Abstract: A set of 9 ×9 full diallel (GriffingⅠ) crosses were made using nine different inbred lines of maize?(Zea mays L. ). Genetic Effect of starch RVA viscosity properties was studied. The results showed over-MP heterosis was detected in Breakdown (BD) and Setback(SB),respectively,and over-LP heterosis in other properties. Correlation coefficients of Peak Viscosity(PV),Trough Viscosity (TV),Final Viscosity (FV) and SB in hybrids between the male parent were greater than those with the female parent. Broad sense heritability (H2B) of other properties was relatively high except Peaktime(PT) and Pasting Temperature (PTP). The narrow sense heritability (H2N)?of PV,TV and FV was also very high. Additive effect was the main factor of genetic variance for TV and FV. Dominance effect was the main factor of genetic variance for BD. Both additive and dominance effects were almost equally?important factors of genetic variance for other starch RVA viscosity properties.
