The objectives of this study were to evaluate the relationships between morphological characteristics and fresh matter yield cactus pear identify their direct indirect effects. Nineteen accessions evaluated for following traits: number (NCl), thickness (ThCl), length (LCl) width (WCl) cladodes, plant height (PH) (PW), green (GMY), dry (DMY) percentage (DM). correlations estimated, path analysis was performed by method proposed Wright. GMY strongly correlated with DMY, allowing selection...
Historicamente a bataticultura brasileira tem utilizado cultivares desenvolvidas em países de clima temperado, principalmente da Europa, estas pouco adaptadas às nossas condições ambientais, ao fotoperíodo mais curto, temperaturas médias elevadas, solos pobres e maior pressão patógenos pragas. Objetivou-se avaliar clones avançados batata obtidos pelo programa melhoramento genético Universidade Federal Lavras (UFLA), resistentes principais doenças, com ampla adaptação várias épocas plantio no...
A demanda por frutos de umbuzeiro e grande no Nordeste brasileiro, entanto, plantios comerciais sao ausentes a producao obtida forma extrativista. Assim, estrategias voltadas para identificacao selecao genotipos superiores o estabelecimento um programa melhoramento cultura necessarias. coleta, caracterizacao avaliacao do germoplasma etapas essenciais se obter exito nesse processo. Esse trabalho teve objetivo avaliar caracteristicas fisicas 58 acessos umbuzeiro, coletados na Paraiba Rio...
Clonal selection is the preferred breeding method used in potatoes (Solanum tuberosum L.). However this procedure only efficient for more advanced generations and shows no good results when applied seedling up to second clonal generation. This study assessed feasibility of early full-sib potato families compares among within with combined under different intensities. Six experiments were conducted from first (C1) until third generation (C3). In C1 a randomized complete block design four...
ABSTRACT Pepper is one of the main vegetable crops commercialized in Brazil and it grown throughout country. The objective this study was to estimate genetic parameters predict genotypic values involved agronomic traits hybrid pepper two different cropping systems order verify adaptability stability. experiment carried out at Experimental Station Luiz Jorge da Gama Wanderley from IPA, located Vitoria de Santo Antão, Pernambuco State, Brazil, October 2010 March 2011. Seven hybrids were...
O objetivo do presente trabalho foi selecionar clones de batata com elevado desempenho agronômico e resistência à pinta preta aos vírus X Y. Para tanto, foram realizados 57 cruzamentos entre portadores dos alelos Ry adg Rx1, a cultivar 'Chiquita', resistente (Alternaria solani). Na safra das águas 2004, famílias clonais avaliadas em campo 331 selecionados considerando aparência tubérculos. Desse total clones, avaliados mais dois experimentos no verão 2005, 180 por meio marcador SCAR RYSC3...
This study aimed to estimate the general-(GCA) and specific-combining ability (SCA) obtain information on genetic control of agronomic traits among six upland cotton genotypes their hybrid combinations.In 2015, (FM 993, CNPA 04-2080, PSC 355, TAM B 139-17, IAC 26, TAMCOT-CAMD-E), fifteen combinations were evaluated at Experimental Station Embrapa Algodão.The experiment consisted a randomized block design with three replications.The characteristics were: appearance first flower (AFF); D.R....
Objetivou-se avaliar o acúmulo de biomassa e crescimento radicular da palma forrageira (Opuntia ficus indicaMill) em diferentes épocas colheita. O delineamento estatístico foi inteiramente casualizado com dez tratamentos três repetições por tratamento. Foi utilizada uma área 12.100 m² clone IPA 20. As avaliações procederam-se após 90 dias do estabelecimento planta no campo, sendo que as demais foram feitas a cada 45 dias, realizando-as 90º, 135º, 205º, 252º, 300º, 345º, 390º, 435º, 480º 525º...
ABSTRACT Genome-wide selection (GWS) uses simultaneously the effect of thousands markers covering entire genome to predict genomic breeding values for individuals under selection. The possible benefits GWS are reduction cycle, increase in gains per unit time, and decrease costs. However, success is dependent on choice method effects markers. Thus, objective this work was (GEBV) through artificial neural networks (ANN), based estimation markers, compared Ridge Regression-Best Linear Unbiased...
Final cotton quality is of great importance, and it depends on intrinsic extrinsic fiber characteristics.The objective this study was to estimate general (GCA) specific (SCA) combining abilities for technological traits among six upland genotypes their fifteen hybrid combinations, as well determine the effective genetic effects in controlling evaluated.In 2015, genotypes: FM 993, CNPA 04-2080, PSC 355, TAM B 139-17, IAC 26, TAMCOT-CAMD-E combinations were evaluated at Experimental Station...
A mancha anular do cafeeiro, causada pelo Coffee ringspot virus (CoRSV) que é transmitido ácaro Brevipalpus phoenicis (Geijskes) (Acari: Tenuipalpidae), tem sido observada em altas incidências várias regiões cafeeiras Estado de Minas Gerais. O CoRSV causa manchas cloróticas arrendondadas ou irregulares nas folhas, caules e frutos. Foi feita uma avaliação efeito da infecção frutos cafeeiro na qualidade bebida por meio teste bioquímico degustação, também eventual perda peso nos grãos. Testes...
ABSTRACT This study aimed to characterize and select silk blossom genotypes (Calotropis procera) with forage potential. Between April July 2014, we cultivated 89 in plastic tubes arranged a randomized block design three replications; each experimental plot was composed of 8 plants. The following characteristics were evaluated: plant height (PH), stem diameter (SD), number leaves (NL), total leaf area (TLA), fresh mass (LFM), (SFM), root (RFM), dry (LDM), (SDM), (RDM). Significant differences...
Maize is a crop of significant economic importance. In the northeast region Brazil, it serves as foundation family support for majority farmers. However, achieving high levels productivity requires an adequate water supply throughout its growth cycle. The semi-arid experiences low rainfall and potential evapotranspiration, directly affecting maize development leading to severe declines in productivity. this study, genetic selection proteomic analysis are proposed strategy identify tolerance...
