“…Guava tree cultivation has been expanding in the state of Rio de Janeiro, especially in the north and northwest regions, as it presents conditions favorable to its cultivation. Under this scenario, the Universidade Estadual do Norte Fluminense Darcy Ribeiro (UENF) has been developing a genetic breeding program of guava (P. guajava L.) over the last nine years, achieving promising results (Pessanha et al, 2011;Campos et al, 2013;Oliveira et al, 2014;Campos et al, 2016;Quintal et al, 2017a, b;Gomes et al, 2017). This study demonstrates that obtaining inbred families is a feasible way of forming superior populations.…”

The purpose of this study was to conduct selection, genetic parameter estimation, and prediction of genetic values for 18 S 1 families of guava trees using mixed model methodology and simultaneous selection of traits by means of the additive selection index, multiplicative selection index, and mean rank adapted from Mulamba. All families analyzed were obtained by means of self-fertilization of superior genotypes (full siblings) from the genetic breeding program of guava trees at the Universidade Estadual do Norte Fluminense. An experimental randomized block design with 18 S 1 families, three replicates, and ten plants per plot was used. A total of 540 genotypes (individual plants) of guava tree were evaluated. Genetic parameter estimation and selection of the best genotypes based on the genetic value were performed using the statistical procedure, from the Selegen-REML/BLUP program. The analyses of the additive selection index, multiplicative selection index, and the sum of rank adapted from Mulamba were also performed under the Selegen program. During the evaluation by the individual BLUPs, families 1, 12, 4, 6, and 8 contributed to most of the genotypes selected for the traits under evaluation, suggesting their significant potential to generate high quality and high yield genotypes. In the selection indexes via mixed models, the multiplicative index showed higher values for genetic gains (74 %), followed by the mean rank index adapted from Mulamba (19 %), and the additive index (2 %).

“…were used ( Table 1). The Paluma cultivar (Psidium guajava), which is a known susceptible cultivar to M. enterolobii, was used to evaluate the inoculum quality and to compare the results (GOMES et al, 2017). The experiment was conducted in a completely randomized design with eight replications for each accession.…”

“…This nematode is the main cause of losses in guava crops, limiting guava production in Brazil (PEREIRA et al, 2016). In addition, M. enterolobii infection is associated with soil fungi (GOMES et al, 2011), leading to a synergistic interaction that causes even greater damage to crops (GOMES et al, 2017;CASTRO et al, 2017).…”

Reaction of Psidium Spp. Accessions to Different Levels of Inoculation With Meloidogyne Enterolobii

Meloidogyne enterolobii associated with Fusarium solani causes the guava decay, which is the main factor of yield loss in guava crops and limits guava production in Brazil. Therefore, searching for guava genotypes (Psidium spp.) with resistance to M. enterolobii is important to control this root-knot nematode. The objective of the present work was to evaluate the reaction of Psidium spp. accessions from the Germplasm Bank of the Bahia State University (UNEB) to different levels of inoculation with M. enterolobii. Guava seedlings were inoculated with 600, 1,600, and 2,000 eggs + J2 second stage juveniles of M. enterolobii and the root fresh weight, total number of eggs (TNE), and reproduction factor (RF) were evaluated. The results were subjected to ANOVA and means were clustered using the Scott-Knott test at 5% probability. The diversity of accessions was estimated using the Tocher's clustering and UPGMA methods. The nematode RF reduced in some accessions with increasing inoculation levels of the nematode. However, the RF increased in some accessions with high levels of inoculation. Plants of the Y50 accession were immune or resistant to M. enterolobii, indicating variability of reaction of plants to the nematode within the Psidium genus. The resistance of Psidium accessions to M. enterolobii needs to be measured with different inoculation levels to verify the existence of false-positive results, since the evaluated accessions, including the Paluma cultivar, presented distinct reactions regarding RF in the three levels of inoculation used.

“…Besides, they correct the data for the environmental effects and can predict the genetic values, with accuracy and free from bias, which maximizes the genetic gain with selection (Resende, 2002). This procedure has been applied in several crops, especially perennial and fruit crops, such as coffee (Carias et al, 2016), rubber tree (Kalil et al, 2000), eucalyptus (Rocha et al, 2006), cupuaçu (Alves e Resende, 2008), açaí (Teixeira et al, 2012), sugarcane (Lopes et al, 2014), guava (Gomes et al, 2017) and papaya (Vivas et al, 2014).…”

Passion fruit tree belongs to the family Passifloraceae. The genus Passiflora is considered of great economic value, and the main species cultivated is Passiflora edulis Sims. Brazil is the largest world producer of passion fruit, with annual production of around 823 thousand tons. In order to meet the demand for fruits from both domestic and international markets, as well as from the fresh consumption market and industry, the genetic breeding of this species has proved to be the major connection between farmers and the consumer market. Therefore, the Universidade Estadual do Norte Fluminense Darcy Ribeiro has been developing a passion fruit breeding program since 2002 and has recently launched a new variety-UENF Rio Dourado-which is already available to farmers. Aiming to overcome all obstacles for cultivation, the passion fruit genetic breeding program carried out by the UENF seeks to obtain the genetic progress of the crop and provide new cultivars even more productive and more resistant to the main pathogens of this species. Thus, this work aims to carry out a survey on the breeding of the crop and report future prospects made possible by the introduction of new techniques into the sour passion fruit breeding program.
