Abstract

Although the non-Iranian primary tritipyrum lines (NIPTLs) have been produce and have shown potential to be a new slat tolerant cereal, however, have a few undesirable traits such as brittle rachis, keep in tiller production and late maturity. In order to remove these traits, the crossing of NIPTLs with Iranian bread wheat cultivars led to new recombinant Iranian secondary tritipyrum lines. In this study the 13 non-Iranian primary tritipyrum lines (NIPTLs: 2n = 6x = 42; AABBEbEb) and Iranian secondary tritipyrum lines (ISTL: F6-F7; 2n=6x=42, AABBD(1-6)"Eb (1-6)"), 6 Iranian bread wheat cultivars and 1 promising triticale line were evaluated at two research centers using an alpha lattice design with two replications under normal (1 dS m-1) and salinity stress ( 12dS m-1) conditions during growing seasons of 2014-2016 at Kerman province of Iran. The results indicated grain yield was strongly affected by salinity with reduction ratio of 11. 06, 9. 37, 4. 30, 4. 98, 7. 98, 12. 58, in Iranian chromosomally recombinant secondary individuals tritipyrum plants obtained from crosses such as (Cathlicum × Ma/b), (Falat× Ma/b), {Omid × (Ka/b)(Cr/b)}, {Niknejad × (Ka/b)(Cr/b)}, (Shotordandan × ka/b), (Roushan × Az/b), respectively, in comparison with Non Iranian Primay Ttritipyrum Lines (NIPRLs) (3. 48), Iranian bread wheat cultivars (19. 90) and promising triticale line (15. 87) The evaluation of Stress tolerance indices showed that STI could effectively be used for screening of salinity tolerant genotypes because it had the highest correlation coefficients with grain yield. The (Cr/b) × (Ka/b) line of NIPTLs and the lines obtained from Niknejad × (Ka/b)(Cr/b) and Omid × (Ka/b)(Cr/b) crosses showed the highest average breeding value which will be suitable for breeding programs of ISTLs lines with high yield potential in saline soils and brachish waters.
