Seleção de pré-cultivares de milho-pipoca baseado em índices não-paramétricos

Abstract: RESUMO -O presente trabalho teve como objetivo fazer uma seleção prévia de pré-cultivares de milho-pipoca para o registro no MAPA, com base em diferentes caracteres, utilizando o índice de Garcia e o de soma de classificação, priorizando-se o rendimento de grãos e capacidade de expansão. Foram avaliados 16 genótipos de milho-pipoca, sendo oito variedades de polinização aberta (BRS Angela, UFVM2 -Barão de Viçosa, Viçosa, Beija-Flor, SAM, UNB2U-C3, UNB2U-C4 e UNB2U-C5) e oito híbridos (Zelia, Jade, IAC 112, P 1 … Show more

“…Furthermore, one obtains more reliability with the GARCIA (1998) index, which in statistic tests is based on the discrimination of the averages and on the establishing of minimum acceptable levels, which becomes quite a bit more thorough in strain selection. Similar results were found by VITORAZZI et al (2013), where the GARCIA index (1998) and the MULAMBA & MOCK index (1978) were quite correlated, showing close and positive gains to popcorn.…”

“…No melhoramento do milho-pipoca, as principais características de interesse são a capacidade de expansão e o rendimento de grãos (Silva et al, 2013). Ao se comparar os índices de seleção ao RG e à CE, observa-se que, apesar da correlação negativa entre essas duas características, houve ganhos para todos os índices testados, com exceção do índice de seleção de Williams, o qual foi de 16,02%, para RG, e de -1,68% para CE (Figura 1).…”

“…In Brazil, about US$ 7.1 million were traded in sweet corn seeds, occupying approximately 50 thousand hectares in 2012 (ABCSEM, 2014). It is worth mentioning that the commercial cropping of sweet corn does not meet the current Brazilian demand (Moterle et al, 2012;Ribeiro et al, 2012;Vittorazzi et al, 2013). Sweet corn has distinct characteristics compared to common green corn (Pena et al, 2012), with reduced genetic variability available for direct use in breeding programs.…”
