Embodiment Construction

[0029] The present invention will be further explained below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and not to limit the protection scope of the present invention. In practical applications, improvements and adjustments made by those skilled in the art according to the present invention still fall within the protection scope of the present invention.

[0030] 1. Basic conditions of the test site

[0031] 360m 2 The onion seed production net shed is located in the seed production farm of Shanghai Huihe Seed Industry Co., Ltd. The protective net is a 60 mesh nylon insect net. The parent-to-parent ratio is 1:4.3; the parent-to-parent row spacing is 35cm, and the plant spacing is 30cm. Cut off the male plants after the onion blooms.

[0032] 2. Test onion varieties

[0033] The test onion varieties in this experiment are red onion HO1503 and yellow onion HO1517, as shown in Table 1. Th...

Abstract

The invention discloses a method for producing Allium cepa L. seeds through flies, and belongs to the technical field of Allium cepa L. hybrid pollination for seed production. The method comprises the following specific steps: induced breeding and larva cultivation of the flies, Allium cepa L. pollination, harmless treatment and the like. Through test exploration on a series of conditions such as the induced breeding time, the induced breeding method and the larva cultivation of the flies (mainly Calliphorna Vicina Robineall), the pollinating density, the harmless treatment and the like, a pollinating method which is low in capital investment, simple and easy in operation and high in pollinating efficiency and is suitable for large-area Allium cepa L. hybrid seed production is obtained.

Description

Technical field [0001] The invention belongs to the technical field of onion hybrid pollination seed production, and particularly relates to a method for onion seed production using flies. Background technique [0002] Onion (Allium cepa L.) is a biennial vegetable of the genus Allium of the Liliaceae family. It has a wide cultivation area in my country and is one of the important export vegetables in China. Onions are hermaphroditic and entomophilous cross-pollinated crops. The male and female flowers are very small, with about hundreds of small flowers per inflorescence. At present, most of the seeds used for onion production are hybrid F1 generation. Large-scale use of artificial pollination methods for seed production is difficult, low in efficiency, and costly, and has no practical production significance. Insect-assisted pollination has become the first choice. Bee-assisted pollination has been widely used in cross-pollinated plants, while the use of fly pollination in man...
