Desempenho agronômico de novos híbridos de milho-pipoca no Noroeste do Estado do Paraná

Abstract: RESUMO. Em milho, variações de desempenho agronômico são comuns em ambientes distintos, havendo resposta ainda mais diferenciada em híbridos simples. Este trabalho teve como objetivo avaliar o desempenho de novos híbridos simples de milho-pipoca, desenvolvidos pelo Programa de Melhoramento da Universidade Estadual de Maringá, no noroeste do Paraná. Para isso, avaliaram-se as características agronômicas de rendimento de grãos, capacidade de expansão, altura de planta, altura de espiga, resistência à ferrugem po… Show more

“…The overall mean yield was 1533.43 kg/ ha, which is considered low for experimental popcorn hybrids. Vieira et al (2009) observed a mean grain yield of 2429.4 kg ha and reported that these values were in agreement with those obtained by Scapim et al (2002).…”

“…The overall mean popping expansion was 25.70 mL/g, which was very close to the 25.86 mL/g value reported by Vieira et al (2009). Galvão et al (2000) state that popping expansion rates between 21 and 26 mL/g are good, and rates higher than 26 are considered excellent.…”

“…Associar elevados rendimentos a boa capacidade de expansão não é uma tarefa simples; a correlação negativa entre essas características (PACHECO et al, 1998;DAROS et al, 2004b;VIEIRA et al, 2009b) dificulta a eficiência do trabalho do melhorista, sobretudo quando se utiliza seleção truncada RANGEL et al, 2007;SANTOS et al, 2007;VIEIRA et al, 2009a). Para contornar esse inconveniente é necessário recorrer ao uso dos índices de seleção, cuja pujança estatística sobrepõe a correlação negativa e permite a seleção de progênies produtivas e com elevada qualidade da pipocamento dos grãos em programas de seleção recorrente.…”

“…Vieira et al (2009) Considerably differing grain yields of the hybrid Zélia, from Pioneer, were observed in studies in the States of São Paulo (SAWAZAKI et al, 2000) and Paraná (PINTO et al, 2007), with estimates of 3691.00 and 1.096.00 kg ha -1 , respectively.…”

“…However, intensive studies on the crop are still needed, especially on adaptability and stability, since most cultivars grown Acta Scientiarum. Agronomy Maringá, v. 32, n. 2, p. [269][270][271][272][273][274][275][276][277]2010 in Brazil come from North America (DAROS et al, 2004;FREITAS JÚNIOR et al, 2006;DANDOLINI et al, 2008;MIRANDA et al, 2008;VIEIRA et al, 2009). In addition, only few cultivars are available in the domestic market, for the small producer as well as for large-scale production (SANTOS et al, 2007;RANGEL et al, 2008;SILVA et al, 2009).…”
