What are the disadvantages of traditional rice?

What's the difference between hybrid rice and common rice? There is a great difference between hybrid rice and common rice, which is a reasonable topic discussion and a brand-new upgrading development trend of modern agricultural development. Give you a spectrum of the difference between hybrid rice and ordinary rice, and friends can figure out the difference. Friends can refer to the content:

First, the difference between hybrid rice and common rice depends on the difference after artificial intervention:

Since the 1950s, people's professional knowledge about artificial intervention in the development of green plants has become more and more perfect. At that time, people realized that genetic changes could make green plants adapt to the new environment, and at the same time, green plants could bear a lot of fruits. Therefore, hybrid rice gradually appeared and was gradually accepted by all regions of the world. Generally, rice is a natural substance. According to the discovery of archaeologists, rice first appeared in China, with a history of more than 7,000 years. Archaeologists discovered the first rice. Biologists have found that most of the ancient ordinary rice is not much different from today's ordinary rice. It is only through careful artificial planting that the grain size of today's ordinary rice is higher, but it must be emphasized that the difference is very small. Hybrid rice is completely different from ordinary rice, because people interfere with rice inheritance, so the yield of hybrid rice completely exceeds that of ordinary rice.

Second, there are great differences in breeding level between hybrid rice and common rice:

Hybrid rice and common rice are very different in breeding level. Hybrid rice is the seed produced by the fusion of different rice, which means that hybrid rice must have a male parent and a female parent to produce seeds. This is also the advantage of hybrid rice, which is mainly manifested in the increase of yield and manufacturing. Hybrid rice has excellent disease resistance, which ordinary rice seeds do not have.

Third, hybrid rice only has artificially shaped seeds, and generally rice will have seeds:

The seeds of hybrid rice must be produced manually, and it is not easy to keep the seeds by yourself. However, generally speaking, rice can keep its seeds, and at the same time, it must continue to live and reproduce.
