InDel Marker Based Estimation of Multi-Gene Allele Contribution and Genetic Variations for Grain Size and Weight in Rice (Oryza sativa L.)
Insertion/Deletion (InDel) markers genetic variation multi-gene allele contributions rice (Oryza sativa L.), grain size and weight rice germplasm
2023/8/9
The market success of any rice cultivar is exceedingly dependent on its grain appearance, as well as its grain yield, which define its demand by consumers as well as growers. The present study was und...
Identification of a new molecular marker C2-25 linked to the Fusarium oxysporum f.sp. radicis-lycopersici resistance Frl gene in tomato

Fusarium oxysporum Schlecht. f.sp. radicis-lycopersici Jarvis & Schoemaker (FORL) is a saprophytic fungus, responsible for the fusarium crown and root rot disease in tomato (Solanum lycopersicum L.). ...
The Inheritance and Identification of RAPD Marker on Fruit Flesh Color in Loquat
breeding single dominant gene
2009/7/6
To understand the mode of flesh color inheritance in loquats (Eriobotrya japonica), segregation of flesh color (yellowish orange vs. whitish yellow) was investigated in 1,643 F1 progenies derived from...
Assessment on Evaluating Parameters of Rice Core Collections Constructed by Genotypic Values and Molecular Marker Information
core collection genotypic value molecular marker information
2008/12/11
Eleven evaluating parameters for rice core collection were assessed based on genotypic values and molecular marker information. Monte Carlo simulation combined with mixed linear model was used to elim...

Root-knot nematode [Meloidogyne incognita (Kofoid and White) Chitwood] is a major pest on cotton (Gossypium hirsutum L.) across the U. S. Cotton Belt. DNA markers that enable markerassisted selection ...
小麦SSR标记的发展及应用Microsatellite Marker Development and Applications in Wheat Genetics and Breeding
小麦 微卫星 分子标记 遗传图谱 遗传多样性
2007/12/30
摘要微卫星是以1～6个碱基为基本单元的串联重复序列，由于具有共显性、多态性高和容易用PCR方法检测等特点，是非常有用的遗传标记。在小麦中，SSR标记已广泛应用于遗传图谱的构建、遗传多样性、品种及基因型鉴定、目的基因，以及QTL的标记和标记辅助选择育种。

小麦异交群体连续歧化选择的RAPD分析RAPD Marker Analysis of Continuous Divergent Selection in Cross-Bred Population of Wheat (Triticum aestivum L.)
小麦异交群体 数量性状 遗传距离
2007/12/30
摘要利用太谷核不育基因构建的遗传变异丰富的基础群体DNS2，进行了连续5轮歧化选择。本论文从不同的世代中，选择了10个子群体进行RAPD分析。采用7个引物扩增出116个位点，从基因频率和表型带两个角度的分析都表明，群体具有丰富的遗传变异。整个群体总的多态位点百分率达88.79，总杂合度为0.3143。子群体内（间）遗传距离的结果显示：子群体内的遗传差异小于子群体间的遗传差异；各选择子群体与未选群体...
