Introduction: Quinoa is a dicotyledonous plant from the Amaranthaceae family. Due to the high nutritional value of the plant, several breeding programs were started on quinoa in different parts of the world. Commercially, quinoa has three colors: black, red and white. The Sadouq variety has been introduced as a white seed variety and is tolerant to salt stress (7). The purpose of introducing the black seed variety is the market demand for the production of three-color quinoa. The aim of this research is to investigate the compatibility of quinoa variety Rahmat with black and large seeds in comparison with white seed cultivars and lines.
Materials and methods: This study was conducted during two crop years (2018-2019) in four regions (Yazd, Sabzevar, Shiraz and Iranshahr) in the form of a complete randomized block design with six genotypes and three replications. The planting date in each region was determined based on the daily weather conditions in each region. After harvesting, seed yield, 1000 seed weight, seed size and saponin content were measured. At first, Bartlett's test was performed and combined analysis and stability analysis were performed using different parametric and non-parametric methods.
Results: Combined analysis showed that the three-way interaction effect of year, place and genotype on the measured traits was significant. The highest seed yield of Rahmat cultivar observed in Iranshahr (407 g m-2) after Sadouq cultivar (488 g m-2). The lowest seed yield of Rahmat variety was observed in the studied areas in Yazd (249 g m-2). In terms of the 1000 seeds weight, the highest and lowest 1000 seeds weight were observed in Iranshahr (3.9 g) and Yazd (2.9 g), respectively. In Iranshahr, 68% and in other region 45% of the seeds of Rahmat variety were placed in the large seed size class. The saponin content of Rahmat cultivar was strongly influenced by the environment. The highest and lowest amount of saponin of Rahmat variety was observed in Sabzevar and Iranshahr. Analysis of GGEbiplot method showed that Rahmat cultivar had high specific adaptability after Sadouq in Iranshahr and Sabzevar. Based on the average total rank, Sadouq variety (1.18±2.0), C line (1.37±2.2) and Rahmat variety (2.61±3.5) had the highest grain yield stability, respectively.
Conclusion: The sum of Kang's rank and other non-parametric methods used led to the selection of stable lines in the investigated environments, but the GGEbiplot method had the ability to show the specific adaptation of the Rahmat variety with the environments. Parametric and non-parametric methods based on yield rank and stability variance showed that Rahmat cultivar was ranked third and was better than Titicaca cultivar in the investigated environments.
