Objective:
To find the sexual reproduction characteristics and improve the seed propagation and new variety breeding of Fritillaria cirrhosa.
Method:
Flower, anther and pistil development were observed. Pollinating in different development period and bagging were used to measure stigma maturity situation and natural outcrossing rate.
Results And Conclusion:
It took 12 days from floral bud emergency to finished flowering. It was observed that anther opened in longitudinal direction and pollen was ejected for 2-4 days continuously. Pistil matured earlier, and chapiter could be fertilized from middle bud stage the third day after flowering, but the most suitable time was 2-3 day after the corolla opening. The natural outcrossing rate was 81.9%. F. cirrhosa is a typical xenial plant.

Trihybrid Crosses
Some of Mendel’s crosses examined three pairs of contrasting characteristics. Such a cross is called a trihybrid cross. A trihybrid cross is a combination of three individual monohybrid crosses. For example, plant height (tall vs. short), seed shape (round vs. wrinkled), and seed color (yellow vs. green).
The F1 generation plants of a trihybrid cross are heterozygous for all three traits and produce eight gametes. Upon self-fertilization, these gametes have an equal chance to...
