| Abstract: | This paper studied the fertilization of the hybrid between autotetraploid sorghum and Johnson grass and the genetic characters of the hybrid generation. The results showed that the reciprocal cross between sorghum and Johnson grass was all bred, the characters and cytogenetics of subsequent generation was stable. The heterozygous plants had great hybrid vigor. It is a prospect feed crop. |
