Resistance to soil-borne diseases of wheat: Contributions from the wheatgrasses Thinopyrum intermedium and Th. ponticum

摘要: Eyespot, Cephalosporium stripe, and common root rot are soil-borne diseases that damage the stem bases, vascular system, subcrown internodes,and roots of wheat. Resistance in wheat to these is insufficient prevent significant yield loss when disease severe. The wheatgrasses Thinopyrum intermedium Th. ponticum highly resistant diseases. Identification disease-resistant wheat-Thinopyrum partial amphiploids, chromosome addition, substitution, translocation lines makes them a valuable source resistance genes for breeding programs. Single chromosomes or segments containing can be transferred into produce genetic stocks afford better understanding control new resources improvement. eyespot was associated with homoeologous group 4 chromosomes, whereas stripe controlled b...
