Wheat tightly related species contain abundants of disease, stress and insect resistant genes, which are excellent for wheat breeding. The excellent genes transferring to common wheat through distant hybridization, and the creation of heterochromatin systems such as double diploid or partial double diploid, addition line, substitution line and translocation line that contain genes of wheat tightly related species, are important ways for studying species chromosome behavior and evolution, and gene mapping. It also broadens the genetic basis of common wheat for diseases and pests resistance, and provides an important material basis for yield increase and quality improvement.
The Dryland Farming Institute of Hebei Academy of agriculture and Forestry Sciences has been engaged in the innovation of winter wheat germplasm for drought resistance, water-saving, high-yield and quality, and new varieties breeding. Main research programs on winter wheat include: conventional cross breeding, mutation breeding, distant hybridization, heterosis utilization and molecular marker assisted selection. New lines or materials have been created between species and genus such as common wheat and Thinopyrum elongatum, common wheat and triticale, common wheat and Thinopyrum Triticum.
We would like to cooperate with research institutes and scientists from oversea countries to conduct joint research. The objectives are to exchange germplasms of common wheat and its close related species, to study its cell biology and molecular biology and analyze its mechanism for stress resistance and high-yield, to develop distant hybridization materials or varieties that are both stress resistant and high-yield that without adverse linkage.
