“…Average heritability between progenies (h 2 mp ) was 0.83; 0.48 in individual plants; and 0.44 within progenies. These values are close to those obtained for Eucalyptus grandis progenies evaluated in the field by Silva et al (2013) and Mori et al (2004). The additive individual coefficient of genetic variation (CV gi 25.46%) was greater than the genetic variation between progenies (CV gp 12.73%) for rust resistance.…”

This study assessed the genetic variability in open-pollinated progenies of Eucalyptus urophylla for resistance to rust (Puccinia psidii). The progeny trial was conducted on a statistical randomized block design with 20 progenies, five plants per plot, and nine replications. Analysis of variance showed high genetic variability for the studied trait, with potential for selection gains. The genetic variability of this population provides support to conduct a breeding program with superior individuals for rust resistance, allowing low costs and minimizing the yield losses on eucalyptus plantations.

“…The impact of P. psidii on plantation grown Eucalyptus species has been shown in several previous studies (Tommerup et al 2003, Graça et al 2011, Silva et al 2013). More recently, a number of studies have shown the broad host range of the pathogen on other Myrtaceae and the fungus has been described as a significant threat to native ecosystems in Australia (Morin et al 2012).…”

The Myrtle rust pathogen, Puccinia psidii, discovered in Africa

et al. 2013

Puccinia psidii, the cause of a disease today commonly referred to as Myrtle rust, is considered a high priority quarantine threat globally. It has a wide host range in the Myrtaceae and it is feared that it may result in significant damage to native ecosystems where these plants occur. The fungus is also of considerable concern to plantation forestry industries that propagate Australian Eucalyptus species. In May 2013, symptoms of a rust disease resembling those of P. psidii were observed on an ornamental Myrtaceous shrub in a garden in South Africa. The fungus was identified based on DNA sequence data of the ITS and 5.8S nrRNA gene regions and here we report, for the first time, the presence of P. psidii in Africa.

“…This method has been applied for several species such as eucalyptus (Silva et al, 2013), cotton (Farias et al, 2016), rubber tree , and strawberry (Costa et al, 2015). However, few types of research have reported the use of this method in Jatropha breeding (Borges et al, 2014).…”

ABSTRACT. The objectives of this study were to estimate the genetic parameters for Jatropha full-sib families and to select superior genotypes based on grain yield, adaptability, and stability simultaneously to be used for cloning and crossings. Grain yield was evaluated in thirteen full-sib families in a randomized block design for 5 years. The harmonic mean of the relative performance of genotypic values and reaction norm were performed to estimate the adaptability and stability, and sequentially the 30 superior individual plants were selected based on the predicted additive genotypic value for the last crop season. Families 4, 8, and 9 may be used to several regions of Brazil since they have high genotypic adaptability and stability. Individuals belonging to families 9, 8, 2, 1, 6, and 5 should be used for cloning or crossing to obtain the next-generation individuals, and consequently to continue the Jatropha breeding.
