Background Haynaldia villosa (L.) Schur (syn. Dasypyrum villosum L. Candargy, 2n = 14, genome VV) is the tertiary gene pool of wheat, and thus a potential resource of genes for wheat improvement. Among other, wheat yellow mosaic (WYM) resistance gene Wss1 and a take-all resistance gene were identified on the short arm of chromosome 4 V (4VS) of H. villosa. We had obtained introgressions on 4VS chromosome...
Wheat yellow mosaic disease (WYM) became more serious in China in the recent years. Cultivation of resistant varieties is the major strategy for disease control. To identify WYM resistant genes in Chinese wheat cultivar ‘Yining Xiaomai’, a population of 106 recombinant inbred lines (RIL) from a cross between Yining Xiaomai and Zhen 9523 (WYM-susceptible) was generated. Phenotypic data of WYM resistance...
Plant height and spikelet density are important agronomic traits related to plant architecture and grain yield in wheat. The development of wheat mutants not only provided new genetic resources for wheat improvement, but also facilitated our understanding of the regulation of these traits at the molecular level. Here, we report the identification of a dwarf mutant with a compact spike. NAUH164, produced...
Fusarium head blight (FHB), also called wheat scab, is an important disease in warm and humid regions worldwide, which not only reduces crop yield and grain quality, but also is a major safety concern in food and feed production due to mycotoxin contamination. Growing wheat cultivars with FHB resistance is one of the most economical and effective means to control the disease. Chinese wheat...
