Identification of a wheat-Thinopyrum intermedium substitution line as revealed by GISH, FISH and SSR
Wide hybridization between wheat (Triticum aestivum L.) and wild relatives is an important means for increasing the amount of genetic diversity available to wheat.
Wheat leaf rust caused by Puccinia triticina is one of the important diseases of wheat in China.It can cause a pandemic in a short time and cause yield losses of 5％ to 45％ or more on susceptible wheat
Comparison on agronomic traits and qualitative characters between powdery mildew resistant and susce
Yangmai 18, a new soft wheat variety with high powdery mildew resistance, was developed following the rolling convergent backcross procedure with the resistant donor as T6VS.6AL translocation that con
Zebularine is a cytidine analogue which has an ability to cause DNA demethylation in plants and many other organisms which resulted in gene reactivation and chromosome structural variations.
Oligodeoxynucleotides (oligos hereafter) are short (20～50 nt) and single stand DNA molecules which are widely used in genetic research.The use of specific oligos as probes makes FISH more rapidly and
QTL analysis of flour falling number using recombinant inbred lines derived from strong gluten wheat
Flour falling number (FN) is an important trait because of not only relating with pre-harvest sprouting (PHS) tolerance but processing quality.Waxy wheat usually has low flour falling number (FN) with
Cytosine methylation is a well recognized epigenetic mark.Here, the methylation status of a salinity tolerant (cv.SR3, derived from a somatic hybridization event) and its progenitor parent (cv.JN177)

小麦穗部性状是与产量关系密切的重要农艺性状.本研究以Batavia和Erine为亲本构建的DH群体为材料,利用SSR标记和DArT标记对穗长进行数量性状进行QTL分析.构建的遗传连锁图谱由77个SSR标记和711个DArT标记组成,图谱全长1813.3 cM,标记间的平均遗传距离为2.301 cM.

High molecular weight glutenin subunits (HMW-GSs) are significant in the determination of grain processing quality.However, the diversity and variations of HMW-GSs are relatively low in bread wheat.
Chromosome translocation is an important driving force in the evolutionary process and crop breeding that can immediately change gene linkages and gene expression.
