Under drought stress, leaf water content trait can be used as a indicator for variety evaluation. In this study, ahybrid F2 population was constructed with drought-tolerant indica rice cultivar Luhan No.1 and japonica rice cultivar Nipponbare, to analyze QTLs related with relative water content in rice. According to the results, two QTLs were detected between markers 4-27M and 4-23M and between markers 6-3M and RM276 on chromosomes 4 and 6, with the contribution rate of 4.81% -6.43% to phenotypic variation.展开更多
