Cross breeding method of cyclamen

Abstract

The invention discloses a cross breeding method of a cyclamen. The cross breeding method comprises the following steps of obtaining accurate pollen collection time and pollination period through measuring the stigma receptivity and pollen viability of the cyclamen, wherein a female parent has the highest the stigma receptivity after flowering for 4 to 5 days, petals forward gather together until just unfolding, an anther and a style of the anther downwards grow, the pedals and sepals upwards grow, pollen is true yellow, and a male parent similarly has higher pollen viability when flowering for4 to 5 days; collecting the pollen of the male parent flowering for 4 to 5 days, and pollinating a stigma of the female parent flowering for 4 to 5 days, wherein a fruit matures after 5 months; picking the fruit, collecting a seed and storing. According the cross breeding method, the optimal collection period of the pollen and the optimal receptive period of the stigma are accurately judged through a flower blooming state; the optimal pollination time is determined; meanwhile, an emasculation skill is optimized; the pollination success rate is improved; pollination times are reduced; the artificial pollination efficiency of the cyclamen is greatly improved, and a foundation is laid for quickening the germplasm resource innovation and new variety breeding of the cyclamen.

Description

technical field [0001] The invention relates to the field of cross breeding, in particular to a method for cross breeding of cyclamen. Background technique [0002] Cyclamen, also known as radish crabapple, rabbit ear flower, rabbit flower, Yipinguan, bonfire flower, and petal lotus, is a perennial herb of the genus Cyclamen in the Primulaceae family. After the middle of the 20th century, it has developed rapidly in my country, and has made great progress in cultivation, breeding, reproduction, and pest control. As one of the top ten potted flowers, cyclamen has a flowering period of up to 5 months. It coincides with Christmas, New Year's Day, Spring Festival and other festivals, and the market demand is huge. At present, most cyclamen flower enterprises in my country mainly rely on imported seeds from the Netherlands, Japan and other countries for planting, and the cost is relatively high. Therefore, improving the efficiency of artificial pollination of cyclamen is of grea...

AI Technical Summary

Problems solved by technology

Cyclamen flowers have a long period from the unexpanded state (completely gathered) to the fully expanded state (the petals are gathered to roll up to fully unfolded, the anther and its style grow downward, and the petals and sepals grow upward), which is difficult to judge accurately Its pollination time requires multiple pollinations, and the efficiency is low
