Study on Flowering Habits and Sexual Hybridization of Fagopyrum tataricum
In order to explore the flowering habits of Fagopyrum tataricum and its sexual hybridization technique,Fagopyrum tataricum Pinku No.1,Fagopyrum tataricum Mi and Fagopyrum tataricum HPE7 were used as experimental materials.The flowering habits and flower apparatus structure of Fagopyrum tataricum were observed.The results showed that the number and size of flowering and pollinating flowers of Fagopyrum tataricum Pinku No.1,Fagopyrum tataricum Mi and Fagopyrum tataricum HPE7 were significantly different.In the artificial hybridization,the newly opened flowers with pink anther and smooth surface without pollination were selected to complete the emasculation.The cross combination of Fagopyrum tataricum Pinku No.1 and Fagopyrum tataricum Mi as parents showed high affinity,with the setting rate of cross or reverse cross reaching more than 36％.Fago-pyrum tataricum HPE7 was the hybrid combination of the male parent,the setting rate of the hybrid is more than 35％,Fagopyrum tataricum HPE7 was the hybrid combination of the female parent,the setting rate of the hybrid was 0,Fagopyrum tataricumHPE7 cannot be used as the maternal par-ent.
