Artificial emasculation hybrid seed production method for okra

Abstract

The invention discloses an artificial emasculation hybrid seed production method for okra. The hybrid seed production method comprises the steps of: selecting a seed production base, preparing sowing, sowing seeds, performing field configuration of male parents and female parents, preparing before hybrid seed production, performing artificial emasculation, performing fertilization, performing preservation of a pure state after finishing the fertilization, performing gathering, processing and storage, and performing field management. The hybrid seed production method is characterized in that the male parents and the female parents are configured in the ratio of the male parents and the female parents being 1:6-8, and the male parents are planted at one ends of the female parent region; before seed production, pulling up abnormal plants, bad plants, variants and diseased plants in seed production fields; the day before the seed production, removing all the flowering flowers and immature pods from female parent plants; on that morning of removing flowers and emasculation, removing all the newly flowering flowers the same day; using buds which are not opened and are white and fresh on the female parent plants as emasculation targets, after 4:00 p.m. each day, removing the flowers and performing emasculation, and removing corollas together with stamen pipes so as to enable pistils to be exposed; and after fertilization, timely removing selfing pods from the female parents, and flower pods of which the tops are not cross-fertilized, wherein the field management comprises the steps of: watering for 0-1 time, and performing disinsection for one time. The method maintains the purity and the superior specificity of hybrids.

Description

technical field [0001] The invention relates to an artificial emasculation hybrid seed production method of okra, which belongs to the field of agricultural technology. Background technique [0002] Okra (Abelmoschus esculentus Linn.) is an annual herbaceous plant belonging to the Malvaceae okra family. It is native to tropical Africa and is a short-day crop. Tropical and subtropical regions. The whole body of okra is a treasure, and it is also a crop for medicinal cauliflower and feed. Li Shizhen recorded in "Compendium of Materia Medica": Okra is sweet, cold, and slippery in nature and taste, enters the heart, lung, kidney, stomach, liver, and bladder meridian, and can treat diseases such as spleen deficiency, fatigue, intestinal dryness, constipation, malignant sores, and furuncles. Okra roots, stems, flowers, seeds, etc. can be used as medicine. Its roots can benefit water and reduce swelling, treat gonorrhea and milk obstruction; The seeds invigorate the spleen and i...
