Morphological approach for characterization of Indian Rice Cultivars

Rice (Oryza sativa) is one of the most important crop of the world and it is the principle food of the world’s population. It is indigenous crop in India. In this research we have taken seed of various cultivars of rice from Rajendra Agriculture University, Pusa and G. B. Pant University of Agriculture and Technology, Pant Nagar. For shake of convenience, the cultivars have catalogued and each cultivar was assigned a numerical symbol from 1 to 62. Here work mainly based on morphology of cultivars especially Growth habit and plant height to distinguished them.
