Abstract:

cultivation areas To study the adaptability and seed yield stability, in this experiment, ten quinoa genotypes including; Red Carina, Titicaca, Giza1, Q12, Q18, Q21, Q22, Q26, Q29, Q29 and Q31 were evaluated using randomized complete block design with three replications in 2017 and 2018 in four locations; Karaj, Shahr-e-Kord, Kashmar and Urmia for their adaptability and grain yield stability. The results showed that quinoa genotypes had significant differences for most of the studied traits. However, genotype × location × year interaction effects on plant height, inflorescence length and days to flowering was not significant. Q26 genotype had the highest grain yield (2007 kg.ha-1) in Shahr-e-Kord. The lowest yield (338.33 kg.ha-1) was related to Q21 genotype in Karaj. The results of AMMI stability analysis showed that Q29 genotype had the highedt grain yiled stability with the shortest distance from the center of the graph. Cv. Giza1, cv. Red Carina, Q31 and Q26 genotypes also ranked next in terms of grain yield stability. Also, Q12, Red Carina and Q22 genotypes had specific adaptation in Karaj and Kashmar, and Giza1 and Q18 genotypes showed high specific adaptation in Urmia. In general, the results of this experiment showed that all quinoa genotypes were compatible with spring cultivation in experimental sites.  [Z1]This shows 3 years??

Distribution of minerals in quinoa (Chenopodium quinoa Willd.) seeds.

The distribution of minerals in quinoa (Chenopodium quinoa Willd.) seed was examined using energy dispersive X-ray microanalysis (EDX) in combination with scanning electron microscopy (SEM). Phosphorus, K, and Mg coincided in localization in embryonic tissue. Since phytin globoids have been known to localize in protein bodies in embryonic cells of quinoa seed, it is thought that P is attributed...

Assessment of genetic diversity in quinoa (Chenopodium quinoa Willd.) genotypes using microsatellite markers

To evaluate the genetic diversity in quinoa genotypes for future studies, 60 imported quinoa genotypes were studied using microsatellite markers (SSR) at the faculty of agricultural sciences, University of Guilan, Rasht, Iran, in 2022. The results of the phenotypic evaluation of the quinoa genotypes showed that there was a relatively high diversity among them. Among the studied traits, seed yie...

Quinoa (Chenopodium quinoa Willd.): composition, chemistry, nutritional, and functional properties.

Quinoa (Chenopodium quinoa Willd.), which is considered a pseudocereal or pseudograin, has been recognized as a complete food due to its protein quality. It has remarkable nutritional properties; not only from its protein content (15%) but also from its great amino acid balance. It is an important source of minerals and vitamins, and has also been found to contain compounds like polyphenols, ph...

The Worldwide Potential for Quinoa (Chenopodium quinoa Willd.)

Quinoa is a highly nutritious food product, being cultivated for several thousands years in South America, with an outstanding protein quality and a high content of a range of vitamins and minerals. Other positive aspects of quinoa are the saponins found in the seed hull and the lack of gluten. Quinoa is one of the main food crops in the Andean mountains, but during recent times there has been ...
