Investment in silvicultural techniques is notice-ably lacking, especially in breeding programs for non-conventional wood species. Studying genotype×environment interaction (G×E) is essential to the development of breeding programs. Thus, this study aimed to estimate genetic diversity of and the efects of G×E interaction on two progeny tests of Cordia trichotoma, including the estimation of genetic gain and genetic diversity after selection. For the experiment, 30 progenies of C. trichotoma were tested at two sites with difering soil textures. Diameter at breast height (1.30 m above soil surface, dbh-cm), total height, diameter at 30 cm from the soil, frst branch height, and survival were all monitored for four years. Statistical deviance, best linear unbiased estimator, and harmonic mean of relative performance of genetic values (MHPRVG) were all calculated to predict breeding values, estimate genetic parameters, and analyze deviance. All quantifed traits varied signifcantly among progenies by soil type, with greatest variation recorded for genetic variability. Heritability of the progenies led to predictions of genetic gain, ranging from 7.73 to 15.45%, for dbh at four years of age. The calculated decrease in genetic diversity after selection showed that this parameter should be monitored in subsequent breeding cycles. G×E was low for all tests. The best-performing progenies proved most stable and best adapted to the diferent environmental conditions tested. |

Among the major constrains to banana breeding for Fusarium wilt resistance is the long period necessary for evaluations in the field and the lack of an effective method for early detection of resistant genotypes. This work aimed to establish a screening method for Fusarium wilt resistance under greenhouse conditions and to validate its reliability by challenging cultivars with different levels of resistance. In a firts step, two types of substrates (vermiculite and washed river sand) and three inoculum sources (conidial suspension from 1- week-old colonies grown in potato dextrose agar (PDA), conidial suspension produced after stress of 1-week-old colonies and Foc-colonised corn meal-sand (CMS) medium) were studied by inoculating 45-day-old plantlets of 'Silk' (AAB, susceptible) in a double-tray system. Symptoms were observed in plants grown in both substrates, but highest incidence occurred in washed river sand. Low infection rates were observed when using conidial suspension from PDA-grown colonies. By contrast, inocula from stressed colonies and CMS caused consistent symptom expression. Using washed river sand as substrate and inoculum from PDA-grown stressed colonies and/or Foc-colonised CMS, plantlets of the cultivares 'Tropical' (AAAB) and 'Thap Maeo' (AAB) (field intermediate resistance) were challenged. Plantlets of 'Silk' and 'Grande Naine' (AAA) were used as susceptible and resistant controls, respectively. While the incubation period in Silk was 13 days after inoculation (dai), in 'Tropical' and 'Thap Maeo' initial symptoms were only observed at 17 dai. No symptoms were observed in 'Grande Naine'. The disease progress evaluated based on external symptoms and rhizome discoloration scales allowed cultivars discrimination according to resistance levels. Since experiments were repeated three times with similar results, our research suggests that the method here described could be suitable for early detection of banana genotypes resistant to Fusarium wilt.
