Major QTL for carrot color are positionally associated with carotenoid biosynthetic genes and interact epistatically in a domesticated x wild carrot cross. Author(s): JUST, B. J.; SANTOS, C. A. F.; YANDELL, B. S.; SIMON, P. W. We performed QTL analyses for pigment content on a carotenoid biosynthesis function map based on progeny of a wild white carrot (QAL) which accumulates no pigments x domesticated orange carrot (B493),... ...

Heritabilities and minimum gene number estimates of carrot carotenoids. Author(s): SANTOS, C. A. F.; SIMON, P. W. Broad sense heritabilities and gene numbers were estimated for the production of total carotenoids and the major component carotenoids of carrot storage roots: phytoene, carotene, aned lycopene. Repository: BDPA Publication year: 2006
Powdery mildew caused by Erysiphe heraclei: a novel field disease of carrot (Daucus carota) in Brazil. Author(s): BOITEUX, L. S.; REIS, A.; FONSECA, M. E. de N.; LOURENÇO JUNIOR, V.; COSTA, A. F.; MELO, A. G.; BORGES, R. C. F. Carrot powdery mildew was first detected in seed production fields of the cultivar Brasília in Brasília-DF in 2008. White cottony growth was observed on leaves, petioles, and floral stalks. In 2014 to... ... Repository: BDPA Publication year: 2017
Path analysis suggests phytoene accumulation is the key step limiting the carotenoid pathway in white carrot roots. Author(s): SANTOS, C. A. F.; SENALIK, D.; SIMON, P. W. Two F 2 carrot (Daucus carota L.) populations (orange rooted Brasilia x very dark orange rooted High Carotene Mass - HCM cross and the dark orange rooted cultivated variety B493 x white rooted wild ca... ...

Post-emergence selectivity of metribuzin to carrot. Author(s): CORREIA, N. M.; CARVALHO, A. D. F. de The objective of this study was to evaluate the selectivity of the herbicide metribuzin to carrot plants as a function of genotype, dose, and plant growth stage at the time of application. Two experim... ... Repository: BDPA Publication year: 2018
Carotenoid biosynthesis structural genes in carrot (Daucus carota): isolation, sequence-characterization, single nucleotide polymorphism (SNP) markers and genome mapping. Author(s): JUST, B. J.; SANTOS, C. A. F.; FONSECA, M. E. N.; BOITEUX, L. S.; OLOIZA, B. B.; SIMON, P. W. Carotenoid pigments are important components of the human diet and carrots are the main dietary sources of the vitamin A precursors IX- and /3- carotene. Carotenoids play essential biological roles in... ... Repository: BDPA Publication year: 2007
Direct selection for phenotypic traits in carrot genotypes. Author(s): CARVALHO, A. D. F. de; SILVA, G. O. da; PEREIRA, G. E. The aim of this work was to evaluate gains from direct selection and to measure its effects on other agronomic traits of interesti in carrots. Repository: BDPA Publication year: 2019
Evaluation of summer carrot cultivars in bed and ridge systems. Author(s): CARVALHO, A. D. F. de; SILVA, G. O. da; GUEDES, S. F.; PEREIRA, E. de C.; MARTINS, G. P.; MAGALHÃES, C. da C. In Brazil, carrots are usually grown in beds 30 cm heigh and 1 to 1.8 width. Although widely used, these beds present problems regarding cultural practices and disease management, especially in spring... ... Repository: BDPA Publication year: 2023
Carrot seed germination and ethlene production at high temperature in response to seed osmopriming. Author(s): NASCIMENTO, W. M.; HUBER, D. J.; CANTLIFFE, D. J. O objetivo deste estudo foi determinar se a tolerancia de sementes osmocondicionadas de cenoura à germinação sob altas temperaturas está associada ao aumento da produção de etileno. Repository: BDPA Publication year: 2013
BRS Paranoá: carrot for organic production systems. Author(s): CARVALHO, A. D. F. de; RESENDE, F. V.; SILVA, G. O. da; PINHEIRO, J. B.; PEREIRA, R. B.; NASCIMENTO, W. M.; PILON, L. ?BRS Paranoá? was obtained by the carrot breeding program of Embrapa Hortaliças, aiming to obtain a cultivar adapted to most carrot-producing regions in an organic system. It was developed through sel... ... Repository: BDPA Publication year: 2022
