Abstract

The present s tudy was conducted in Agricultural Research Ins titute of the Hungarian Academy of Sciences, Martonvásár,

Hungary, from 7th September 2015 to 31s t July 2016, and aimed to evaluate the crossabilities of 6 Triticum durum (Ç-1252,

Kızıltan, Altıntaş, Dumlupınar Yelken and Kunduru) with 6 Aegilops tauschii (MVGB605, MVGB1323, MVGB589,

CIMMYT224, CIMMYT372 and CIMMYT458). Triticum durum and Aegilops tauschii parents had been successfully

grown, and the desired number of spikes had been emasculated and pollinated (total 171 spikes). Total 34 combinations

were made and 164 embryos were obtained from 19 combinations among them. There were no embryos in 15 combinations.

Number of maximum embryo rescue was obtained from Yelken/MVGB589 combination (24 embryos). It was followed

by Kızıltan/MVGB589, Ç-1252/MVGB589 and Ç-1252/2T combinations (16, 13 and 11 embryos, respectively). 70

germinated plants were obtained from 164 embryos in B-5 medium (in petri dishes). 94 embryos were not germinated.

A total of 29 germinated embryos died in two B-5 medium (petri dish and tube). Some older and younger tillers died

after colchicine treatment. However, we had new shooting tillers. According to results, the bes t females were Yelken

and Ç-1252 among Triticum durums, while the bes t male MVGB589, CIMMYT224 and MVGB1323 among Aegilops

tauschiis, respectively.
