Major QTL for carrot color are positionally associated with carotenoid biosynthetic genes and interact epistatically in a domesticated x wild carrot cross. 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. 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.

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
Evaluation of tropicalized carrot lines using partial diallel. Author(s): CARVALHO, A. D. F. de; SILVA, G. O. da The objective of this study was to evaluate the effects of general (GCA) and specific (SCA) combining ability between different summer carrot lines for production components, tolerance to leaf blight,... ...

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. 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
Use of water restriction in the inoculation of carrot seeds. Author(s): PEREIRA, R. B.; PINHEIRO, J. B.; NASCIMENTO, W. M. ABSTRACT: This study aimed at evaluating the method of inoculation of carrot seeds in a potato-dextrose-agar medium (PDA) added of mannitol. Alternaria radicina was the fungus chosen to test such meth... ... Repository: BDPA Publication year: 2019
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
Path analysis suggests phytoene accumulation is the key step limiting the carotenoid pathway in white carrot roots. 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... ...

Planting times and spacing of carrot crops in the São Francisco Valley, Pernambuco state, Brazil. Climate variations over the year and plant density tend to strongly affect the agronomic performance of carrot crops. Thus, the objective of this work was to evaluate the performance of the cultivar B... ... Repository: BDPA Publication year: 2016
