| Abstract: | Aimed at identifying PHS tolerant breeding materials and assessing the efficiency of the corresponding markers in selecting genotypes with higher PHS tolerance, four PHS tolerance associated markers ( Vp1B3, Xgwm155, Xwmc468 and Xgwm397) were employed to screen 67 Chinese spring red grain cultivars (lines). The results showed that of the 67 cultivars tested, the germination index of 12 cultivars were lower than 1%, that of 42 cultivars were between 1% and 5%, and 13 cultivars were over 5%. The relationships between the PCR products variation of the four markers and the germination index of the tested materials were analyzed and indicated that the variation of STMS marker Xwmc468 was associated with PHS response, but that of STS marker Vp1B3, STMS marker Xgwm397 and SSR marker Xgwm155 were not. Among the 12 cultivars with germination index lower than 1%, 8 cultivars had PHS tolerance after being identified by Xwmc468. |
