Simultaneous selection for resistance to five bacterial, fungal, and viral diseases in three Andean × Middle American inter-gene pool common bean populations
Numerous bacterial, fungal, and viral diseases cause severe damage on roots, foliage, stem, pods, and seeds, resulting in yield and quality losses in common bean (Phaseolus vulgaris L.) worldwide. Cultivars with resistance ...
Molecular mapping of a new source of Fusarium wilt resistance in tetraploid cotton (Gossypium hirsutum L.)
Fusarium wilt (FW) disease is an economically important disease of cotton worldwide and a major cause of crop losses in Australia and many other cotton-producing countries. Symptoms include wilting, vascular browning and ...
Breeding disease-resistant wheats for tropical highlands and lowlands
Wheat is grown on about 10 million ha in the tropical highlands and lowlands of the world, where it is an important food source. Many farmers in these areas work under subsistence conditions. Wheat diseases in tropical ...
Molecular mapping as a tool for pre-emptive breeding for resistance to the exotic barley pathogen, Puccinia striiformis f. sp. hordei
Barley stripe rust (BSR), caused by Puccinia striiformis f. sp. hordei, has been a major disease problem to the barley industry worldwide that has not, to date, been detected in Australia. This paper describes the mapping ...
Identification and validation of a common stem rust resistance locus in two bi-parental populations
(Frontiers; Frontiers Media, 2018)
Races belonging to Ug99 lineage of stem rust fungus Puccinia graminis f. sp. tritici (Pgt) continue to pose a threat to wheat (Triticum aestivum L.) production in various African countries. Growing resistant varieties is ...
Microsatellite mapping identifies TTKST-effective stem rust resistance gene in wheat cultivars VL404 and Janz
Wheat cultivar VL404 carries seedling resistance to Puccinia graminis f. sp. tritici pathotype TTKST. Monogenic segregation for seedling resistance was observed in a VL404/WL711 recombinant inbred line population and the ...
Progress of wheat breeding in China and the future perspective
During the last ten years, Chinese wheat breeding has mainly made progresses in three aspects, i.e., (1) two sets of cultivars with high yielding potential, improved quality, and multi-resistance to various diseases were ...
Suppression expression of resistance to stripe rust in synthetic hexaploid wheat (Triticum turgidum x T. tauschii)
Some 74 hexaploid wheats, synthesized by either crossing resistant Triticum turgidum var. durum [T. durum] with susceptible/intermediate T. tauschii [Aegilops squarrosa] or susceptible/intermediate T. turgidum with resistant ...
