Method of artificial hybridizing ang pollinating lotus exempting from male

Abstract

The invention provides a castration-free artificial hybridization lotus pollinating method, and its character: the artificial hybridization pollinating method is as follows: 1, selecting excellent-character male and female parents of lotus; 2, in 1-2 days before the hybrid parents come into flower, using bags to cover and isolate the buds; 3, as the female parent comes into flower on the first day, gathering the flowers of the meal parent coming into flower on the second day, temporarily taking down the bags of the flowers of the female parent, picking 6-8 stamens of the flowers of the male parent to put in honey solution in the stigma discs of the flowers of the female parent, slightly stirring to diffuse the pollens into the honey solution, then covering back the isolating bags, and completing the pollinating procedures; 4, as the female parent comes into flower on the second or third day, eliminating the bags to make the flowers open in natural state, successively putting them in the water to grow so as to complete the hybridization, waiting for the fruits to be ripe to gather the seeds. It eliminates the procedure of castrating, simple to operate, unable to damage the flowers, saving time and labor, and high-success rate of breeding.

Description

technical field [0001] The invention belongs to plant hybrid breeding technology, in particular to a water lily method for male-free artificial cross-pollination. Background technique [0002] In the existing water lily cross-breeding process, in order to ensure pure hybridization, the flowers of the female parent must be artificially detasseled to prevent self-breeding. The artificial hybridization of water lilies still uses the traditional artificial detasseling method at present, that is, the sepals and petals are manually peeled off, and the stamens are pulled out with tweezers a few days before the female parent blooms. Moreover, in order to prevent contamination of the stigma during this operation, the operator's hands must be wiped and disinfected with alcohol, and all utensils must be sterilized at high temperature. The water lily grows in the water, and the operator has to stand in the water and bend down to operate when completing the detasseling process, which ta...

AI Technical Summary

Problems solved by technology

Water lilies grow in water, and the operator has to stand in the water and bend over to operate during the detasseling process, which is laborious and inefficient

In addition, because the water lily has many petals, and the petals are tightly interlocked, when the petals are peeled off and the stamens are removed, the natural structure of the flower will inevitably be damaged, and the internal physiological and biochemical processes will be affected, and the fertilization process and subsequent development will be changed. The developmental conditions of fertilized eggs, the effect and success rate of hybridization are very low

In 1927, the famous British plant breeder Amos Perry pollinated 159 hybrid combinations, but only one combination got fruit, and the success rate was only 0.63%.
