Transfer of Useful Germplasm from Leymus racemosus Lam. to Common Wheat Ⅶ. Development and Identification of A Triticum aestivum-Leymus racemosus Isochromosome Addition Line with Scab Resistance
Two scab resistant Triticum aestivum-Leymus racemosus isochromosome addition lines, 93G51-9 and 93G52-8, involving a pair of isochromosomes derived from the self-pollinated progenies of diosomic addition line (Lr. 7) were selected and identified by meiotic configuration analysis combined with Giemsa C-banding. The developed isochromosome addition lines with some scab-resistance are valuable stocks for transferring scab resistance genes into common wheat because of the high pairing frequency of the two arms ...
