“…The colored quinoa variety P had the highest pyridoxine content of all varieties of all crops (Table 1). Quinoa varieties used in this study showed low variability in B2 and B6 vitamin content (0.24 to 0.46 mg/kg and 0.4 to 1.35 mg/kg, respectively) compared to previous reports using different varieties (0.6 to 3.9 mg/kg and 4.1 to 5.5 mg/kg of B2 and B6, respectively) (Miranda et al, 2012;Ruales & Nair, 1993;Wu, 2015;USDA, 2016). The importance of these compounds in quinoa has been previously confirmed by determining high free radical scavenging activity for thiamine, followed by folic acid and vitamin B6 forms (Gliszczynska-Swiglo, 2006).…”

“…is an ancient seed crop from the Andean region, and in the last 30 years, it has gained considerable attention worldwide due to its nutritional and health benefits, as well as its flavourful and high‐quality seeds (Aluwi, Murphy, & Ganjyal, ; Kowalski, Medina‐Meza, Thapa, Murphy, & Ganjyal, ; Wu, Morris, & Murphy, , ; Wu, Ross, Morris, & Murphy, ). Most notably, it is prized for its well‐balanced complement of amino acids and high mineral concentration of iron, calcium and phosphorus (González, Konishi, Bruno, Valoy, & Prado, ; Navruz‐Varli & Sanlier, ; Vega‐Gálvez et al., ; Wu, ; Wu, Peterson, Morris, & Murphy, ). In the last few years, quinoa production has been spreading around the world (Bazile, Jacobsen, & Verniau, ; Jacobsen, ).…”

Quinoa (Chenopodium quinoa Willd.) has gained considerable attention worldwide during the past decade due to its nutritional and health benefits. However, its susceptibility to high temperatures has been reported as a serious obstacle to its global production. The objective of this study was to evaluate quinoa growth and pollen morphology in response to high temperatures. Pollen morphology and viability, plant growth and seed set, and several physiological parameters were measured at anthesis in two genotypes of quinoa subjected to day/night temperatures of 22/16°C as a control treatment and 40/24°C as the heat stress treatment. Our results showed that heat stress reduced the pollen viability between 30% and 70%. Although no visible morphological differences were observed on the surface of the pollen between the heat‐stressed and non‐heat‐stressed treatments, the pollen wall (intine and extine) thickness increased due to heat stress. High temperature did not affect seed yield, seed size and leaf greenness. On the other hand, high temperature improved the rate of photosynthesis. We found that quinoa has a high plasticity in response to high temperature, though pollen viability and pollen wall structure were affected by high temperatures in anthesis stage. This study is also the first report of quinoa pollen being trinucleate.

“…There are thought to be two centers of domestication, one in the Andean highlands and one in the southwestern South American costal lowlands (Jarvis et al 2017). Quinoa is more nutritious than rice because of its high-protein content of about 16.5% and its beneficial ratios of amino acids (Wu 2015). There has been tremendous market growth and commercial excitement about quinoa since 2007 (Núñez De Arco 2015).…”

The wild-growing relatives of the grain crops are useful for long-term worldwide crop improvement research. There are neglected examples that should be accessioned as living seeds in gene banks. Some of the grain crops, amaranth, barnyard millet, proso millet, quinoa, and foxtail millet, have understudied unique and potentially useful crop wild relatives in North America. Other grain crops, barley, buckwheat, and oats, have fewer relatives in North America that are mostly weeds from other continents with more diverse crop wild relatives. The expanding abilities of genomic science are a reason to accession the wild species since there are improved ways to study evolution within genera and make use of wide gene pools. Rare wild species, especially quinoa relatives in North American, should be acquired by gene banks in cooperation with biologists that already study and conserve at-risk plant populations. Many of the grain crop wild relatives are weeds that have evolved herbicide resistance that could be used in breeding new herbicide-resistant cultivars, so well-documented examples should be accessioned and also vouchered in gene banks.
