Abstract:
Quinoa, the new functional grain crops which suitable for highland cultivation. However, the environmental response was still the barrier for high yield production. The experiment was aimed to study for genetic diversity,physiological responsibility and yield in different grownconditions. This research was used the 24 accessions of quinoa and arranged based on randomized complete block design with 4 replications and combined with 3 locations. AFLP marker was performed over the 24 accessions, including cluster analysis with UPGMA . According to genetic background, if can clustered into three major groups. Yield stability was analyzed using GGE biplot. The experiment found that genetic background was diverse among quinoa accessions. Geometrically profile of those 24 accessions adapted and responded in all parameters except LAR was significantly affected by different both of genetically background and environment. The positive correlation showed significantly positive between yield and crop growth rate, dry weight, and net assimilation rate, while significantly negative to leaf area ratio during the harvesting period. Yield stability from GGE biplot method showed the KU23 was the best yield potential at DP, while KU18 was the most suitable to yield potential at PD and HT. The experiment concluded that KU18 was the most recommended for growth potential and provided high yield production in all locations. Furthermore, the breeding programs based on the optimum ecotype could be enhancing the expansion of quinoa production area including bioeconomic based on local highland agricultural system development.
