Comment
Allelic variation at the Ch2 locus is suggested in 373 and 709. Prelude, Reward and Red Bobs are exceptional in producing severe symptoms and death at an early stage. Konosu 25 may carry a weak allele (709). Different alleles in C306 (strong) and Sonalika (medium) were suggested in 501.
Hexaploid stock: T. vavilovi.
