Heat is one of the major abiotic stresses that affect wheat yield and quality in many parts of the world. To overcome this problem, the development of heat tolerant cultivars has been shown to be one of the main targets of breeding programs, especially for the conditions of Central Brazil. The present study was developed with objective of identifying promising populations for tolerance to heat stress, in order to obtain lines adapted to the conditions of Central Brazil. The experiment was carrie...

Abstract Despite being a species with great potential for biodiesel production, little research has been done on the breeding of Jatropha curcas , mainly with respect to its yield across harvests. Thus, the present study was carried out to analyze longitudinal data via multiple-trait Best Linear Unbiased Prediction (BLUP) for the genetic improvement of Jatropha curcas . The experiment was set up as a randomized block design with two blocks and five plants per plot. The seed yield of 730 individu...

The wheat blast disease has been considered one of the main biotic stress threats to food security in the world. The study aimed to evaluate the resistance of wheat cultivars to Pyricularia oryzae pathotype triticum isolates at the vegetative and reproductive stage and to perform screening of wheat lines. Experiments were carried out on plants at the vegetative and reproductive stage, with artificial inoculation of P. oryzae pathotype triticum isolates origin from different producing regions. Re...
Usually, genetic selection is carried out based on several traits, which can be genetically correlated. In this case, selection bias may occur if these traits are analyzed individually. Thus, the present work aimed to evaluate the applicability and efficiency of multiple-trait best linear unbiased prediction (BLUP) in the genetic selection of Eucalyptus. The data used in this work refer to the evaluation of a partial diallel of Eucalyptus spp. in relation to height, diameter at breast height (DB...
Abstract Persistence may be defined as high sustained yield over multi-harvest. Genetic insights about persistence are essential to ensure the success of breeding programs and any biomass-based project. This paper focuses on assessing the biomass yield persistence for bioenergy purpose of 100 elephantgrass clones measured in six growth seasons in Brazil. To assess the clones' persistence, an index based on random regression models and genotype-ideotype distance was proposed. Results suggested th...

Estudos da transmissao de Pyricularia graminis-tritici pela semente de trigo podem auxiliar no estabelecimento de padroes de tolerância do patogeno na cultura. Quatro genotipos diferentes quanto a reacao a brusone foram inoculados com cinco volumes da suspensao fungica (1,5x10 5 esporos.mL -1 ), de modo a obter 0, 5, 10, 20 e 30% de plantas inoculadas na unidade experimental. O potencial de transmissao de P. graminis-tritici planta-semente foi avaliado pela incidencia do fungo nas sementes produ...
