Abstract:A set of diallel crosses involving 8 parents was made to study the genetic models for main characters in wheat.The results showed that the grain weight and ear number per plant accorded with the additive models;that 1000-kernel weight,grain numbers per spike,set spikelets per spike and ear length accorded with the additive-dominant models;and that plant height and neck length accorded with the additive-dominant-epistatic models.The number of dominant genes which control most agronomic characters differed greatly among the parents,in which P 5 and P 3 possess the greatest number of dominant genes.The number of dominant genes controlling different characters differed among parents.
Keywords:wheat  quantitative character  diallel crosses  genetic model
