Abstract

Quinoa (Chenepodium quinoa Willd.) is a grain-like crop which has a high grown potential in Iran. Due to it's seed have high nutritional value, therefore, compared to milk nutrition by the FAO. This study aims to determine the seed dormancy and pre-harvest sprouting three cultivars of quinoa. This plant was planted in a randomized complete block design at the research farm of university of Tehran and, phonological traits were recorded. Then the related studies such as seed dormancy and pre-harvest evaluation resistance were conducted in two 15 and 25°C constant temperatures in seed laboratory. The results shown that there is significant genetic variation for pre-harvest sprouting and other traits. The results demonstrate that Titicaca and Santamaria have lowest and highest germination in cluster, respectively. Also, Titicaca cultivar related to the other cultivars have had high percentage of seed dormancy. The results shown that it is possible to handle the quinoa crop in such areas which have frequent risk of PHS.
