Epistatic QTL for seed vigor identified in joint analysis of three-maturity values by QTLNetwork in 2012.

aSeeds were collected at 4, 5 and 6 weeks after heading; GP, Germination potential; GR, germination rate; GI, germination index; T50, time for 50% of germination;bChromosome on which the QTL was located;cAA represents the estimated additive effects of epistatic QTL; ** indicates significance at the level of 1%; its positive value indicates that two loci genotypes being the same as those in parent Jiucaiqing (or IR26) take the positive effects, while the two-loci recombinants take the negative effects;dAAD1, AAD2 and AAD3 represents the additive effect of epistatic QTL for the vigor of seeds collected at 4, 5 and 6 weeks after heading, respectively; its positive value indicates that two loci genotypes being the same as those in parent Jiucaiqing (or IR26) take the positive effects, while the two-loci recombinants take the negative effects;er2 (AA) represents the phenotypic variation explained by the epistatic QTL; r2 (AAD) represents the phenotypic variation explained by the epistatic QTL × development interactions.Epistatic QTL for seed vigor identified in joint analysis of three-maturity values by QTLNetwork in 2012.
