Abstract

The restricted genetic basis of the major rice varieties has resulted in a decrease in physical variation among them, necessitating the creation of efficient and reliable varietal identification tests, especially for the individuals who oversee and certify the quality of seeds. Ten rice varieties were tested for eleven different chemical tests such as phenol test, modified Phenol test, NaOH test, FeSO4 test, KOH test, gelatinization temperature test, aroma test, GA3 test, 2,4-D test, kinetin test, potassium iodide test. Based on how different genotypes' colour reactions affected the seed's ability to discriminate between the ten paddy varieties. Each of the eleven chemical tests separated the seed variety into two to six classes based on their responses. Even though no one test was able to characterize any specific variety, the eleven chemical tests together were able to distinguish each of the ten different varieties of rice. Thus, these chemical tests were straight forward, fast, and consistent and it might be used to distinguish between several rice cultivars.

Conclusion

The findings concluded that individual chemical tests have limited utility and these tests may distinguish any number of varieties when performed in a complimentary sequence or in combination. In order to identify the rice crop varieties, these straightforward, quick, and reliable tests are of great utility. The study also showed that, these tests might be used to accurately determine the purity of the rice variety for regular testing.
