Autor: Njau, P. Autor: Wanyera, R. Aspects of migration, mutation, recombination and selection in the pathogen have led to previously deployed stem rust resistance genes being ineffective.

The orbital velocity class 11th plant stem rust responses were scored using the modified Cobb? The F lines of population s exhibiting qualitative variation were grouped as homozygous resistant HRsegregating Seg and homozygous susceptible HS. Chi square analysis revealed that the segregation data in the parent KSL-2 did not deviate significantly from the single gene model suggesting which race genes are dominant the resistance to stem rust is conditioned by a single dominant gene.

The families from the KSL-2 and KSL-3 crosses also segregated for the presence of the pseudo black chaff implying that theSr2 gene could be present in the background of these wheat parents. The superior transgressive segregants identified in these crosses will be used in breeding. The user is free to download, print, store and share this work.
