简介：在引起线之中的基因差异和关系的调查是很重要的在引起节目的混合米饭便于父母选择。在这研究，我们与207简单顺序重复(SSR)和353单个核苷酸多型性(SNP)从国际瑞斯研究院描绘了168个混合米饭父母标记。1267SSR和706SNP等位基因的一个总数与6.1的一般水准(SSR)被检测并且2.0(SNP)每地点，分别地，到对面，所有衬里的等位基因。基于独立从SSR和SNP标记估计并且联合的基因距离，加入邻居的簇和结构一致地分析的unrooted把168个混合米饭父母分开了成二个主要的组：B线和R线，它与已知的父母家谱信息一致。从SSR和SNPgenotyping导出的基因距离矩阵高度被相关(r=0.81，P<0.001)，SSR和SNP标记两个都显示那有可区分的力量检测多型性并且为在热带混合米饭父母之中的基因差异分析是适当的。60个SSR标记的一个子集被核心亨特也基于总数与368等位基因，和簇分析选择，SSR标记的子集高度在r=通信0.91(P<0.001)，建议更少SSR标记能被用来在父母线之中分类并且评估基因差异。

简介：为了评估海洋表面风向量和海表面温度，从WindSat获得了，我们从2004年1月在时间时期上把这些数量与系在的浮标大小作比较到2013年12月。在WindSat风速度和浮标风速度之间的吝啬的偏爱为低频率风速度产品(WSPD_LF)是低的，变化from0.07到在不同选择区域的0.08m/s。全面RMS错误是为WSPD_LF的0.98m/s，从在不同选择区域的0.82～1.16m/s。在热带海洋的风速度检索结果比美国的沿海、近海的水的好。另外，WSPD_LF的风速度检索精确性比中等频率风速度产品的好。串音分析显示WindSat风速度检索从另外的地球物理的参数包含一些生气影响，例如海表面温度，水蒸汽和云液体水。在WindSat风方向和浮标风方向范围from0.46之间的吝啬的偏爱？？
