Sexual hybridization method for abelmoschus esculentus

Abstract

The invention provides a sexual hybridization method for abelmoschus esculentus. The sexual hybridization method comprises the following steps of: 1. selecting a flower bud on a female parent, which can bloom in the second day in the afternoon of a sunny day; 2. aslant cutting in a place far away from a base part of the flower bud by 0.4-0.6cm for 0.4-0.6cm by using a pencil knife, cutting around the flower bud by 3-4 times, cutting out a corolla to expose a style, scraping a stamen on a stamen tube from bottom to top by using a knife back, wherein anthocaulus is marked, a parchment tube is sleeved on the style, the diameter of the parchment tube is 0.7-0.9cm, the length of the parchment tube is 3.5-4.0cm, and one end of the parchment tube is closed; and 3. extending a small box for collecting pollen into a male parent flower at 7:00-10:00 in the morning of the second day, slightly tapping the base part of the flower by using index fingers to ensure that the pollen falls in the small box without picking the flower, wherein the parchment tube on the style of the female parent is taken off, the pollen is coated on the stigma by using a writing brush, and the parchment tube is sleeved after the pollination is finished. According to the sexual hybridization method, the complete stigma and the stamen tube are remained when the female parent is subjected to castration, and thus the castration success rate and the working efficiency can be improved. The parchment tube is sleeved on the style, and thus the hybridized seed purity and the legume forming rate can be increased. The flower is remained when the pollen is taken, and thus a tender legume can be harvested.

Description

Technical field [0001] The present invention relates to a method of sexual hybridization of okra. Background technique [0002] Okra is an annual herb of the Malvaceae Okra genus. It mainly feeds on tender pods. Flowers and seeds are also edible. The juice of the tender pods of okra contains pectin, polygalactose, arabinan and flavonoids, especially the content of protein and calcium is higher, and the content of mineral elements and vitamins is significantly higher than that of kidney beans. When eaten, it has a smooth taste and unique flavor. It has the functions of protecting the liver and stomach, invigorating the kidney and resisting fatigue. The tender pods are rich in trace elements such as zinc and selenium, which can enhance the human body's anti-cancer and anti-cancer ability; the rich soluble dietary fiber can take away the garbage from the human body, and the tender pods are low-energy foods, which are good nutrition and weight loss foods. Seeds can be used to squee...

AI Technical Summary

Problems solved by technology

The style with the stamen tube removed is thin and the stigma is relatively large. The parchment tube covering the style is easy to fall off. The non-maternal pollen will fall on the female stigma due to external sources such as wind and insects. The exposed style is vulnerable to external damage, reducing the purity of hybrids and the rate of hybrid pods

Use ophthalmic tweezers to strip the stamens from the stamen tube in the horizontal direction, which is slow and inefficient
