The allotriploid interspecies(BCC) were obtained by reciprocal crosses between Brassica carinata(2n=4x=BBCC=34) and Chinese kale(2n=2x=CC=18).The interspecies displayed a stronger growth than that of parents and intermediated to the leaf color of their parents.The plant type,flower shape,and flower color tended to parent B.Carinata and the white flower color was the same as that of Chinese kale.Meiosis observation of the allotriploid showed that 9 bivalents and 8 univalents(9Ⅱ+8Ⅰ) were formed at diakinesis ...
