Four major wheat cultivars of Bangladesh viz., Akbar, Ananda, Kanchan, Sonalika; an Advance line, a Synthetic wheat and all exotic material, Atlas 66 were evaluated for seed protein, contents and, pollen viability of Synthetic wheat. Seed protein, content in, these materials varied significantly. Synthetic whet and atlas 66 contained 26.0 and 21.2% seed protein, respectively, while the other materials contained 11.8-12.9%. The Synthetic wheat did not shed pollen at low temperatures (10-12 centigrade) but did at higher temperatures (20-35 centigrade). The wheat cultivars and the Advance line were crossed with Synthetic wheat and Atlas 66. The F1 seeds from all these crosses were intermediate to their parents with respect to seed protein, content and overall morphology. In both F1 and F2 generations, protein, content varied significantly among the different cross combinations. However, the F1 seeds from Atlas 66 group contained 15.1-15.9% protein, and in Synthetic wheat group the range of protein content was 17.3-19.4%. The F2 seeds possessed protein 18.8-19.8 and 18.9-23.0% for Atlas 66 and Synthetic wheat groups, respectively. The F2 seeds from both kinds of crosses showed wide variations it, this trait leading to assume the mode of action of seed protein, gene as additive. These materials call be utilized for further research to elevate the protein levels of wheat cultivars.
