crossover value

Crossover value of the linkage was about 40.90.

抗瘟性与光敏不育性是连锁遗传的，交换值接近40.90。

By adjusting mutation value and crossover value, novel genetic algorithm formed a positive feedback to accelerate searching speed and convergence speed.

其中遗传算法创新在于通过自我调节变异和交叉因子的值，形成正反馈机制，加速对解空间的搜索速度和收敛速度。

The algorithm is based on the adaptive mutation operator and crossover operator that adjusts the crossover rate and frequency of mutation of each individual, and adopts the gradient of the individual to decide their mutation value.

该算法基于自适应交叉概率算子和变异算子，根据进化代数和群体的适应值，动态调整各个个体的交叉概率和变异概率，并在变异量的确定上引入了梯度的概念。

Crossover value is 4. 63%-10. 81%.

交换率为4.63%～10.81%。

Both Nan-Geng 15 and Zhong-Bai 4 have two linked dominant genes with crossover value 30% operating in the 3 strains at booting stage.

南粳15和中百4号均由两对连锁的显性基因控制，交换值为30%。
