根本提高动物生产率的方法问题有着科学上和生产上的特殊意义.科学和实践,给予在实验遗传学的研究中所探讨出的、能够控制杂种力(杂种优势)的新方法以充分的证明,我们已经获得显著提高许多农业动物生产率的强有力的方法.新方法表现在创造和生产上利用杂种玉米的时候,表现在许多新的农作物 The problem of fundamental ways to raise animal productivity is of scientific and production-specific significance.Science and practice provide new ways of controlling the hybrid power (heterosis) that we have explored in experimental genetics to adequately demonstrate, We have already come up with powerful ways to significantly increase the productivity of many agricultural animals.The new approach is manifested in the creation and production of hybrid maize that is manifested in many new crops
