The average heterosis of spike number per plant and 1 000-grain-weight were high and obviously related to yield heterosis at 0. 01 and 0. 05 level, respectively; the average yield heterosis of F1 hybrids between common wheat and club wheat was 77. 19%(ranged from-2. 18% to 143. 42%), the average heterosis of spike number per plant and spike grain number were high and both was also obviously related to yield heterosis at 0. 01 level.

结果发现：小麦种间杂种在产量上具有明显的杂种优势，其中斯卑尔脱小麦与普通小麦所配的30个种间杂交组合产量杂种优势平均为109.24%(43.14%～187.96%)，单株穗数及千粒重平均优势较大且与产量优势的相关分别达极显著水平和显著水平；密穗小麦与普通小麦所配的30个种间杂种的杂种优势为77.19%(-2.18%～143.42%)，单株穗数和主穗粒数优势较大且与产量优势的相关均达极显著水平。

It can also be seen in smaller breeds such as the cocker spaniel and springer spaniel, as well as in mixed breed dogs.

这种病也容易出现在一些小一些的品种身上，例如可卡犬、史宾格猎犬、一些杂交的狗狗也容易得。

Codominant inheritances of these 10 SNPs were also conducted in the Tongcheng crossbred population two-generation pedigrees.

在试验杂交群体的上下代中检测了这10个SNPs的遗传方式，均呈共显性遗传方式。

The purpose of this article is to identify whether HSV and CMV play as cofactor role in the carcinogenesis.

对81例不同宫颈病变组织进行HPV16/18和HPV6/11原位杂交，同时对103例不同宫颈病变组织用DNA扩增法检测HPV、HSV 和CMV。

The highest level of expression was observed in the stem and leaf tissues and no obvious signal was detected in the root and coleoptile tissues.

通过RT-PCR和对Rht近等基因系的抑制缩减杂交，我们还克隆了14个有明显开放读码框的EST序列。

Weak equilibrium condition, orthogonality condition and energy compatibility condition are used to construct high performance elements. An ideal approach is to suppose that stress satisfy these conditions simultaneously, such as the stress mode of CH (0-1) in 2-D case.

弱平衡、正交性和能量协调条件是构造高性能杂交元的三种手段，三个条件同时满足是一种理想的应力设计方案，四边形单元CH(0-l)的应力是这种理想方案的一个代表。

Based on analyzing the problems,we propose an evolutionary algorithm by using niches technology and multi-parent-crossover technology to experiment on complex multimodal function optimization with samples.

在分析了简单遗传算法求解带约束的多峰值函数优化中存在的问题的基础上，提出了利用小生境技术和多父体杂交的演化算法，对复杂的多峰值函数优化问题进行了测试，证实该算法能够快速求出多峰函数的所有全局最优解，而且搜索效率高，达到了令人满意的效果。

Through plots experiments and 49 field comparison experiments in four seasons of two years, the impacts of different compound proportion of N, P, K and manure on the rice yield were studied.

通过2年4季的小区试验和49个大田对比试验，研究氮、磷、钾及有机肥不同用量配比对杂交水稻产量的影响。
