Rice Cultivation and Yield Improvement

Rice is the predominant crop of Tamil Nadu state, India that occupies about 30% of the total cropped area. However, grain type and quality are the critical traits that determine the market value and domestic consumption rice variety. Most of the households of Tamil Nadu, India prefer to consume medium slender to fine grain type of rice. Hence, the present study was conducted to induce medium slender grain type in popular rice variety ADT 37 (Aduthurai 37), a short bold rice variety using gamma rays (GR) and electron beam (EB) mutagens.
