A New Morphologic Marker for Chromosomes of the Fourth Homeologous Group of Triticinae

Cytology and Genetics 2001, v 35, number 1, 28-33

The character “hairy leaf sheath” was studied in two groups of introgressive common wheat lines. The first group involves lines containing genetic material of Aegilops sharonensis, the second one includes lines with chromatin of Triticum miguschovae. The gene controlling hairy leaf sheath, Hs, was located by us on chromosomes 4S^l (Ae. sharonensis) and 4D (T. miguschovae) due to its joint transfer with b -Amy-S^l1, b -Amy-D1, Acph-S^l1 and Acph-D1 genes situated on 4S^l and 4D chromosomes. The possibility to use the identified gene as a morphological marker for these chromosomes was shown.
