人类作物育种的历史就是一部人类不断追求技术速度与精度的历史。在8000年前农业产生初始,人类仅仅依靠植物的自然变异来选择产量、品质表现优良的品种来种植。但作物的自然变异效率太低,于是上世纪30年代杂交育种技术的推广,大大加速了人类利用自然变异的速度。而上世纪70年代基因重组技术的发明,提醒人们可用其加快作物基因变异的速度, The history of human crop breeding is a history of human constant pursuit of technological speed and precision. In the beginning of agriculture 8,000 years ago, humans relied solely on the natural variation of plants to select varieties with good yields and good quality for planting. However, the natural mutation efficiency of crops is too low. Therefore, the popularization of hybrid breeding technology in the 1930s has greatly accelerated the rate of human use of natural variation. The 70s of last century, the invention of gene recombination technology, to remind people that it can speed up crop genetic variation,
