Abstract

QTLs with epistatic effects and environmental interaction effects for the developmental behavior of plant height in rice were studied by conventionaland conditional methods for quantitative trait loci (QTLs) by mapping witha doubled-haploid population of 123 lines from IR64/Azucena in three environments. The results showed that epistatic effects were important and most epistasis could be detected only by conditional QTL mapping, while most non-epistatic QTLs could be detected by both conventional and conditional methods. Many modificative QTLs showed only epistatic effects without their ownadditive effects at some stages. QTLxenvironment (QE) interaction effects were detected more often than QTL main effects for plant-height behavior, which might indicate that gene expression could be greatly affected by the environment. No QTLs had effects during the whole of ontogeny. Conditional QTL mapping might be a valid way to reveal dynamic gene expression for the development of quantitative traits, especially for epistatic effects.
