Blast disease, caused by the Magnaporthe oryzae/grisea species complex, occurs in a wide range of wild and cultivated gramineous plant species including rice, wheat and barley. We inoculated a collection of cultivated (Hordeum vulgare ssp. vulgare L.) and wild (ssp. spontaneum) barley accessions with M. oryzae Oryza pathotype (MoO), Triticum pathotype (MoT) and Pennisetum pathotype (MsP) to quantify...
The acreage of submerged direct-sown cultivation of Oryza sativa is gradually increasing in China because of the constantly decreasing number of laborers in rural areas. Identifying favorable alleles for seedling anoxic tolerance (SAT) is necessary for improving cultivars suitable for submerged direct-sown rice cultivation. In this study, we used two populations to detect quantitative trait loci (QTLs)...
Sugarcane orange rust, caused by the fungus Puccinia kuehnii, is a serious disease of sugarcane. The most effective strategy to combat the disease is to develop resistant cultivars. Phenotypic screening for resistance is laborious, and breeders would benefit from molecular markers linked to the trait. The objective of this research was to identify, via association mapping, markers linked to resistance...
The advancements in genotyping have opened new approaches for identification and precise mapping of quantitative trait loci (QTLs) in plants, particularly by combining linkage and association mapping (AM) analysis. In this study, a combination of linkage and the AM approach was used to identify and authenticate putative QTLs associated with black tea quality traits and percent relative water content...
The outcrossing traits in rice affect the yield of hybrid rice seed production. In this study, 30 quantitative trait loci (QTLs) were detected in a natural population composed of 522 accessions by using a mixed linear model for the four outcrossing-related traits in 2017 and 2018. We detected 3, 4, 9 and 14 QTLs for flag leaf length (FLL), flag leaf width (FLW), flag leaf angle (FLA) and panicle neck...
