In the dry area, five of the non-translocated cultivars performed as well as the translocated ones. [...]it could be concluded that translocation had no obvious positive effect on yield. According to literature the presence of the translocation offers to the host cultivar high yield potential (Kim et al., 2004; Xynias et al., 2007), mainly due to increased seed weight and production under drought conditions (Ehdaie et al., 2003). Acheron, Elissavet and Orfeas) whereas the other six cultivars, were lacking the specific translocation (Xynias et al., 2006; Peros et al., 2015). b. Method The experiments were established for three successive years 2015-16 to 2017-18 in the main Farm of the School of Agricultural Sciences, in Florina (40°46' N, 21°22'E, 707 m asl), representing a cold and wet environment and in the main farm of Plant Breeding and Genetic Resources Institute, Hellenic Agricultural Organization-"Demeter" in Thermi (40°32' N, 23°00'E, 15 m asl), representing a marginal dry environment Table 1). Except in the effect of the environment which accounted 11.6% of the yield total sum of squares - TSS (as compared to 6.9% and 58% for genotypes and genotype x environment interaction - GEI effects respectively), the values on the other traits were the ones expected. [...]the environment accounted for 93.6% of the earliness to heading TSS (as compared to 1.2 and 4.4% for genotypes and GEI effects respectively), 84.4% of the plant height at maturity TSS (as compared to 7.0% and 3.5% for genotypes and GEI effects respectively) and 73.3% of the 1000 kernel weight TSS (as compared to 4.7 and 11.6% for genotypes and GEI effects respectively).
