Abstract

Genetic resources of Iranian rye have high diversity in agronomic and morphological traits. Utilization of these resources is important in the development of new varieties. In this study, 9 rye ecotypes, along with commercial cultivars of rye, barley and triticale were evaluated in three growing seasons 2014-15, 2016-17 and 2017-18 in research field of Seed and Plant Improvement Institute. The research was carried out in three separate experiments in a randomized complete block design with three replications. The study of phenological, morphological and agronomic traits showed that interaction of year and ecotype was significant for all traits except for days to flowering. Based on the dry forage yield, Ecotype 119 had the highest mean and Triticale cultivar had the lowest mean. Comparison of NDF and ADF percent in the forage showed that these traits were significantly lower in ecotype 119 and barley cultivar Valfajr than other samples. Based on the average of fiber in forage, Ecotype 119 had the lowest average. It seems that Ecotype 119, in addition to high potential for forage production, also has good forage quality. Therefore, the mentioned ecotype can be used for additional evaluations and application in breeding programs.
