Genetic Analysis and Molecular Mapping of a Leaf Rust Resistance Gene in the Wheat Line 19HRWSN-129
gene mapping molecular marker SSR wheat leaf rust
2016/4/5
The wheat (Triticum aestivum L.) line 19HRWSN-129 from CIMMYT showed resistance to the major Puccinia
triticina (Pt) races collected in China. A 144 F2:3 population was generated by crossing the res...
Genetic analysis and molecular mapping of leaf rust resistance genes in the wheat line 5R618
gene postulation genetic mapping molecular marker wheat leaf rust
2014/12/1
The wheat (Triticum aestivum L.) line 5R618, bred at the China Agricultural University, is resistant in the seedling stage to the majority of the current Chinese pathotypes of wheat leaf rust (Puccini...
Genetic analysis of preharvest sprouting tolerance in bread wheat (Triticum aestivum L. emend. Thell.)
Preharvest sprouting ermination index iallel cross, enetic parameters read wheat editerranean region
2011/3/22
Rains during grain ripening in wheat (Triticum aestivum L.) can cause preharvest sprouting (PHS), which drastically affects the grain yield and the baking quality of flour. In the present study, to sc...
Genetic analysis of some physical properties of bread wheat grain (Triticum aestivum L. em Thell)
Single kernel characteristics diallel cross regression and path coefficient analysis
2010/2/24
Very little information exists on the relative genetic architecture of the grain physical properties of wheat. The physical properties of grain have a direct or indirect influence on the milling and b...
Genetic Analysis of Tea Gray Blight Resistance in Tea Plants
epistatic effect genotype phenotype
2009/9/10
Tea gray blight caused by Pestalotiopsis longiseta SPEGAZZINI is a severe disease in tea fields in Japan. The resistance of tea plants to the disease was found to be controlled by 2 independent domina...
Production of Doubled Haploid Lines for Genetic Analysis of Useful Characters of Malting Barley
Genetic analysis Doubled haploid lines Barley Molecular marker H. bulbosum L.
2009/7/8
To develop a DNA marker assisted selection system for lines with recessive resistance gene to all races of barley yellow mosaic virus (BaYMV), we produced doubled haploid lines (DHLs) of barley (Horde...
Varietal Difference and Genetic Analysis of Adventitious Root Formation at the Soil Surface during Flooding in Maize and Teosinte Seedlings
Adventitious root Genetic resource Maize Seedling
2009/7/8
Adventitious root-forming (ARF) ability, at the soil surface, is most important for adaptation of the plant to soil flooding or waterlogging. We evaluated the ARF ability of maize and teosinte seedlin...

2009/1/7
The objective of this study was to estimate main genetic effects including digenic non-allelic epistasis for yield and starch content in grain by generation mean analysis performed in 9 maize populat...
摘要
以两个耐铝性不同的玉米自交系及它们的杂交和回交世代为材料，采用营养液培养方法，对玉米的耐铝性进行了遗传分析。结果表明，根系相对生物量具有较高的的遗传变异，其广义遗传率高达78.6%。但其狭义遗传率仅为15.4%，说明其遗传方式以显性效应为主。相反，地上部相对生物量具有相对较高的狭义遗传率（43.1%），其遗传方式以加性效应为主。在0.1m mol/L Al3+ 胁迫条件下，根系总的和活跃的...
