Abstract: Rice (Oryza sativa L.) is a popular cereal crop commonly used as human food. It is actually a type of grass and belongs to a family of plants Poaceae that includes other cereals such as wheat and corn. Rice is rich in nutrients and contains a number of vitamins and minerals. It is an excellent source of complex carbohydrates - the best source of energy. Rice has a renowned relationship with the humans since ages. Presently, more than half of the world’s population depends on rice as a staple food (Barah and Pandey, 2005). For developing laboratory keys for genotype identification, chemical and biochemical tests play an important role. In this study for chemical (Phenol and Modified phenol tests) and biochemical (Alpha- amylase and dehydrogenase enzyme activity) characterization, twenty rice genotypes (PR-124, IABT-17, RP-Bio-226, DRR Dhan-44, Gangavati emergency, GNV-1405, GNV-14-96-1, GNV-1415, GNV-1109, GNV-10-89, IET-23304, IET-26286, IET-24796, KRGL-20, IET-26232, SMW-09-32, IET-26290, IET-255051, MSB-43-1-2 and IET-25574) were used. These genotypes were grouped into five different colour groups viz., light brown, dark brown, black and no colour change. Rapid identification techniques are the testing procedure that utilizes specific tests to reveal chemical and biochemical differences among the seeds of different genotypes. These tests are found to be quick and accurate and used to identify varieties The chemical and biochemical tests served as a great tool in the identification of genotypes. Also developed seed keys for identification of genotypes. Also inter relationship of 100 rice genotypes between seed characters viz., length, width, length/width ratio, 1000 seed weight and seedling characters viz., germination percentage, shoot length, root length, seedling length, speed of germination, seedling dry weight were assessed by comparing the observations recorded using correlation studies.
