摘要：

Low temperature stress will lower the germination rate of rice, reduce its growth, and delay the emergence of rice seedlings from paddy water surface, resulting in decreased seedling and mortality. Here, we conducted QTL analysis for geminated rice embryo to identify QTLs with 160 RILs developed from a cross between low temperature resistant variety Tong88-7 and low temperature susceptible variety Millyang23. The germination rate and coleoptile length traits of the 160 RIL had normal distribution. Five QTLs for germination rate and two QTLs for coleoptile length were detected. The qLTG8 on chromosome 8 was detected as QTL for germination rate resistant to cold stress. In addition, the region of qLTG8 was detected as QTL (qCCL8) for coleoptile length resistant to cold stress. The qLTG12 on chromosome 12 was detected as QTL for germination rate resistant to cold stress. In addition, this region of qLTG12 was detected as QTL (qCCL12) for coleoptile length resistant to cold stress. Among QTLs resistant to cold, qLTG3, qLTG7-1, qLTG7-2, and qLTG12 were originated from resistant variety of Tong88-7 while qLTG8 was orientated from susceptible variety of Milyang23. © 2015 Korean Society of Crop Science and Springer Science+Business Media Dordrecht.
