A linkage map was constructed using 151 polymorphismic markers.The map spans1841.9 cM covering 12 rice chromosomes with an average interval of 12.1 cM,which wellintegrated the markers from the high density linkage maps of rice.

以151个多型性标记位点构建了12条染色体的遗传连锁图谱，该图谱以标记间平均间距为12.1cM覆盖了水稻基因组的1841.9cM，该图谱较好地整合了目前已发表的水稻遗传图谱上的分子标记。

These are like protective coverings on the ends of chromosomes.

它们就像是染色体末端的保护膜。

On the base of Simple Genetic Algorithms, ranking every generation's fitness, and add the function which can control the cross rate and mutation rate. This way not only can overcome the SGA's slowly speed of constringing and bad stability, but also can improve the effect of optimizing function.

该方法在简单遗传算法的基础上，将每一代染色体的适应度排序，并添加了交叉率和变异率的自适应控制函数，既克服了简单遗传算法收敛速度慢，稳定性差的缺点，又改善了函数优化效果。

According to the difference of homologous chromosomed, we can easily judge it is a cross-pollination plants.

依照不同的同源染色体我们能够很容易的判定这是一种异花授粉植物。

内容介绍了长穗偃麦草的特性和染色体组型，克服杂交不育和杂种不育的方法，杂交育种的程序及其遗传分析和选出的小偃麦八倍体种、异附加系、异代换系与丰产抗病的小偃麦新品种。

In order to correct the locality and partiality in the classical analysis method for investment, a genetic algorithm used in short-term stock investment analysis is proposed. Significance of chromosome, adapt value parameter in the stock market is explained and an applied scheme of selection, crossbreed, and variation operator is designed.

针对传统投资分析方法的局限性和一定程度的片面性，提出将遗传算法运用于股票短期投资分析，具体解释了染色体、适应值等参数在股市分析中的实际意义，并设计了选择、杂交、变异算子的使用方案，同时改进了算法——提出"伸展算子"。
