Barley yellow dwarf virus infection (BYDV) often results in substantial yield losses in susceptible cereal crops. Major symptoms of BYDV infection in cereals include plant dwarfing and colour changes of leaf blades along the vascular bundles, especially of leaf tips. A full understanding of physiological and molecular mechanisms contributing to resistance provides salient information for breeding...
Based on double pseudo-testcross theory, a population of 79 F1 clones, which was derived from a crossing of two tea cultivars using a Japanese tea cultivar “Fushun” (Camellia sinensis) as female parent and a Korean tea cultivar “Kemsull” (C. sinensis) as male parent, was applied to construct a genetic linkage map with different molecular markers. Previously, 143 random amplified polymorphism DNA (RAPD)...
Tobacco mosaic virus (TMV) caused serious loss in yield and quality of tobacco every year. It is a long-term goal to improve the tobacco resistance against TMV by tobacco breeding. N gene was the firstly reported TMV-resistant gene, which showed resistance against all Tobamoviruses except the Ob stain and belonged to the toll-interleukin-1 receptor/nucleotide-binding site/leucine-rich repeat class...
The adult plant leaf rust resistance gene Lr34 was introduced using marker assisted selection (MAS) into an Indian wheat cultivar HUW510. Lr34 is associated with enhanced resistance to spot blotch. However, this effect has not been validated previously via introgression from one genetic background into another using MAS. The donor parent was the CIMMYT breeding line Picaflor#1. The morphological marker...
