Abstract

Statement of the Problem: As being the first cultivated wheat in the Fertile Crescent, diploid einkorn wheat (2n=2x=14, AA), Triticum monococcum L. subs. monococcum, was domesticated 9500 years ago in Karacadag Mountains of South-East Turkey. Nowadays it has been grown in only marginal lands of Turkey, Caucasus, Europe and Morocco. After having disappeared because of its replacement by high yielding modern wheat cultivars, recently einkorn wheat has been re-introduced in some countries, especially for organic farming, due to its high resistance to pests and diseases, adaptation to harsh climates, ability to provide acceptable yields on poor soils even with low/ without inputs and high nutritional value. In order to maintain and utilize the genetic diversity of einkorn wheat, it is necessary to develop in situ conservation program to provide continuity of cultivation of its landraces; characterizing, analyzing and documenting of its accessions and identifying its genes for useful agronomical and nutritional traits to employ in breeding programs.

Materials and Methods: Local 45 einkorn wheat lines, selected from 500 single rows planted by each single spikes collected from 50 farmers鈥� fields in Kastamonu/Turkey, were sown in autumn (9 November 2017) and in spring (20 February 2018) and were harvested on 30-31 July 2018 and on 8 August 2018, respectively. Morphologic and agronomic traits were observed and measured during growing period of plants and quality properties of harvested seeds were determined by using 鈥淪ingle Kernel Characterization System (SKCS)鈥�.

Findings: All of the einkorn wheat lines in the trial showed 鈥渇acultative鈥� growth habit, flowering well when sown both in autumn and in spring. Although lines sown in autumn had more yield, the same lines sown in spring provided higher quality and more resistance to lodging due to being shorter.

Conclusions: Einkorn wheat lines sown in autumn and in spring seasons showed a significant variation for traits, which can be used for einkorn breeding program.
