AB  - Genetic parameters of some characters in rice evaluated with the use of two mating design: diallel
and NCIII. Analysis of variance showed significant differences among genotypes for all studied traits in diallel
and north NCIII mating design. The results of genetic parameter estimations for diallel mating design revealed
the existence of additive-dominance effects in controlling studied traits. Relatively high broad sense heritability
observed in Kernel Length (KL) and Final Viscosity (FV) trough diallel mating. The results of genetic
parameter estimations for NCIII mating design showed the presence of additive-dominance effects in
controlling of all studied traits. This results also indicated that the character&#146;s day to 50% of flowering (DTF)
and FV controlled by over-dominance of gene effect. Broad-sense heritability was high for all traits and it had
highest amount in KL through NCIII. The results of genetic parameters estimation of NCIII mating design
approved results of diallel crossing method for FV in the existence of additive-dominance gene effects. Also,
for DTF, the results of genetic parameters estimation through NCIII mating design confirmed results of diallel
mating design. But it didn&#146;t apply for KL. Due to the lack of consistent conform of estimates for some traits,
full following to the results of diallel designs will not lead to selecting good traits and effective breeding
methods. Thus, according to the results of this study it suggested that the decision to select a breeding method
for desirable traits based on the type of gene actions, made by using biparental progeny designs.
