Comments The potted plant experiments carried out in green house at Hangzhou, China. The two seedlings of every line were potted with 15 kg of air-dried soil per pot and every line was planted in three pots. The temperature in the greenhouse ranged from 22C to 39C. The experiments were maintained under flooded conditions during the growing period. Panicle number was recorded after harvest. Fertility and cultivation practices were consistent with optimum rice production for these regions. One-way ANOVA (SAS/6.11, GLM) and interval-mapping analysis (Mapmaker/QTL) were performed for detecting molecular markers and QTLs. Epistasis for variations in the parameters was analyzed using the program QTLmapper. P < 0.005 for the Type-I error and a log-10 likelihood ratio (LOD) value of 2.4 were used as criteria to indicate putative QTL positions. The effects of a single allele substitution (assuming additivity between alleles) and R2 values for each of the putative QTLs were estimated. Correlation analysis between the measurement parameters was performed using the correlation procedure of SAS. It is an epistatic loci for panicle number QTL (feature accession ID: CQJ4) on chr-2. It contributes about 12% of total variation.
