通过改进的遗传策略来优化染色体长度，实现对聚类个数进行全局寻优，利用FCM算法加快聚类中心参数的收敛；并引入免疫系统的记忆功能和疫苗接种机理，使算法能快速稳定地收敛到最优解。

To evaluate the salt tolerance, the salt tolerance of 93 accessions of wild emmer from Israel was studied prilimarily with water culture method .

野生二粒小麦与普通小麦的A、B染色体组在聚类图中可以大致被分为两类，二者之间的遗传相似系数不高。

The results of the heterozygosity were consistent with that of PIC.

对D遗传距离的计算表明：用UPGMA法进行聚类分析，结果8个鸡品种被聚为3类。

Followed by the decomposition phase is optimal feature subset selection, in which the optimal feature subset acquired the best divergence is obtained according to interclass/intraclass distance of the training samples. This procedure is implemented by a Genetic Algorithm, with each possible feature subset encoded as chromosome. Fitness scores in GA are calculated and evaluated based on Jeffries-Matusita distance of the selected training samples.

然后，对这些线性光谱特征利用遗传算法结合训练样本计算类内/类间距离搜索最优分类子集，其具体染色体编码取可能的特征号，适应度函数基于样本平均Jeffries-Matusita距离计算。

The experimental results were as follows:(1)The genetic relationship dendrogram was made and the relative genetic distance was calculated by cluster analysis with the amplifi...
