Abstract

Unconditional QTL mapping and conditional QTL mapping were conducted for growth duration (GD), plant height (PH) and produtive panicle number per plant (PN) using a recombinant inbred line (RIL) population derived from a cross between japonica rice Xiushui 79 and C Bao. The 254line RIL population was planted in two environments, Nanjing and Sihong, Jiangsu Proivince. Results showed that with predominant additive effects in all QTLs for GD, PH and PN detected by the two methods, the epistatic effects explained a small percent of phenotypic variation. No interaction was detected between additive QTL and environment, or between epistatic QTL pairs and environment. After growth duration was adjusted to an identical level, RM80160bp was detected as an applicable elite allele for PN, with an additive effect of 0.71. After produtive panicle number per plant was adjusted to an identical level, RM448240bp was detected as an applicable elite allele for GD, with an additive effect of 464. After plant height was adjusted to an identical level, RM80160bp was detected as an applicable elite allele for PN, with an additive effect of 0.62, and RM448240bp was detected as an applicable elite allele for GD, with an additive effect of 3.89. These applicable elite alleles could be used to improve target traits without influencing the other two traits.

Key words： japonica rice; growth duration; plant height; productive panicle number per plant; unconditional QTL mapping; conditional QTL mapping; recombinant inbred line
