Comment
|
Extremely widespread, very few wheats lack this gene.
Allelic variation at the Ch2 locus was suggested {537,1000}. Prelude, Reward and Red Bobs were exceptional in producing severe symptoms and death at an early stage. Konosu 25 may carry a weak allele {1000}. Different alleles in C306 (strong) and Sonalika (medium) were suggested in {697}.
