| Abstract | ||
| 30 triticale genotypes (29 genotypes introduced from CIMMYT as well as Rwaida the local variety ) were planted for two consecutive seasons 2009-2010 and 2010-2011 in two sites ; first in the fields of the college of Agriculture and Forestry / University of Mosul, the second in a research station Cardhrash–college of Agriculture / University of Salahaddin (Arbil). Four techniques has been compared with the safety-first selection indices ,vis , variance across environments (EV) , Eberhart and Russel (ER) , Finlay and Wilkinson (FW) and Shukla (SH). Analysis of variance exhibited significant differences between genotypes at 1% for number of days to 75% heading, number of grains per spike, 1000 grains weight, grain yield and protein and dry glutein percentage at both sites and for two seasons and maturity in 2009 for both sites and number of spikes in m2 in Mosul and Arbil for 2010 season. Combine analysis showed highly significant differences between genotypes and genotypes X environments interaction for all studied traits except grain yield. Rwaida the local variety was earlier in heading and maturity of the two sites in 2009 and also in the environments average and the genotype POPP-TAHAR was superior for grain yield where it gave 1650.8 and 2352.8 kg /donum in Mosul site for two seasons, while in Arbil site in 2009 2-LIRON genotype was superior and gave 2585.9 kg /donum and in 2010 season the SN64/EER genotype was superior and gave 3202.5 kg /donun. LIRON genotype was in first rank by FW, ER indices and 1-LIRON ranked first by EV and SH and 1715/CENT came in second rank for 1000 seed weight and grain yield by EV and SH and ranked eleventh by FW and ER. | ||
