Abstract
O objetivo deste trabalho foi avaliar a produtividade e obter as estimativas de parâmetros geneticos e nao geneticos de 40 materiais geneticos do programa de melhoramento genetico de cafe Conilon do Incaper, no Estado do Espirito Santo. Foram analisados dados de dois experimentos, nos municipios de Marilândia e Sooretama, ES, nas safras de 1996, 1997, 1998, 1999, 2000, 2001 e 2002, em que se avaliaram 16 caracteristicas. Realizou-se, inicialmente, a analise de variância individual, por local em cada ano, com base na media de parcelas, em blocos ao acaso. Posteriormente foi feita a analise de variância conjunta. Os genotipos apresentaram grande variabilidade genetica para a maioria das caracteristicas avaliadas. Os elevados coeficientes de determinacao genotipico e coeficientes de variacao geneticos, associados as altas produtividades e a variabilidade genetica indicam a possibilidade de obtencao de exitos em programas de melhoramento genetico para diferentes caracteristicas avaliadas nos dois municipios.

Combined Selection in Backcross Population of Papaya (Carica papaya L.) by the Mixed Model Methodology

TL;DR: This study aimed to apply the combined selection by using distinct selection indexes based on both the genetic values obtained by the REML/BLUP methodology and the real measured values to select agronomically superior genotypes of papaya within backcross progenies.

Divergence and genetic parameters between coffea sp. genotypes based in foliar morpho-anatomical traits

TL;DR: The objective of this work was to estimate the genetic parameters, and to study genetic divergence in a coffee plants population constituted by 30 genotypes of Coffea canephora and 4 of C. arabica by means of univariate and multivariate statistical procedures based on easy to obtain leaf morpho-anatomic characteristics.

Efficiency and response of conilon coffee clones to phosphorus fertilization

TL;DR: The results indicate a differentiated response of dry matter production and of phosphorus content on each level of phosphate fertilization for the conilon cof fee clones and that CV-04, CV-05 and CV-08 clones are nutritionally eficient and responsive to the phosphorous fertilization.

Reciprocal recurrent selection applied to Coffea canephora Pierre

TL;DR: Genetic parameters were estimated in trials planted in connection with a reciprocal recurrent selection programme applied to Coffea canephora in Côte d'Ivoire and Phenotypic and genetic correlations between tree vigour traits and productivity were high.

Prediction of genetic value for coffee production in Coffea arabica from a half-diallel with lines and hybrids

TL;DR: Indirect prediction of yield using morphological traits gave the same value for expected genetic gain as the prediction based on cumulated yield over four years, and the application of these results to coffee breeding strategies involving hybrid selection is discussed.

Genetic parameters of several biochemical compounds from green coffee, Coffea canephora

TL;DR: A factorial crossing scheme of #Coffea canephora# (two parents from the Congolese group crossed to 14 parents of the Guinean group) was used to evaluate genetic parameters of several biochemical compounds, bean weight and crop outturn, and additive genetic effects were preponderant.
