Prospects of creating Indian dwarf wheat varieties Triticum sphaerococcum Perciv. based on samples endemic to the Hindustan peninsula

Published on

Pre-breeding study of five spring samples of Triticum
(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
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 of
T.sphaerococcum, was crossed
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.
