    J.E. Almeida Filho, F.D. Tardin, J.F.R. Guimarães, M.D.V. Resende, F.F. Silva, M.L. Simeone, C.B. Menezes and V.A.V. Queiroz

The breeding of sorghum, Sorghum bicolor (L.) Moench, aimed at improving its nutritional quality, is of great interest, since it can be used as a highly nutritive alternative food source and can possibly be cultivated in regions with low rainfall. The objective of the present study was to evaluate the potential and genetic diversity of grain-sorghum hybrids for traits of agronomic and nutrition.. Read More»

Evaluation of grain yield in sorghum hybrids under water stress

    C.B. Menezes, D.C. Saldanha, C.V. Santos, L.C. Andrade, M.P. Mingote Júlio, A.F. Portugal and F.D. Tardin

Sorghum grain yield can be significantly affected by climatic changes, especially drought and high temperature. The purpose of this study was to evaluate hybrids of grain sorghum grown under normal irrigation conditions or water stress in order to select those likely to be more tolerant of drought. Forty-nine hybrids were grown in a randomized block design experimen.. Read More»

Biplot analysis of strawberry genotypes recommended for the State of Espírito Santo

    A.F. Costa, P.E. Teodoro, L.L. Bhering, N.R. Leal, F.D. Tardin and R.F. Daher

Most strawberry genotypes grown commercially in Brazil originate from breeding programs in the United States, and are therefore not adapted to the various soil and climatic conditions found in Brazil. Thus, quantifying the magnitude of genotype x environment (GE) interactions serves as a primary means for increasing average Brazilian strawberry yields, and helps provide specific recommendations..

Adaptability and stability of genotypes of sweet sorghum by GGEBiplot and Toler methods

    U.J. de Figueiredo, J.A.R. Nunes, R.A. da C. Parrella, E.D. Souza, A.R. da Silva, B.M. Emygdio, J.R.A. Machado and F.D. Tardin

Sweet sorghum has considerable potential for ethanol and energy production. The crop is adaptable and can be grown under a wide range of cultivation conditions in marginal areas; however, studies of phenotypic stability are lacking under tropical conditions. Various methods can be used to assess the stability of the crop. Some of these methods generate the same basic information, whereas others.. Read More»

Genetic diversity between and within half-sib families of Brazil nut tree (Bertholletia excelsa Bonpl.) originating from native forest of the Brazilian Amazon

Brazil nut tree is a species of economic importance for the Amazon region, known for the commercialization of its almonds. The objective of this work was to study the genetic diversity among half-sib progenies from different Brazil nut trees present in native forest in the municipality of Itaúba, MT, belonging to the Brazilian Amazon. In a native forest area .. Read More»

Stability and adaptability of grain sorghum hybrids in the off-season

    J.E. Almeida Filho, F.D. Tardin, R.F. Daher, T.C. Barbé, C.M. Paula, M.J. Cardoso and V.P.C. Godinho

We analyzed productivity data obtained from experiments on grain sorghum conducted in 7 locations of its cultivation in Brazil. A total of 25 hybrids were analyzed, of which 22 were pre-commercial and 3 were cultivars. The Wricke and Purchase et al. methods were highly consistent in identifying individuals with low contributions to genotype x environment interaction.. Read More»

Hierarchical outcrossing among and within fruits in Bertholletia excelsa Bonpl. (Lecythidaceae) open-pollinated seeds

Knowing the mating patterns is important to determine the number of trees necessary for seed collection for conservation ex situ, tree breeding and environmental reforestation purposes. We investigated B. excelsa individuals and fruits, to check mating system index variations in a population by using open-pollinated seeds which were hierarchically sampled within and.. Read More»
