At present, there are many varieties of seed markets. Farmers always encounter “happy troubles” when purchasing good breeds. However, because they have indecisive ideas, they are often taken advantage of by speculators. Because farmers' friends themselves lack a certain amount of scientific ability to identify themselves, they are often deceived. The following points are valid methods for identifying the authenticity of hybrid rice seeds for reference.

A look at the seeds "three certificates"

All seeds with seed business licenses, quality certificates, and pest and disease phytosanitary certificates for plant protection departments are high quality hybrid rice seeds. Otherwise it is a fake hybrid rice seed.

Second, look at the uniformity

Hybrid rice seeds mixed with other rice have irregular grain shapes. The mixed male parent or other japonica rice was significantly slimmer and fuller than the hybrid rice seed, while the japonica rice was more rounded.

Three to see the color of the chaff

The seeds of the hybrid rice seedlings have slightly uneven tan and other physiological variegated colors, while the paternal and maintainer grain colors are relatively uniform. Maintainer lines and other hybrid grains have higher transparency than hybrid rice seeds, and the hull ratio hybrid rice The seeds are smooth.

Four to see the seed purity

Hand-scroached on the seeds, there are solid particles such as soil particles, sand grains, and other impurities on the palm of the fingers, and the fingers are stained with fine powder, which proves that the seed purity does not meet the national standard (99%).

Five to see the seed moisture content

A simple method is to bite the grain with a tooth. If there is a sharp noise, the moisture content is basically normal. If there is no crackling or the grain is irregular, the moisture content of the seed is generally higher than the normal standard (11.5%).

Six to see the stigma track

The grains of non-hybrid rice are mostly self-pollinated, the stigma of the pistil is not exposed, and the stigma remains in the interior of the chaff. The peeling of the chaff reveals a light black stigma on the top of the rice. The hybrids were cross-pollinated and the stigma was exposed. After careful observation of the gaps between the inside and outside of the grains, a small black spot, namely the stigma, was found. This is an important basis for identifying hybrid rice seeds and other rice grains.

Seven to see the determination of staining

The method is to cut the rice husks longitudinally into two halves from the embryonic part, wash each half into the red ink diluted 60 times, immerse it in the red ink, and remove it with clean water after 1 hour, if the embryos are not stained or stained. Shallow, proves seed vigor; if the stain is deeper, it proves that the seed has lost its vitality. In this way, the non-germinated spoilage seeds in the hybrid seed can be identified.
