Glutenins of the 175 F 5 plant lines originated from
Triticum aestivum L (+)
Agropyron elongatum, together with SDS sedimentation
values of some of these plants were analyzed in the present work. The hybrids showed 10 different electrophoretic patterns of high molecular weight glutenin subunits (HMW-GS) composition. Six subunits, such as 1Ax1,1 Ax2 *,1Bx13,1By16,1By8 and 1Dx5 with 1By8 and 1By16 having the same mobility with those from A. elongatum, and three allelic combinations (1Bx13+1By16,1Bx7+1By8 and 1Dx5+1Dy12) occurred in the hybrids, which did not exist in the parent common wheat Jinan177. SDS sedimentation values of hybrid plant lines varied in a broad range. Some hybrids showed a distinctly higher SDS sedimentation than Jinan177. The results above indicated we can transfer the good-quality character of the wild plants into common wheat and create germplasms with different subunits and subunit combinations through somatic hybridization. It opens a new way for wheat quality breeding.
