A promising area in wheat breeding is use of genepool containing new valuable genes,
introgressed into wheat from its wild relatives and cultivated species of other taxonomic
groups, as the initial material. Due to this approach a commercial variety of spring bread
wheat and new advanced lines were developed by breeding programs in 2000-2009. The
initial material involved in breeding of the above comprised immune lines of bread wheat
variety Saratovskaya 29 and alloplasmic recombinant lines of bread wheat, which were
produced by Institute of Cytology and Genetics using chromosome engineering methods.
Saratovskaya 29 immune lines contain genes responsible for powdery mildew and
leaf rust resistance and high grain quality being incorporated from synthetic amphiploid
T. timopheevii x Ae. tauschii (AtAtGGDD). These lines by now have proved to be efficiently
used as donors of these genes in breeding programs. For example, a cross between
bread wheat genotype Rang (Sweden) and one of Saratovskaya 29 immune lines (Rang/
Saratovskaya 29 ВС5) resulted in moderately late variety Pamyaty Maystrenko following
a relevant advanded yiled trial (2007-2009).
Irrespective of growing conditions this variety is characterized by high field resistance
to powdery mildew and leaf rust. Initial symptoms of of leaf rust and powdery mildew
were found to manifest significantly later on variety Pamyaty Maytrenko if compared
with susceptible moderately late check Omskaya 18. Protein content of variety Pamyaty
Maystrenko is higher by 2, 53% than that of the check whereas gluten content – by 5, 2%,
flour strength – by 197 a.u., loaf volume – by 50 cm3. The grain yield of this variety is the
same with that of the check Omskaya 18. In 2009 spring wheat Pamyaty Maystrenko was
submitted to the Russian State Yield Trial. Alloplasmic recombinant lines of bread wheat
were identified from BC3-BC4 progenies of barley-wheat hybrids 1) H.vulgare (Nepolegayuschiy)
x T.aestivum (Saratovskaya 29) and 2) H.vulgare (line 319) x T.aestivum
(Saratovskaya 29). The first hybrid combination was backcrossed by bread wheat Mironovskaya
808 (twice) and Saratovskaya 29 (once), while the second combination was
backcrossed by bread wheats Saratovskaya 29 (thrice) and Ulyanovka (once). Alloplasmic
recombinant lines characterized by early maturity and high tillering were included in the
breeding program. A promising moderately early variety Lutescens 311/00-22 was produced
from the crossing of the alloplasmic recombinant line L-17D with a CIMMYT line
of spring bread wheat Kom 37.
