Abstract
Drought tolerance of indinca/javanica recombinant inbred line(RIL) at germinating stage in rice by use of 20% PEG-6000 as water-stress agent were studied.The radicle length,shoot length and the dry weight of shoot were measured after the 20% PEG treatment for 7 days.The final class of drought tolerance,derived from the sum of the drought tolerance class of each trait,was used as index in assessing the drought tolerance of RIL.The results showed that eight lines are of drought tolerance among the 270 lines,which could be used as drought tolerance resources in rice breeding and research on mechanism of drought tolerance in rice.
