Abstract

The new cereal, PRIMARY TRITIPYRUM LINES, is an artificial hexaploeid wheat (2n=6x=42, AABBEbEb) from crossing between Triticum durum (2n=4x=28, AABB) and Thinopyrum bessarabicum (2n=2x=14, EbEb) species. In this study the salt tolerant potencial of new PRIMARY TRITIPYRUM LINES for NaCl (0, 100, 200 Mm) in an hydroponic experiment was studied in a completely randomized split plot design with three replication. The salinity stress NaCl was considered as main plots with 3 levels and the plant materials consisting of three primary tritipyrum [lines: (Ka/b, La/b, St/b)], the F4, F5, F6 generations of a combined primary tritipyrum [line: (Ka/b)(Cr/b)], one durum wheat (cv: Creso)] and one modern promising triticale (line: Ma45) were considered as sub plots with 8 levels. spike length (cm), grain per leading spike and its spikelets, fertile florets per leading spike, grain weight per leading spike and its spikelets, 1000-grain weight per plant (gr), grain yield per plant (gr), biologic yield per plant (gr) and harvest index per unit were measured or counted. The results showed a significant difference (a=5%) between lines and cultivars for the mean of all characters in non-NaCl stress and highly significant (a=1%) for NaCl stress. Although all traits were reduced by increasing the salt stress from 0 to 200 mM but for PRIMARY TRITIPYRUM LINES the reduction at 200 mM was very low in comparison to controls (durum wheat cultivar and promising triticale line). The combined primary tritipyrum line (Ka/b) (Cr/b), F6 had maximum harvest index, biological yield and grain yield per plant in 100 & 2oo mM NaCl stress. It highly can be concluded that Ttritipyrum lines, particularly, this line has salt tolerant potential for using as pasture and forage in saline soils.
