1, Chinese people all know the unrivaled Yuan Longping, but 95% of them have not eaten the rice he cultivated. Yuan Longping solved a most basic survival problem, Yuan Longping cultivated rice is the way to carry out hybridization, the two genetically have some differences in the rice varieties on the benign complementary.
2, while transgenic rice is a different variety of rice specific genes into a particular rice genes for breeding. Both produce genetic changes in future rice.
3, but there is less artificial intervention in hybridization, and it is still natural selection that is followed, whereas transgenic changes the gene sequence, and even genes can be interchanged between different species, which means that transgenic has a great potential risk, whereas hybrid rice is the safest.
