  • a In the RI population, QTL effects were associated with the Lemont allele (the effect due to substitution of the Teqing allele by the Lemont allele). In the BC populations, QTL effects for F1 and HMP were estimated by the difference between the heterozygote and the homozygote. In the testcross populations, QTL effects for F1 and heterosis were estimated by the difference between the heterozygote (tester/Lemont) and the heterozygote (tester/Teqing). The genetic expectation of the QTL effect is the additive gene effect (a) when estimated from the RILs, the additive and dominance effects (a + d) from the F1 mean values, and the dominance effect (d) from HMP values in the BC populations.
