“…Pinnow et al (2013) also verified a positive effect of N fertilization on dough gluten strength and wet gluten concentration from harvested grains of a Brazilian wheat genotype (BRS Pardela). On the other hand, while investigating several Brazilian wheat genotypes, Schmidt et al (2009) and Bassoi and Foloni (2012) did not observe any increase in dough gluten strength due to N fertilization, even with an increase in grain protein concentration. In this context, the increase of dough gluten strength due to increased grain protein concentration promoted by N fertilization, up to the measure that it modifies the commercial classification of wheat, is still uncertain (RCBPTT, 2016).…”

The quality of grains and flour can be influenced by genetics, crop management, and environment. The objective of this study was to evaluate the technological quality of wheat grains and flour influenced by the interaction among genotype, nitrogen (N) fertilization and weather conditions in different regions of wheat crop adaptation in southern Brazil, aiming to support farmers and the bakery industry sector in their decision-making processes. The experiment was carried out in three environments (Londrina in rainfed and irrigated conditions; and Ponta Grossa in rainfed) in a randomized block design with a 10 × 2 factorial scheme. Ten wheat genotypes (BRS Sanhaço, BRS Graúna, BRS Gaivota, BRS Gralha-Azul, TBIO Sinuelo, TBIO Mestre, TBIO Sossego, TBIO Sintonia, TBIO Toruk, and Quartzo) and two N rates (40 and 120 kg ha-1) were assessed. The following technological quality analyses were performed in grains or flour: hectoliter weight, thousand-kernel weight, falling number, grain protein concentration, experimental flour extraction (i.e. flour yield), wet gluten concentration, and alveography. Increasing N rates from 40 to 120 kg ha-1 enhanced the concentrations of grain protein and wet gluten. However, it did not influence dough gluten strength and the commercial classification of the flour. Nitrogen fertilization also influenced the flour yield, dough tenacity and elasticity index, depending on the genotype × environment interaction. Environments with higher temperatures favored the flour yield and wet gluten concentration, while lower temperatures increased thousand-kernel weight and falling number. Water deficit increased the dough extensibility and grain protein concentration, whereas higher water availability favored the falling number, dough tenacity, and tenacity/extensibility ratio. Therefore, these outcomes are important drivers for farmers when choosing specific wheat genotypes for the environmental conditions of their farms, when they intend to meet the industrial requirements of mills and food companies that use wheat flour.

Resumo -O objetivo deste trabalho foi identificar as melhores épocas de semeadura e avaliar a adaptabilidade e a estabilidade de cultivares de trigo, em duas regiões tritícolas do Paraná. Avaliou-se a produtividade de grãos de sete cultivares, em Guarapuava, e de nove, em Palotina, em quatro épocas de semeadura, em 2006, 2007 e 2008. Utilizou-se o delineamento experimental de blocos ao acaso, com quatro repetições em Guarapuava, e três em Palotina. Foram utilizadas a metodologia REML/BLUP e a dos efeitos principais dos genótipos e da interação genótipo x ambiente (GGE biplot) para a avaliação da adaptabilidade e da estabilidade das cultivares, e o método AMMI para a identificação das melhores épocas de semeadura. Semeaduras em julho, em Guarapuava, e em abril, em Palotina, maximizam a produtividade de grãos. As cultivares Safira, em Guarapuava, e CD 113, em Palotina, são estáveis, amplamente adaptadas e apresentam alta produtividade de grãos.Termos para indexação: Triticum aestivum, AMMI, GGE biplot, interação genótipo x ambiente, REML/BLUP. Adaptability and stability of wheat cultivars at different sowing dates in the state of Paraná, BrazilAbstract -The objective of this work was to identify the best sowing dates and to evaluate the adaptability and stability of wheat cultivars in two wheat growing regions of the state of Paraná, Brazil. Seven cultivars were evaluated at Guarapuava and nine at Palotina as to grain yield, at four sowing seasons, in 2006, 2007 and 2008. The experimental design was a randomized complete block design, with four and three replicates, for Guarapuava and Palotina, respectively. The methodologies REML/BLUP and genotype main effect and genotype x environment interaction (GGE biplot) were used for adaptability and stability analysis, and the AMMI model was used to identify the best sowing dates. Sowing in July, at Guarapuava, and in April, at Palotina, maximized grain yield. The cultivars Safira, at Guarapuava, and CD 113, at Palotina, are stable, highly adapted and show high grain yield.Index terms: Triticum aestivum, AMMI, GGE biplot, genotype x environment interaction, REML/BLUP. IntroduçãoO trigo (Triticum aestivum L.) é o cereal de maior importância econômica mundial, com mais de 600 milhões de toneladas produzidas anualmente. O Brasil contribui com cerca de seis milhões de toneladas, com destaque para a região Sul, responsável por 90% da produção nacional (Companhia Nacional de Abastecimento, 2010), e para o estado do Paraná, o maior produtor do país.A expressão do potencial de produtividade de grãos depende de fatores genéticos e ambientais, bem como da interação entre ambos, o que resulta em expressivas diferenças no desempenho das cultivares quando cultivadas em diferentes condições ambientais (Yan & Holland, 2010). O termo ambiente (época de semeadura, ano e práticas culturais) pode ser definido como o resultado dos componentes biofísicos que influenciam o desenvolvimento e o crescimento das plantas.O potencial de produtividade de grãos pode ser maximizado pela escolha adequa...

