Abstract: This paper deals with the ratooning power of the reciprocal crosses of Shu-fon No.1-11 with Tai-Guo-Dao-Xuan, and Ai-Nan-Zao with Tai-Guo-Dao-Xuan. It has been shown that where the Shu-fon No.1-11 is an early Sieny Variety and the Tai-Guo-Dao-Xuan is a medium one they have a stronger ratooning power; but Ai-Nan-Zao is an early sien without the ratooning power.
The following results have been obtained. First, it was found that TaiGuo-Dao-Xuan's cytoplasm had a distinct effect on enhancing the ratooning power of a single plant in those crosses of the Shu-fon No.1 with the Tai-Guo-Dao-Xuan. Second, some tendency of the interaction between the cytoplasm and the nucleus was observed. This indicated that ratooning power of their progeny would be enhanced when the base on F1(or F1')was added with the element of Tai-Guo-Dao-Xuan's nucleus; but when it was added with one of Ai-Nan-Zao's, their progeny's ratooning power would be decreased obviously; and when it was added with one of Shu-fon No.1-11s, the ratooning power of theirs didn't show any significant increase or decrease. Third, the effect of genetical genes was calculated for a try. The cross of the Shu-fon No.1-11 with Tai-Guo-Dao-Xuan showed that the addition dominance and the interaction among those additions displayed a very significant positive effect, whils the interaction between the addition and the dominance-was a very significant negative one. But in the cross of Ai-Nan-Zao with Tai-Guo-Dao-Xuan, the addition is only a very significant effect.
