Evaluation of morphophysiological traits associated with drought tolerance in rice

Sixteen local rice germplasm lines of close phenology were studied for selected root and shoot traits. These traits were evaluated for yield stability under reproductive stage drought in rice. It was observed that well-developed root system as measured in terms of root pulling resistance helps in maintaining higher plant water status and yield stability. Delay in flowering seems to be due to low plant water status and was linked with drought susceptibility.
