QTL mapping of heading date and plant height in Barley cross “Azumamugi”דKanto Nakate Gold
To identify quantitative trait loci (QTLs) controlling heading date and plant height, ninety nine F13 recombinant inbred lines (RILs) derived from barley cultivars Azumamugi × Kanto Nakate Gold cross were evaluated. The field trails were conducted at randomized complete block design with two and three replications in 2004 and 2005, respectively. Significant differences and transgrassive segrega...
متن کاملOsMPH1 regulates plant height and improves grain yield in rice
Plant height is a major trait affecting yield potential in rice. Using a large-scale hybrid transcription factor approach, we identified the novel MYB-like transcription factor OsMPH1 (MYB-like gene of Plant Height 1), which is involved in the regulation of plant height in rice. Overexpression of OsMPH1 leads to increases of plant height and grain yield in rice, while knockdown of OsMPH1 leads ...
متن کاملA New QTL for Plant Height in Barley (Hordeum vulgare L.) Showing No Negative Effects on Grain Yield
INTRODUCTION Reducing plant height has played an important role in improving crop yields. The success of a breeding program relies on the source of dwarfing genes. For a dwarfing or semi-dwarfing gene to be successfully used in a breeding program, the gene should have minimal negative effects on yield and perform consistently in different environments. METHODS In this study, 182 doubled haplo...
متن کاملAnalysis of the epistatic and QTL×environments interaction effects of plant height in maize (Zea mays L.)
A genetic map containing 103 microsatellite loci and 200 F2 plants derived from the cross R15 × Ye478 were used for mapping of quantitative trait loci (QTL) in maize (Zea mays L.). QTLs were characterized in a population of 200 F2:4 lines, derived from selfing the F2 plants, and were evaluated with two replications in two environments. QTL mapping analysis of plant height was performed by using...
متن کاملZmGA3ox2, a candidate gene for a major QTL, qPH3.1, for plant height in maize.
Maize plant height is closely associated with biomass, lodging resistance and grain yield. Determining the genetic basis of plant height by characterizing and cloning plant height genes will guide the genetic improvement of crops. In this study, a quantitative trait locus (QTL) for plant height, qPH3.1, was identified on chromosome 3 using populations derived from a cross between Zong3 and its ...
