Cultivar Agrus, possessing a chromosomal substitution, and cultivar Sunnan, possessing a translocation from Thinopyrum ponticum (= Agropyron elongatum, 2n = 10x) with leaf rust resistance gene Lr19 ag...
Recent Advances in Marker-Assisted Selection for Drought Tolerance in Pearl Millet
Drought Marker-assisted breeding Pennisetum glaucum QTL introgression lines QTL mapping
2009/7/24
Pearl millet [Pennisetum glaucum (L.) R. Br.] is the staple cereal of the hottest, driest areas of the tropics and subtropics. Drought stress is a regular occurrence in these regions, making stress to...
Molecular Marker Assisted Selection in Breeding for Resistance to Bacterial Wilt in Carnation (Dianthus caryophyllus L.)
backcross Burkholderia caryophylli QTL RAPD
2009/7/9
The availability of marker-assisted selection (MAS) using DNA markers close to QTLs of resistance to bacterial wilt in carnations (Dianthus caryophyllus L.) was examined. The STS-WG44 marker tightly l...
Breeding Rice Restorer Lines with High Resistance to Bacterial Blight by Using Molecular Marker-Assisted Selection
bacterial blight resistance gene pyramiding hybrid rice restorer line molecular marker-assisted
2009/1/7
Two bacterial blight (BB) resistance genes, Xa21 and Xa4, from IRBB24 were introduced into hybrid rice restorer line Mianhui 725, which is highly susceptible to BB, by using hybridization and molecula...
Lowering Grain Amylose Content in Backcross Offsprings of indica Rice Variety 057 by Molecular Marker-Assisted Selection
molecular marker-assisted selection indica rice amylose content grain quality
2009/1/7
To lower the amylose content (AC) of the indica rice restorer line 057 with high AC, backcrosses were made respectively by using four indica varieties (R367, 91499, Yanhui 559, Hui 527) as low AC don...
Marker-assisted Selection of ZmC4Ppc in Rice Breeding and Yield Trait Performances of Advanced Lines
rice Zea mays gene for phosphoenolpyruvate carboxylase primer design
2008/12/11
The full-length of intact Zea mays gene for phosphoenolpyruvate carboxylase gene (ZmC4Ppc) is 6 781 bp. The products of PCR for this gene were not clear with poor repeatability, resulting in that it w...

摘要
本研究以辽宁绒山羊、柴达木绒山羊和柴达木山羊3个群体共147只山羊为研究对象，运用PAGE和RAPD技术对山羊的体重、绒产量和绒细度3个性状进行了与标记基因关系的遗传分析，结果表明：EsD2-2型、LAPBB型和PA-32-2型分别为体重、绒产量和绒细度性状的优势标记基因型；可利用标记辅助预测的方法充分利用多基因座标记基因间的互作效应；在体重上，寻找到有显著选择效应的RAPD条带11...
