Abstract

A quantitative trait is a measurable trait that depends on the cumulative action of many genes and their interaction with the environment that can vary among individuals over a given range to produce a continuous distribution of phenotypes. The identification and mapping of QTLs for such traits has great significance for rice breeders. In this study, a genetic analysis of quantitative trait loci (QTLs) affecting 11 agronomical traits was performed using an F2 population of a cross between two Oryza sativa ssp. indica type cultivars, ‘Domsiah’ and ‘IR44’, comprising 160 plants. A total of 22 QTLs were detected for 11 traits, including two for plant height (PH), one for full grain per panicle (FG), two for flag leaf width (FLW), three for 1000-grain weight (TGW), two for number of panicles per plant (NP), three for flag leaf length (FL), two for peduncle length (Pd), one for panicle exertion (PE), two for grain yield (GY), two for basal panicle length (BPL) and two for awn length (AL).
