Herança de caracteres morfológicos de grãos primários em aveia

Abstract: A produção de cultivares com grãos de superior qualidade física tem adquirido importância, especialmente com a crescente globalização dos mercados sul-americanos. A fim de definir as melhores estratégias de ação para o melhoramento dessas características, é fundamental o estudo das suas bases genéticas e, até o momento, não existe registro de trabalhos desta natureza com germoplasma brasileiro de aveia. Este trabalho foi realizado com o objetivo de estimar o modo de herança e herdabilidade dos caracteres área,… Show more

“…This allows an improved efficiency IC Nava et al in the selection of well-adapted genotypes with high yield potential. Several studies investigated the genetic control of important oat traits, such as partial leaf rust resistance (Martinelli et al 2009), photoperiod sensitivity and flowering (Locatelli et al 2008), tolerance to aluminum toxicity (Oliveira et al 2005, Nava et al 2006, morphology of primary grain (Cabral et al 2001), plant height (Mariot et al 1999), and panicle type (Bertagnolli and Federizzi 1994).…”

“…Many soybean researches have been done on broad and narrow sense heritability estimates (AZEVEDO FILHO et al, 1998;TOLEDO et al, 2000;FARIAS NETO and VELLO, 2001;ROSSMAN, 2001;REIS et al, 2002), though few of them have been done using parentoffspring regression, among which is an oat and a soybean study (CABRAL et al, 2001;MUNIZ et al, 2002).…”

“…The average degree of dominance was 1.17. Cabral et al (2001Cabral et al ( , 2002 did not verify significant transgressive segregation in the generations of the crossings among four oat genotypes, since the genes that control certain characters are not distributed complementarily among the parents, which allows of the accumulation of favorable or unfavorable genes in the progenies. Variance-based, 5.37 genes controlling antixenosis-resistance in BGH-1497 were estimated, which indicates polygene inheritance.…”
