【Abstract】 Formula for estimating specific combining ability variance of each parent (σsi2) for diallel cross method 4 was given by Griffing in 1956.But for the other three methods,there has been no literature that specially discussed the question.In this paper,formulae used to estimate σsi2 were presented for each of the three methods.The results are as follows:Method 1:Method 2:Method 3:更多还原
