Yerba mate is largely used to produce drinks to human consume. In Spring the plants develop tender young leaves that could represent a new market niche in the yerba-mate industry; this period is called as ”pressafrinha” in this study. This study aimed to analyze the total and hydro soluble nutritional values of young leaves collected in the Spring season and its nutritional potential for human consumption. To r...
The estimated Harmonic Mean for Genetic Values (MHVG), Relative Performance of Genetic Values (PRVG) and the Harmonic Mean of Relative Performance of Genetic Values (MHPRVG) were used as measures to provide and facilitate the interpretation of genotypic stability and adaptability of Eucalyptus grandis W. Hill ex Maiden. The different criteria were applied as alternatives to the simulation of selection for produ...
Twenty and twenty three seed provenances of Grevillea robusta A. Cunn. were imported from Australia, in 1993 and 1994, respectively, by Embrapa Florestas. This genetic germoplasm was utilized for starting a breeding program in the states of Paraná, São Paulo and Mato Grosso do Sul. In 2002, twenty eight genotypes were selected in the Presidente Castelo Branco-PR district whose seeds were utilized for the instal...
Twenty and twenty three seed provenances of Grevillea robusta Cunn were imported from Australia, in 1993 and 1994 respectively, by Embrapa Florestas. This genetic germoplasm was utilized for starting a breeding program in the State of Paraná, São Paulo and Mato Grosso do Sul. Total surface occupied by Grevillea experiments managed by Embrapa Florestas reachs 27,13 ha, being provenance tests, embracing 11,22 ha,...
This research work was developed in order to evaluate progeny trials of Eucalyptus grandis W. Hill ex Maiden using the software SELEGEN-REML/BLUP. The best trees were identified in order to be used in seedling and clonal orchards. Fifty three half-sib progenies of three Australian provenances were tested in the municipalities of Mogi Guaçu, Boa Esperança do Sul and Caçapava, all located in the State of São Paul...
The aims of this study were to estimate the genetic parameters for 59 half-sib progenies of maté under runing for formation, and to evaluate the ecophysiological properties for four progenies (P15, P18, P41 e 47) and two controls (P61 and P62), components of one maté breeding experiment combining rovenances and progenies, established in Erechim, RS. The ecophysiological properties (stomatal onductance (gs) -...
The perennial plant selection is based on individual genetic values predicted from phenotypic observations. The more adequate the control of environmental variability, the more accurate the prediction. This paper aimed to investigate: 1) the test ability by using the significance of Snedecor F test for block effects; 2) the spatial variability within blocks by using the plot intraclass correlation coefficie...
This paper aimed to select progenies of “erva-mate” (Ilex paraguariensis St. HiI.) in Ivai - PR based on leaf weight productivity, stability and adaptability across three harvests. This can be achieved by the method MHPRVG (harmonic average of relative performance of genetic values) which is comparable with the methods by Annichiaricco and Lin & Binns. The genetic material was constituted by 25 half sib progeni...
Imbuya (Ocotea porosa Nees et Martius ex. Nees, Lauraceae) is a species under extinction of the Mixed Ombrophylous Forest, whose wood owns high economic value. The objective of this work was to discuss precocious individual genetic selection utilizying Selegen REML/BLUP software in germoplasm of Colombo, PR, Canoinhas and Caçador, SC, populations. Results showed that 1182 selected genotypes (42,9 %) were from C...
Likelihood ratio tests (LRT) were applied in an unbalanced provenance/progeny test of mate (Ilex paraguariensis A. St. Hil.). The trial was established in a randomized complete block design with seven provenances, 140 half sib families, ten blocks and six plants per linear plot. The spacing was 3 m x 2 m. The following conclusions were obtained from the deviance analysis (Anadev): all random effects and associa...
