Caracterização morfológica de germoplasma de alho por análises multivariada componentes principais e variáveis canônicas

Abstract: O Banco Ativo de Germoplasma (BAG) de alho, mantido pela Embrapa Hortaliças, possui 89 acessos representativos da diversidade genética da cultura no país. A presença de genótipos duplicados na coleção onera os custos de manutenção e dificulta a avaliação agronômica dos materiais. A identificação de duplicatas no BAG de alho foi feita com a utilização de 27 variáveis de caracteres morfológicos. Essa metodologia possibilitou a diferenciação de treze grupos de genótipos através de análise multivariada. As variáve… Show more

“…This indicates that the dissimilarity measure in each location did not represent the same distribution in the accessions, suggesting that clones varied according to the environment, probably due to an interaction between genotype and environment. Menezes Sobrinho et al (1999) stated that climatic conditions play a major role in garlic yield, because the differential action of genes in different climatic conditions, for example, the photoperiod and temperature are the major influence on bulbification and hence the productivity and final economic result of the culture (Souza and Macêdo, 2009).…”

“…Clustering analysis has been used to facilitate the visual interpretation of genetic diversity in plants. The use of these techniques has been extensively reported in scientific studies on several crop species such as cassava (Nick et al, 2008;Campos et al, 2010), capsicum (Sudré et al, 2006;Bento et al, 2007;Aklilu et al, 2016), commom bean (Chiorato et al, 2005;Legesse et al, 2013), sugarcane (Sanghera et al, 2015), maize (Teodoro et al, 2015), onion (Buzar et al, 2007;Singh et al, 2013), açai palm , Brazilian turmeric (Sigrist et al, 2011), and garlic (Menezes Sobrinho et al, 1999;García Lampasona et al, 2003;Mota et al, 2006;Panthee et al, 2006;Zahedi et al, 2007;Viana et al, 2016), among others.…”
