Pre-breeding study of five spring samples of Triticum
sphaerococcum (Perciv.) endemic to the Hindustan
Peninsula was carried out in the Middle Volga Region of
Russia in 2011–2018. The study demonstrated that all the
samples were highly susceptible to powdery mildew
disease, with infection up to 90% on infected leaf surface.
Maximum yield was observed in sample k-33748 of T.
sphaerococcum and did not exceed 2.25 t/ha as compared
to 4.83 t/ha yield of the standard bread wheat variety
Simbircit. Sample k-45738 ofT.sphaerococcum, was crossed
with T. aestivum and the wheat lines with significantly high
yield and 1000-grain weight as well as better powdery
mildew resistance as compared to Indian dwarf wheat were
obtained. The selected lines resembles T. sphaerococcum
with the spherical grain shape, the ratio between length
and width of grain characteristics and other species-specific
traits, such as compact head, short erect leaves, and short
firm stem.
