“…Some reports mentioned that Chilean germplasm is more tolerant to high temperatures than Andean germplasm (Choukr‐Allah et al., ; Isobe, Uziie, Hitomi, & Furuya, ; Peterson & Murphy, ). However, cultivars such as “Salcedo” from Bolivia and “Achachino” from Peru performed better in high temperatures, demonstrating that high tolerance is not strongly correlated with the geographic origin of the quinoa genotype.…”

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.

multi environmental trial involving five quinoa genotypes i.e., KVL-SRA2, KVL-SRA3, Regalona, Q-37 and Q-52 was conducted along the North Western Coast of Egypt. The eight tested environments included two sites in the first season of 2014/2015 i.e. irrigated Matrouh and rainfed Matrouh, while in the second season of 2015/2016 there were six sites including three rainfed sites of Ras El Hekma, El Neguilla and Matrouh as well as an irrigated site in Matrouh with three planting dates i.e., 1 Nov.,15 Nov., and 1 Dec. Grain yield was significantly influenced by both genotypes and environments; Regalona genotype produced the highest grain yield in most of the studied environments (6 out of 8 environments) with the highest grain yield of 3.08 t/ha in irrigated Matrouh site in the first season. Moreover, it showed more drought tolerance as compared to the other genotypes. The environment effect was the major source of variation as compared to the genotype and genotype × environment interaction effects, and attributed to 88.5% of the total variation in the grain yield. Two-mode pattern analysis of the environment-standardised matrix of grain yield revealed three genotypic groups of different response pattern across environments. In general, the grain yields of the genotypes were lower under rainfed conditions as compared to irrigated conditions, except for Matrouh in the second season for the late irrigated planting dates i.e., 15 Nov. and 1Dec. The high tolerance of quinoa to drought makes it an excellent choice for the diversification of future agriculture in the North Western Coast of Egypt and other regions with similar harsh conditions.

“…This Andean grain is an important crop of the Andean region in South America from Colombia (2°N) to central Chile (40°S) (Risi and Galwey, 1984;Jacobsen et al, 2003). Quinoa has recently gained worldwide attention because of its ability to be reproductive under various stress conditions (Choukr-Allah et al, 2016). Quinoa as a halophytic species has the ability to cope with salinity levels as high as those present in sea water Hariadi et al, 2011;Shabala et al, 2013;Panuccio et al, 2014).…”

A prerequisite for sustainable saline agriculture of cash crop halophytes in salt affected areas implies exact knowledge of their limits of salinity resistance. Hence, the first part of this study was carried out in pot experiment under greenhouse conditions to evaluate growth and seed yield of C. quinoa Willd. cv. Hualhuas to varying water salinity levels (0, 100, 200, 300, 400 and 500 mM NaCl). The limit of salinity resistance was estimated at 200 mM NaCl (~20 dSm -1 ) based on seed yield production. Depending on the results obtained from pot experiment, field trials were conducted in saline soil location (ECe 17.9 dSm -1 ) and in non-saline soil location (ECe 1.9 dSm -1 ). Seed yield significantly decreased under saline soil by about 61.7% . Beside quantity, soil salinity led to reduce the percentage of moisture, total carbohydrate and total fat contents in seeds. Salinity did not significantly alter the protein content in quinoa seeds. Significant increases in the content of ash and fiber were detected in response to high soil salinity. The high er ash content in seeds under saline conditions was due to the increase of Na + as well as K + , P 3-and Fe ++ concentrations. By contrast, soil salinity led to significant decrease of Ca ++ and Zn ++ contents in seed. Energy dispersive X-ray microanalysis showed that most of Na + in the seeds produced at saline soil was mainly accumulated in the pericarp followed by embryo tissues, while, the interior reserving tissue (perisperm) exhibiting comparatively low concentration. Increasing most of essential minerals, especially Fe, in quino a seeds produced under high saline conditions given quinoa a distinctive value for human consumption. Quinoa can be grown and yielded successfully in salt-affected soils (ECe 17.9 dSm -1 ), where, most if not all of traditional crops cannot grow, although the yield was reduced however, the seed quality was not highly affected.
