104S is a new thermo-sensitive genic（TG） ms material which was found from the plant group of inbreeding 99104 in Brassica napus. Investigations of fertility show that 104S has a similar changing regularity in fertility to the existing TG ms lines such as Xiangyou402S, but is different in flower morphology from the latter. The petals of 104S are bigger obviously than that of Xiangyou402S. The genetic studies indicate that the fertility of 104S is controlled jointly by a couple of recessive ms genes and a couple of mainly effective thermo-sensi...
