Inheritance of resistance to anthracnose stalk rot (Colletotrichum graminicola) in tropical maize inbred lines

Abstract

-Generation means was used to study the mode of inheritance of resistance to

Genetic resistance of maize inbred lines to anthracnose leaf blight

“…The coefficients of variation for the three experiments were of low magnitude, with range of 6.26 to 15.96% (Table 2). These values are considered suitable for field trials involving the pathogen x host interaction, and are close to those obtained by other researchers in the same pathosystem (Coêlho et al 2001, Rezende et al 2004, Matiello et al 2012.…”

Heterosis and path analysis for grain yield and chocolate spot disease resistance in faba bean (Vicia faba L.)

“…This could be due to ILB-4726, ILB-938, BPL-710 and Gebelcho (its pedigree comprises ILB-4726) which are genetically close inbred lines. Matiello et al (2012) and Lim and White (1978) reported similar results of estimates of heterosis for maize anthracnose disease and Colletotrichum graminicola resistance in maize, respectively. Path analysis helps in measuring the direct effect of each trait as well as its indirect effect through other characters contributing to yield.…”

Identification of sources of resistance to anthracnose stalk rot in maize

“…(2014), there are different races, pathotypes, and haplotypes of C. graminicola in maize that are spread across the regions of Brazil. In general, the strains tended to show the same reaction as that obtained in the first F L150, L151, L152, L153, L154, L155, L156, L157, L158, L159, L160, L161, L162, L163, L164, L165, L166, L167, L168, L169 G L170, L171, L172, L173, L174, L175, L176, L177, L178, L179, L180, L181, L182, L183, L184, L185, L186, L187, L188, L189, L190, L191, L192, L193, L194, L195, L196, L197, L198, L199, L200 H L201, L202, L203, L204, L205, L206, L207, L208, L209, L210, L211, L212, L213, L214, L215, L216, L217, L218, L219, L220, L221, L222, L223, L224, L225, L226, L227, L228, L229, L230, L231, L232, L233, The evaluation method adopted in the present study was efficient to classify the lines to form different resistance categories to anthracnose stalk rot, as done in many reports (CARSON & HOOKER, 1981;BADU-APRAKU et al, 1987;TOMAN & WHITE, 1993;COTA et al, 2010;MATIELLO et al, 2012;COSTA at al., 2014).…”

“…Resistant cultivars carry genes with resistance to stalk rot infection, which are transferred via a quantitative inheritance mode, with the predominance of an additive genetic effect (CARSON & HOOKER, 1981;BADU-APRAKU et al, 1987;TOMAN & WHITE, 1993;BERGSTROM & NICHOLSON, 1999;PALAVERSIC et al, 2009;MATIELLO et al, 2012). Maize genotypes showing different levels of anthracnose stalk rot resistance have been described in germplasm banks; examples of such genotypes are the following: MP305, DE811ASR (JUNG et al, 1994, BROGLIE et al, 2006FREY et al, 2011);DW1035 (TOMAM & WHITE, 1993; A556, A638, Oh43, R177 (CARSON & HOOKER, 1981); RD6502 (BADU-APRAKU et al, 1987);Bc19064 (PALAVERSIC et al, 2009);CML52 (CHUNG et al, 2011);Das2, Das64 (MATIELLO et al, 2012); H8664 (MATIELLO et al, 2013); 2B710 (GARDINGO, 2008;COSTA et al, 2010b;COTA et al, 2010;CARVALHO et al, 2013).…”
