replications. The ANOVA of combined and individual location revealed significant differences among the food barley genotypes for grain yield and other traits. The results of ANOVA for grain yield showed highly significant (p≤0.01) differences among genotypes evaluated for grain yield at Maychew and significant (p≤0.05) differences in Korem, Alage and Mugulat. The ANOVA over locations showed a highly significant (p≤0.01) variation for the genotype effect, environment effects, genotype X environment interaction (GEI) effect and significant (p≤0.05) variation for GEI effect of yield and for most of the yield related traits of food barley genotypes. Haftysene, Yidogit, Estayish and Basso were the genotypes with relatively high mean grain yield across all locations and they are highly performing genotypes to the area. Among locations, the highest mean grain yield was recorded at Korem and it was a suited environment to all the genotypes whereas Mugulat is unfavoured one.
