Parental propagation method of kale with hard-to-loose anthers

Abstract

The invention discloses a parent seed reproduction method for anther kale with pollen difficult to scatter. The method includes the following steps that (1) a hole tray is selected to conduct sowing and seeding cultivation at the end of summer and in the beginning of autumn; (2) transplanting and planting are conducted, and when the kale seedling grows four leaves and one center, the kale is planted in the field; (3) old leaves are removed; (4) parent breeding is conducted, wherein when the kale produces shoots, blooms and begins to conduct bud pollination, the flower bud going to bloom of a plant B special for pollen collection is cut off by 31% to 35%, the stigma of a plant A is peeled and exposed out through a nipper the next day, the day before collection, the pollen of the plant B is smeared on the peeled stigma of the plant A, and the cycle is repeated till the parent pollination is finished. The parent seed reproduction method for the anther kale with the pollen difficult to scatter is simple and easy to operate, saved labor is more than doubled, the pollen quality is high and the fructification percentage is more than doubled. According to the parent seed reproduction method for the anther kale with the pollen difficult to scatter, during bud pollination, people do not need to go around to search for the pollen or to scrape the anther with the nipper to take the pollen, and thus pollen collection is easy and convenient and time is saved in seed reproduction.

Description

technical field [0001] The invention relates to a plant breeding method, in particular to a method for parental breeding of self-incompatible kale which does not loose anther powder, and belongs to the technical field of plant cultivation. Background technique [0002] Kale, also known as flower cabbage, leaf peony, and colorful cabbage, is a biennial herbaceous flower of the genus Brassica oleracea. Native to the Mediterranean coast, it is planted more in Britain, Holland, Germany, Japan and the United States, and is widely cultivated all over the world. my country began to introduce and cultivate it in the 1990s. It is more common in Jiangnan regions such as Shanghai and Hangzhou. It is gradually introduced in North China and Northwest China, and the Northeast region is still in the stage of introduction experiments. [0003] As a herbaceous flower, the leaf shape of kale is beautiful and changeable, and the heart leaves are rich and colorful. The ornamental period can be...

Problems solved by technology

[0004] The parental reproduction of kale mostly uses pollination at the bud stage, and some of the parental materials have anthers that do not disperse or are difficult to disperse, which makes it difficult to find pollen on the stripped stigma, and it is difficult for the parents to reproduce

When pollinating at the bud stage, because the anthers of the parent’s normal flowering are extremely difficult to loose pollen, it is necessary to look for flowers with loose anthers in the plant, which takes a lot of time and is often difficult to find

When the powder is not loose, use tweezers to scrape the non-loose powder anther, and then apply the pollen on the stripped stigma, because the scraped pollen has high humidity and low seed setting rate
