To obtain basic information on the breeding of long ear length and multiple branch rapeseed varieties, the seven varieties, Isuzu, Miyuki, Norin 25, Rang, Yongdang, Cresus and Tower were used in diallel crosses in 1979. Ear length, first branch and second branch per plant for the parents, F1's and F2's of the 7 x 7 partial diallel crosses were measured in 1981 for analysis of their genetic behavior and the results obtained indicated that the ear length of F1's showed complete dominance for long ear length, and both additive and dominance genetic variance for long ear length, and both additive and dominance genetic variances were significant
