Seed weight determination in quinoa (Chenopodium quinoa Willd.)

Journal of Agronomy and Crop Science, 2021
AbstractExpansion into areas outside their centres of origin requires knowledge of quinoa's physiology and its response to the environment concerning the determination of seed yield and its numerical components to facilitate crop management and breeding.

Ecdysteroids of Quinoa Seeds (Chenopodium quinoa Willd.)

Journal of Agricultural and Food Chemistry, 2001
Quinoa (Chenopodium quinoa) is a hardy and nutritious Latin American pseudo-cereal. Studies on the seeds led to the isolation of five ecdysteroids using column chromatography. Their structures were determined as ecdysterone, makisterone A, 24-epi-makisterone A, 24(28)-dehydromakisterone A, and 20,26-dihydroxyecdysone by spectroscopic methods.

Stability of quantitative traits in quinoa (Chenopodium quinoa)

TAG Theoretical and Applied Genetics, 1996
The stability of various descriptive characters was studied over a 5-year period in 14 lines of quinoa (Chenopodium quinoa Willd.) to determine the most appropriate time in a breeding programme when selection for these characters could be performed, and which lines could serve as potential parents. Various measures of stability were employed to analyse

Two flavonol glycosides from Chenopodium quinoa

Phytochemistry, 1990
Two new flavonol glycosides from the seeds of Chenopodium quinoa have been isolated. Their structures were established as kaempferol 3-apiofuranosyl(1"'----2")rhamnopyranosyl(1""----6")galactoside and kaempferol 3-apiofuranosyl(1"'----2")rhamnopyranosyl(1""----6")galactoside.

Diseases of Quinoa (Chenopodium quinoa)

Food Reviews International, 2003
Downy mildew caused by Peronospora farinosais the most damaging disease of quinoa (Chenopodium quinoa), an ancient Andean grain crop. The disease has been reported from all areas of quinoa cultivation. In the Andean highlands, it is considered endemic. Despite the disease's wide dissemination and significant effect on quinoa crop production, little is ...

Nutritional and health benefits of quinoa ( Chenopodium quinoa Willd.)

Journal of Cereal Science, 2016
Quinoa (Chenopodium quinoa Willd.) is a plant species of the Chenopodiaceae family, which originated in the Andean region and can adapt to different types of soil and climatic conditions. It is a pseudo grain with high nutritional value as it is rich in proteins, lipids, fiber, vitamins, and minerals, and has an extraordinary balance of essential amino

Triterpene Saponins from Debittered Quinoa (Chenopodium quinoa) Seeds

Journal of Agricultural and Food Chemistry, 2002
Twelve triterpene saponins have been isolated from the debittered seeds of quinoa (Chenopodium quinoa), and their structures were characterized on the basis of hydrolysis and spectral data, especially NMR evidence. Among them, three compounds, including 3-O-beta-D-glucuropyranosyl oleanolic acid (1), 3-O-beta-D-glucopyranosyl-(1-->3)-alpha-L ...

New Oleanane Saponins in Chenopodium quinoa

Journal of Agricultural and Food Chemistry, 2001
Six triterpenoid saponins were isolated from the seeds of Chenopodium quinoa (Chenopodiaceae). Their structures were as follows: phytolaccagenic acid 3-O-[alpha-L-arabinopyranosyl-(1' '-->3')-beta-D-glucuronopyranosyl]-28-O-beta-D-glucopyranoside (1); spergulagenic acid 3-O-[beta-D-glucopyranosyl-(1-->2)-beta-D-glucopyranosyl-(1-->3)-alpha-L ...

Breeding quinoa (Chenopodium quinoa Willd.): potential and perspectives

Molecular Breeding, 2014
Quinoa (Chenopodium quinoa Willd.) originated in the Andean region of South America; this species is associated with exceptional grain nutritional quality and is highly valued for its ability to tolerate abiotic stresses. However, its introduction outside the Andes has yet to take off on a large scale.

Frost resistance mechanisms in quinoa (Chenopodium quinoa Willd.)

European Journal of Agronomy, 2007
Abstract Quinoa (Chenopodium quinoa Willd.) is traditionally grown in the mountain regions of the Andes where frost is common. However, the physiological mechanisms responsible for the frost resistance observed in quinoa are largely unknown. For this reason, a study on cultivars of quinoa originating from the Andean highlands and from the inter ...
