陆地棉 光敏雄性不育 基因控制 隐性性状
2024/4/16
陆地棉光敏雄性不育系中9106是在中040029的后代中发现的突变体，它在长日照（河南安阳）条件下表现为彻底的雄性不育。以陆地棉乐土603、TM-1和海岛棉海7124为父本分别配置F2杂交组合发现中9106的雄性不育性状是受一对核基因控制的隐性性状。利用以全基因组测序为基础的分离群体群分法和以中9106×TM-1的F2群体进行的图位克隆，将中9106的雄性不育基因定位在D12染色体上QZD84和Q...
为了了解美国梾木花粉活力及萌发特性,采用扫描电镜技术和方差分析对13个美国梾木无性系花粉形态进行观测,并采用荧光显微技术和TTC染色法对无性系2号花粉萌发特性及花粉活力进行观察。结果显示：(1)不同无性系间花粉大小差异不显著,但外壁纹饰差异较大,极面沟距的变异系数最高且遗传最为稳定。(2)花序开花率为75%时花粉活力最高,整花4°C条件下短期保存花粉活力较高。(3)授粉后,多数花粉可在柱头上正常萌...
利用筛选的11条ISSR引物对从我国柑橘主产区和国外收集的135株叶点霉属真菌菌株进行扩增,扩增产物进行凝胶电泳,扩增图谱用NTSYS-pc2.10软件进行群体聚类分析。结果显示,共扩增出116个DNA条带,其中多态性位点为112个,多态率为96.55%;平均每个引物可以扩增出10.55个条带,扩增产物大小在250~3 000 bp。聚类分析显示,中国柑橘叶点霉属真菌可以分为4个种,即P. cit...
