How to distinguish serious fake hybrid rice seeds

According to practical experience, distinguishing true and false hybrid rice seeds must be identified in the following five aspects. Look at the stigma trails. The seeds of hybrid rice were cross-pollinated and a seed of hybrid rice was carefully observed. In the middle of the chaff inside and outside the gap, there was a little dark spot, that is, the stigma. Look at the anastomosis of the husk. Hybrid rice husks have poor anastomosis, some seeds have cracks, and non-hybrid rice seeds have good anastomosis, no cracks and tight binding. Look at the grain shape three times. Hybrid rice seeds have irregular seeds and have different sizes and thicknesses. Conventional rice seeds are neat and consistent. Look at the tip of the valley. The grain color of hybrid rice seeds is yellowish and the color of non-hybrid rice seeds is colorless. Look at the grain belly. The abdomen of the seeds of hybrid rice can be seen in a concave shape, which resembles a "V" shape. The belly of conventional rice seeds is linear.