The potential yield of wheat is mainly determined by temperature, solar radiation and the photothermal quotient. The objective of this study was to determine the temporal and spatial variability of the photothermal quotient and the frost risk to identify suitable sowing dates for wheat in Parana State, Brazil. The results showed that the photothermal quotient has greater spatial variability than temporal variability. The sowing date affects crop conditions that can in turn affect yield. However, the photothermal quotient and frost risk fluctuate differently in different Value for Cultivation and Use (VCU) regions. The regions VCU 1 and VCU 2 showed greater temporal variability of the photothermal quotient. The photothermal quotient ranged from 1.5 to 2.0 MJ m -2 day ºC in VCU 1, from 1.1 to 1.5 MJ m -2 day ºC in VCU 2 and from 1.0 to 1.2 MJ m -2 day ºC in VCU 3. Sowing performed in June provided the greatest photothermal quotient in all VCU regions. However, June sowing increased the frost risk in VCU 1. Thus, the sowing date can be used as a management tool for the attainment of higher yield in wheat.Uso do quociente fototermal e risco de geadas na identificação de época de semeadura adequadas em trigo RESUMO. O potencial de rendimento de grãos em trigo varia, principalmente, em função da temperatura, radiação solar e do quociente fototermal. O objetivo foi estudar a variabilidade temporal e espacial do quociente fototermal (QF) e o risco de geadas visando identificar épocas de semeadura para a cultura do trigo que propicie o maior rendimento de grãos no estado do Paraná, Brasil. Os resultados demonstraram que há maior variabilidade do QF no espaço em relação ao tempo. A época de semeadura afeta as condições de crescimento da cultura, podendo incrementar o rendimento de grãos. Entretanto, o QF e o risco de geadas variam conforme a região de VCU. As regiões de VCU 1 e 2 apresentaram a maior variabilidade temporal do QF. A variação temporal para a região de VCU 1 ficou entre 1,5 a 2,0 MJ m -2 dia ºC (VCU 1), 1,1 a 1,5 MJ m -2 dia ºC (VCU 2) e 1,0 a 1,2 MJ m -2 dia ºC. Em todas regiões de VCU, semeaduras realizadas no mês de junho proporcionam o maior valor de QF. Entretanto, há elevado risco de geadas na região de VCU 1 quando a semeadura ocorre em junho. Assim, a época de semeadura pode ser uma importante ferramenta no manejo para alto rendimento de grãos em trigo.Palavras-chave: Triticum aestivum (L.), potencial de rendimento, radiação solar. 100Silva et al.
