大豆是世界上最重要的油料作物之一，也是豆制食品加工业的重要原料。解析大豆产量和品质调控的遗传机制和关键基因，对于通过分子设计育种培育高产优质大豆新品种具有重要意义。大豆产量和品质相关农艺性状大部分是复杂性状，受一因多效和遗传连锁的影响，性状间呈现耦合性相关。挖掘协同调控产量和品质相关性状的关键基因和解析重要农艺性状耦合的遗传网络，可以为培育高产优质大豆品种提供重要理论基础。以往的研究往往针对大豆单...
Genotypic and Environmental Variation of Lag Period of Pod Growth in Soybean
Lag period Photoperiod Pod growth Soybean
2009/7/29
Pod growth in soybean (Glycine max (L.) Merr.) begins several days after flower opening, compared with more immediate growth in other beans. We investigated the relationship between genotype, raceme ...
Characteristics of Growth and Yield Formation in the Improved Genotype of Supernodulating Soybean (Glycine max L. Merr.)
Genotype Growth Nitrogen fixation Root nodule Soybean (Glycine max L. Merr.) Supernodulation Yield
2009/7/29
Most of the supernodulating soybean lines were agronomically inferior to conventional genotypes. Our previous tests with ‘En6500’, a supernodulating mutant derived from a variety ‘Enrei’, revealed tha...
NO and N2O Emissions from Fields in the Different Nodulated Genotypes of Soybean
Nitrous oxide Nitric oxide Root nodule Sakukei 4 Soybean
2009/7/8
We examined the influence of root nodules of soybean on the emission of NO and N2O, using three genotypes that were different in nodulating abilities, i.e., normal nodulating cv. ‘Enrei’, super-nodul...

Fifty-four accessions of local soybean strains were collected from villages in the western part of the Shikoku Mountains and examined for morphological traits associated with growth, yield, seed size ...
应用重组自交系群体定位大豆根重QTLMapping QTLs of Soybean Root Weight With RIL Population NJRIKY
大豆根重 QTL定位 重组自交系(RIL) 分子遗传图谱
2008/1/8
摘要
应用构建的NJRIKY(科丰1号×1138-2)大豆重组自交家系群体，对大豆根重QTL进行8次重复的随机区组分析；以该群体所构成的遗传连锁图谱为基础，采用复合区间作图法（Cartographer V. 1.21）检测到3个与根重有关的QTL位于连锁群N3-B1和N6-C2上。其中rw1在N3-B1的端距离是66.31cM，位于A520T～ACCCAGO5 区间，rw2和rw3分别在N6...
利用RACE技术扩增大豆抗病基因同源cDNA 5′末端序列Amplification of 5′ cDNA End of a Disease Resistance Gene Homolog Using RACE System from Soybean
5′-RACE 抗病基因同源序列 大豆
2007/12/31
摘要利用抗病基因保守序列筛选大豆cDNA文库，获得一抗病基因同源cDNA片段，命名为KR3-1。根据KR3-1设计两个基因特异引物（GSP 和 NGSP），分别与通用引物(UPM)和巢式通用引物（NUP）共同扩增，成功地克隆到了该基因的5′末端序列。该扩增片段长447 bp，与已知序列重叠部分为129 bp。
