Drought tolerance in rice

Rice (Oryza sativa L.) is one of the staple cereal crops of the world and it is one of the main sources of carbohydrates for nearly one-half of the world's population. So, an increase in rice yield to satisfy human needs is a pressing requirement. Agronomic characters such as high plant, length of panicle, length of flag leaf, number of seed per panicle, the weight of thousand rice, length and width of rice and tolerance to salt are the deciding factor for yield in rice.

In a pot experiment was conducted to evaluate the physiological characteristics and root characteristics associated with drought tolerance of rice varieties including indica rice subspecies, japonica rice subspecies, hybrid male sterility line and temperature sensitivity of wild rice species for comparison with drought-tolerant Indica rice varieties. At the effective tillering, the pot experiment was to drain the water and then dried for 4 days, then watered again.
