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...
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.)

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...
