Chromosome 1
Comments The seed dormancy QTL sd1.1 is a major loci and explains 22.0% phenotypic variance in the F2 population derived from cultivated Oryza sativa and the annual wild species O. nivara. The O. nivara allele produces an O.nivara like phenotype of seed dormancy and where the gene action is additive. O. nivara seeds exhibit stronger seed dormancy and delay in germination than O.sativa. Seed dormancy in O. nivara is effected by the embryo, as shown by its retention when the pericarp is removed.
