QTL Analysis and Nested Association Mapping for Adult Plant Resistance to Powdery Mildew in Two Bread Wheat Populations
CIMMYT wheat (Triticum aestivum L.) lines Francolin#1 and Quaiu#3 displayed effective and stable adult plant resistance (APR) to Chinese Blumeria graminis f. sp. tritici isolates in the field. To elucidate their genetic basis of resistance, two recombinant inbred line (RIL) populations of their crosses with Avocet, the susceptible parent, were phenotyped in Zhengzhou and Shangqiu in the 2014-20...
متن کاملmlo‐based powdery mildew resistance in hexaploid bread wheat generated by a non‐transgenic TILLING approach
Wheat is one of the most widely grown cereal crops in the world and is an important food grain source for humans. However, wheat yields can be reduced by many abiotic and biotic stress factors, including powdery mildew disease caused by Blumeria graminis f.sp. tritici (Bgt). Generating resistant varieties is thus a major effort in plant breeding. Here, we took advantage of the non-transgenic Ta...
متن کاملAllelic series of four powdery mildew resistance genes at the Pm3 locus in hexaploid bread wheat.
At the Pm3 locus in hexaploid wheat (Triticum aestivum), 10 alleles conferring race-specific resistance to powdery mildew (Blumeria graminis f. sp. tritici) are known. A cluster of genes encoding coiled-coil-nucleotide-binding site-leucine-rich repeat proteins spans the Pm3 locus on wheat chromosome 1A, and one member of this gene family has recently been identified as the Pm3b resistance gene....

متن کاملThe Lr34 adult plant rust resistance gene provides seedling resistance in durum wheat without senescence
The hexaploid wheat (Triticum aestivum) adult plant resistance gene, Lr34/Yr18/Sr57/Pm38/Ltn1, provides broad-spectrum resistance to wheat leaf rust (Lr34), stripe rust (Yr18), stem rust (Sr57) and powdery mildew (Pm38) pathogens, and has remained effective in wheat crops for many decades. The partial resistance provided by this gene is only apparent in adult plants and not effective in field-g...
