Seed weight determination in quinoa (Chenopodium quinoa Willd.)
Journal of Agronomy and Crop Science, 2021AbstractExpansion 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, 2001Quinoa (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.

Characterization of quinoa (Chenopodium quinoa) lipids
Food Chemistry, 1994Abstract Lipids isolated from quinoa seed and seed fractions were characterized for lipid classes and their fatty acid composition. Quinoa seed lipids contained the largest amount of neutral lipids among all the seed fractions analyzed. A very high content of free fatty acids was detected in whole quinoa seed and hulls, accounting for 18·9 and 15·4 ...

Stability of quantitative traits in quinoa (Chenopodium quinoa)
TAG Theoretical and Applied Genetics, 1996The 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

Diseases of Quinoa (Chenopodium quinoa)
Food Reviews International, 2003Downy 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 ...

Triterpene Saponins from Debittered Quinoa (Chenopodium quinoa) Seeds
Journal of Agricultural and Food Chemistry, 2002Twelve 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 ...
