A RIL population was used in this study, which was derived from a cross between a temperate maize germplasm inbred line B31-1 and a tropical maize germplasm inbred lines Huangzao 4. A genetic linkage map was constructed comprising of 153 polymorphic markers. Among the 153 polymorphic markers, 82 markers showed the significantly segregation distortion（P〈0.05）, favoring either the marker alleles of female parent 1331-1（62.50%） or male parent Huangzao 4（37.50%）. Segregation distortion marker distribution along the present molecular maps of maize was far from uniform, with clusters of tightly linked loci and single marker. Nine segregation distortion regions were detected on 10 chromosomes, indicating that possible causes for segregation deviation of molecular markers are genetic selection.

以8个玉米自交系为供试材料,采用2因素裂区设计,在玉米苗期到成熟期遮阴(遮光率为90%),研究玉米自交系的耐阴性及其在遮光胁迫条件下的植株性状的变化。结果表明:参试材料耐阴湿的程度从高到低为:06CIn967-11>06CIn892-2>06CIn967-4>06CIn892-11>06CIn891-4>06CIn891-15>06C984-2>06C984-8,其中,同一来源的自交系耐阴性差异不显著,不同来源的自交系耐阴性有一定差异;在弱光下,玉米材料的雄穗分化、植株和叶片的生长受到了极显著抑制,不同基因型材料的植株性状对遮光的反应也不同;遮光对不同性状的影响不同,对雄穗分化的影响最大。因此可以根据不同材料性状的变化来筛选耐阴材料。

目前,多模态神经影像数据被广泛应用于阿尔茨海默症(AD)分类研究,然而,这些研究方法存在着一定缺陷。首先,原始特征维度较高且包含大量冗余信息,需要大量的计算资源进行处理和分析。其次,同一患者的完整多模态数据不易获得,导致样本数量较少,不利于训练出可靠的分类模型。为此,提出了一种基于最大相关-最小冗余和典型相关性分析的AD分类方法(mRMR-CCA)。首先使用最大相关-最小冗余(mRMR)算法从各模态数据选择出与分类标签最相关的判别性特征,然后使用典型相关性分析(CCA)算法来挖掘多模态数据间的内在联系,最后进行分类。使用阿尔茨海默氏病神经影像学倡议数据库中的数据进行了实验,实验结果证明了此方法在AD分类中的有效性。
