Identification of candidate genes for key fibre-related QTLs and derivation of favourable alleles in Gossypium hirsutum recombinant inbred lines with G. barbadense introgressions
海岛棉 基因组组分 遗传作图群体
2024/5/17
该研究以渗入了海岛棉基因组组分的优质种质鲁原343为亲本，构建了包含239个重组自交系的遗传作图群体，利用SLAF标签构建了高密度遗传图谱，结合7个环境的表型数据，共鉴定104个纤维品质和产量性状QTLs，其中66个QTL共定位于19个QTL簇中。该研究团队通过进一步对鲁原343进行全基因组深度测序，解析鲁原343的遗传组成及其对纤维相关性状的遗传贡献，发现来自G. hirsutum races（...
Comparative evaluation of maize inbred lines (zea mays l.) according to dus testing using morphological, physiological and molecular markers
DUS Inbred Lines Maize Markers Genetic Distance Diversity
2013/3/5
A major challenge facing those involved in the testing of new plant varieties for Distinctness, Uniformity and Stability (DUS) is the need to compare them against all those of 'common knowledge'. A se...
The genotoxic potential of two heavy metals in inbred lines of maize (Zea mays L.)
Zea mays inbreds mercury cadmium chromosomal anomalies
2010/3/17
The genotoxic effects of 2 heavy metals (mercury chloride and cadmium chloride) on the gametic cells of 6 inbred lines of maize were tested in terms of cytological abnormalities. Meiosis was normal un...
Mapping of QTLs Controlling Carbon Isotope Discrimination in the Photosynthetic System using Recombinant Inbred Lines Derived from a Cross between Two Different Rice (Oryza sativa L.) Cultivars
Carbon isotope discrimination (Δ) Photosynthesis Quantitative trait locus (QTL) Rice (Oryza sativa L.)
2009/7/24
