Physical Location of New PCR-Based Markers and Powdery Mildew Resistance Gene(s) on Rye ( L.) Chromosome 4 Using 4R Dissection Lines.

Rye ( L.) 4R chromosome contains elite genes that are applicable for wheat ( L.) cultivar improvement.

Molecular mapping and genetic analysis of a QTL controlling spike formation rate and tiller number in wheat.

Spike formation rate (SR), which is based on maximum tiller number per unit area and spike number per unit area, is an important yield-related trait in wheat. Increasing the spike formation rate reduces growth competition and wastage of photosynthate from ineffective tillers. Unfortunately, research studies involving quantitative trait locus (QTL) mapping for wheat spike formation rate are limited.
