[Chromosomal localization of a gamete-killing gene in a wheat line]. / Khromosomnaia lokalizatsiia gametotsidnogo gena v linii pshenitsy.

Monosomic analysis revealed that a gametocidal gene in a common wheat line derivative from Aegilops speltoides is located on chromosome 2B. This gene induces semisterility, low level of chromosome breaks, shriveled seeds, and endosperm degeneration. The obtained data indicate that the localized gene is allelic to well known gametocidal genes Gc1a and Gc1b.
