Studies in the Genetics of Triticum vavilovi Jakub

Abstract
Synopsis: Triticum vavilovi, a lesser known hexaploid wheat, was successfully crossed reciprocally with T. sphaero‐coccum and with 3 strains of T. vulgare to aid in determining its taxonomic status and genetic relationships. The F1 plants were comparatively normal in appearance and fertility. Most F2 plants had highly fertile pollen though sterility was observed in some. A few F2 plants of the sphaerococcum cross were highly to completely seed sterile. In general the data suggest that T. vavilovi is more closely related to T. vulgare than its superficial appearance might indicate.
