“…Biudes et al (2009) described the difference in performance between genotypes cultivated at the same site, as well as significant interactions with other production factors, such as environment (site, year, and sowing season) and management. These authors reported that the cultivation environment, as well as its interaction with management and genotype, may have influenced culture growth and development and consequently established the production potential, according to whether they were subjected to better or worse climate conditions during the phenological cycle of the plants.…”

The application of nitrogen (N) at the appropriate time can be effective for crop productivity, changing the grain yield by increasing yield components. Thus, new alternatives that enable a better application of N fertilizer are sought. The aim of this study was to evaluate the components of yield and productivity of wheat cultivated with different doses of N sidedressing and molybdenum (Mo) via leaf application, using two cultivars, CD 150 and Quartzo. The experiment was conducted in the crop years of 2013 and 2014. The experiment used a randomized, factorial 4 x 4 block design, with four replicates. Four doses of N sidedressing in the form of urea were applied (0, 30, 60, and 90 kg ha -1 ) during tillering. In the same period, leaf molybdic fertilizer was applied, using four dosages of Mo in the form of potassium molybdate (0, 20, 40, and 60 g ha -1 ). Grain number per ear (GNPE), 1,000-grain mass (TGM), hectoliter weight (HW), and grain productivity (PROD) were evaluated. N fertilizer sidedressing did not promote the yield components of either of the wheat cultivars, although the GNPE of the Quartzo cultivar increased with increasing N doses in both crop years. The increase in N fertilizer increased the PROD of both wheat cultivars. The foliar application of Mo did not promote the yield components or wheat PROD of either cultivar. The HW was influenced by N and Mo rates, and was reduced in the absence of either of these fertilizer elements, indicating that the two nutrients were dependent on each other.

“…The activity of these enzyme is highly dependent on Mo (BULL, 1993). Thus, Mo plays a fundamental role in the incorporation of N into the plant, acting as a cofactor of enzymes responsible for N assimilation (MARTENS; WESTERMANN, 1991).…”

“…Some models for analysis of adaptability and stability allow breeder to perceive the behavior of each genotype in favorable and unfavorable environments. They provide breeders necessary information to select the best genotype for each environment or a genotype that is proper in both environments (Biudes et al, 2009;Caierão et al, 2006;Silva et al, 2011).…”

“…O método proposto por Lin e Binns (1988), com as modificações propostas por Carneiro (1998), tem sido constantemente utilizado visando identificar genótipos de trigo com adaptabilidade e estabilidade para produção de grãos em ambientes favoráveis e desfavoráveis (Amorin et al, 2006;Biudes et al, 2009). Felício et al (2001) demonstraram que linhagens de trigo e triticale cultivadas em Mococa, no período de 1996 a 1999, tiveram diferentes padrões de resposta quando avaliadas no mesmo local, em ambientes favorá-veis (irrigação por aspersão) e desfavoráveis (várzea irrigada por inundação).…”

ResumoO objetivo desse estudo foi avaliar a adaptabilidade e estabilidade de 18 linhagens e duas cultivares de trigo quanto à produção de grãos, altura de plantas, tolerância ao alumínio (Al 3+ , revelou adaptação a ambientes desfavoráveis e maior número de espiguetas por espiga. As linhagens exibiram porte semianão com exceção da linhagem 3 (porte anão). Foram identificados genótipos superiores para resistência à ferrugem-da-folha (linhagem 12), número de espiguetas e de grãos por espiga (linhagem 15), comprimento de espigas (linhagens 5 e 8) e número de grãos por espigueta (linhagem 18). Houve tendência de os genótipos mais produtivos ficarem com porte semianão mais alto e grãos mais pesados em solo ácido e corrigido. Os genótipos mais tolerantes na presença de 2 a 6 mg L -1 de Al 3+, em solução nutritiva, foram os mais produtivos em solo ácido.Palavras-chave: Triticum aestivum L., produção de grãos, adaptabilidade e estabilidade, tolerância à toxicidade ao alumínio. Agronomic behavior of wheat inbred lines in different environments in southwest of Sao Paulo State AbstractThe objective of this study was to evaluate the adaptability and stability of 18 wheat inbred lines and two wheat cultivars (control) to grain yield, plant height, tolerance to aluminum and other characteristics in experiments carried out in acid soil and limed soil conditions, in 2006 , showed high adaptability and stability to grain yield, heavy grains and resistance to lodging. The cultivar IAC-370 and the line 6, tolerant to 4 and 8 mg L -1 de Al 3+ , were adapted to favorable environments. The line 20, tolerant to 10 mg L -1 de Al 3+, was adapted to unfavorable environments and showed good performance for number of spikelets per spike. All lines showed semi-dwarf plant, except the line 3 (dwarf). Superior genotypes were identified to leaf rust resistance (line 12), number of spikelets per spike and grains per spike (line 15), head length (lines 5 and 8) and grains per spikelet (line 18). The most productive genotypes tend to show taller semi-dwarf plant types and heavier grains in acid soil and limed soil condition. The most tolerant genotypes to 2 and 6 mg L -1 de Al 3+ in nutrient solution were the most productive in acid soil.
