Comparison of methods to evaluate resistance of lettuce genotypes against Bremi...
Jacinto, Ana Carolina Pires; da Silveira, Aline José; da Silva, Isadora Gonçalves; Castoldi, Renata; Franco, Carolina Andrade [UNESP]Made available in DSpace on 2022-05-01T00:03:30Z (GMT). No. of bitstreams: 0 Previous issue date: 2020-08-01; Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq); For the lettuce crop, there is no specific or standard methodology to evaluate genotype resistance of lettuce against downy mildew. Therefore, the aim of this work was to compare three methodologies for the identification of resistanc...
Genetic dissimilarity for thermoinhibition in seeds of lettuce lines after defo...
Catão, Hugo Cesar Rodrigues Moreira; Maciel, Gabriel Mascarenhas; Gomes, Luiz Antonio Augusto; Siquieroli, Ana Carolina Silva; Luz, José Magno QueirozRemoval of lettuce basal leaves is a technique used by the seed industry; however, the effects on seed production and physiological potential are unknown. Genetic dissimilarity is fundamental in the identification of individuals in terms of traits of interest, although it is rarely considered in relation to seeds that are tolerant to thermoinhibition. The aim of this study was to ascertain the relationship betw...
Selection of biofortified mini lettuce progenies resistant to Pectobacterium ca...
Jacinto, Ana Carolina Pires; Castoldi, Renata; Silva, Isadora Gonçalves da; Mota, Diesiele Caroline Silveira; Moreira, Leticia GonçalvesBrazilian consumers are increasingly seeking unique vegetable products, such as mini lettuces. However, their production is hampered by a wide variety of pathogens, including Pectobacterium carotovorum subsp. carotovorum, which causes soft rot in lettuce. In this study, we aimed to select biofortified mini lettuce genotypes with good agronomic traits and resistance to P. carotovorum. A randomized block design c...
Genetic parameters and line selection of Cucurbita pepo based on selection indices
Beloti, Igor Forigo; Maciel, Gabriel Mascarenhas; Juliatti, Fernando Cezar; Finzi, Rafael Resende; Cardoso, Daniel Bonifácio OliveiraIn the improvement of pumpkins, the selection based on one or a few characters of interest tends to be less efficient, leading to a superior product only compared to the few characters selected. To maximize the simultaneous selection of multiple characteristics of interest, selection indexes are used to obtain a numerical value resulting from the combination of the characters on which the simultaneous selection...
AGRONOMIC PERFORMANCE AND PHYSIOLOGICAL QUALITY OF PEPPER SEEDS UNDER DIFFERENT...
Beloti, Igor Forigo; Nunes Rodrigues de Azevedo, Breno; Maciel, Gabriel Mascarenhas; Peres, Hugo Gabriel; Pivetta Momesso, Mauricio; Alves, Igor MatheusThe pepper crop is cultivated in all Brazilian regions,and the planting system with the arrangement of plants in the single-row prevails. Therefore, this work aimed to evaluate the agronomic performance and physiological quality of the seeds of different pepper genotypes according to the planting systems. The experiment was carried out at the Federal University of Uberlândia, in Monte Carmelo, in a randomized b...
GENETIC DISSIMILARITY BETWEEN LETTUCE GENOTYPES WITH DIFFERENT LEVELS OF CAROTE...
Silveira, Aline José da; Finzi, Rafael Resende; Cabral Neto, Luciano Dias; Maciel, Gabriel Mascarenhas; Beloti, Igor Forigo; Jacinto, Ana Carolina PiresDIVERSIDADE GENÉTICA ENTRE GENÓTIPOS DE ALFACE COM DIFERENTES NÍVEIS DE BIOFORTIFICAÇÃO POR CAROTENÓIDES Alimentos ricos em carotenóides podem auxiliar na prevenção de diversas doenças. A alface é uma das hortaliças mais consumidas no mundo apresentando potencial para investimento em biofortificação. No entanto, existem poucos genótipos de alface biofortificado disponíveis no mercado, inclusive, para uso direto...
Estresse hídrico induzido por manitol para seleção de genótipos de tomateiro
Maciel, Gabriel Mascarenhas; Berenguer, Andrea Farneze; da Silva, Ernani Clarete; Fraga Junior, Eusímio Felisbino; Rocha, Debora KelliA seleção de genótipos tolerantes ao déficit hídrico pode beneficiar a culturado tomateiro favorecendo maiores produtividades. O objetivo do trabalho foi avaliar apotencialidade de solução osmótica de manitol como simulador de deficiência hídrica paraseleção de genótipos de tomateiro. Adotou-se o delineamento inteiramente casualizado (DIC)com quatro repetições. Avaliou-se a melhor concentração de manitol capaz ...
Physiological quality of parsley seeds in relation to doses of nitrogen and pot...
Maciel, Gabriel Mascarenhas; Carvalho, Fábio Janoni; Almeida, Cinara Xavier de; Luz, José Magno Queiroz; Nogueira, Gregory Gustavo SilvaParsley seeds [Petroselinum crispum (Mill.) Nyman ex AW Hill] must have germinations higher than 70%. But seed companies have found difficulties to get the minimum standards of germination established for this species, because of the slow and irregular germination after harvesting. The aim of this study was to evaluate the effect of nitrogen and potassium fertilization on the physiological quality of parsley se...
Growth habit in mini tomato hybrids from a dwarf line
Finzi, Rafael Resende; Maciel, Gabriel Mascarenhas; Luz, José Magno Queiroz; Clemente, Andressa Alves; Siquieroli, Ana Carolina SilvaThe growth habit directly influences the tomato architecture, impacting on agronomic performance of mini-tomato hybrids. However, little is known about the growth habit of mini-tomatoes hybrids obtained by the crossing of dwarf lines versus normal lines with different growth habits. The objective of this study was to determine the type of growth that occurs when crossing a mini-tomato dwarf line versus normal p...
Physical and chemical characteristics of lettuce cultivars grown under three pr...
Moreira Martins, Luma; da Silva, Ernani Clarete; Carlos, Lanamar de Almeida; de Castro Louback Ferraz, Leila; Maciel, Gabriel MascarenhasCharacteristics of food quality can affect the health of consumers and are influenced by several factors including the system of production. Lettuce has the highest sales volume of any leafy vegetable sold in Brazil and is considered a good source of vitamins, minerals and other compounds. This study aimed to determine the influence of the type of production system (conventional, organic and hydroponic) on the ...
