Problems solved by technology

In the search of literature from 1992 to 2012, no application technology related to branched color wheat hybrid breeding was found, and no precedents for sexual cross breeding of branched wheat Mimai No. 6 were found, which proves that the research in this area is at a blank stage

Embodiment Construction

[0034] Taking the climate environment of Dezhou (Northwest of Shandong) as an example, this hybrid breeding method is explained.

[0035] (1) Select parent

[0036] In the hybrid parent nursery, the colored wheat Mi 06-1 is selected as the female parent, and the branched wheat Mi 6 is used as the male parent, and the female parent Mi 06-1 colored wheat should choose strong plants and ears that have just pulled out the sheaths. Ears, first cut off the late-developed spikelets on the top and bottom of the female spikelets, and then cut off the wheat awns. Generally, only 8 spikelets in the middle and upper parts are left, and 4 on each side, and then the florets in the middle of the remaining spikelets are used. Take it off with tweezers, leaving only two florets with well-developed bases in each spikelet.

[0037] (2) Castration and pollination

[0038] Detassell the tidied tassels, and use the method of detasselling by picking medicines. The specific method is: use the thumb...

Abstract

The invention belongs to the technical field of crop crossbreeding and discloses a branch type colored wheat crossbreeding and propagation method. The method comprises the following steps of: (1) parent selection: selecting colored wheat ear 06-1 as a female parent and selecting branch type wheat ear 6 as a male parent and carrying out sexual crossbreeding; (2) castration and pollination: removing the anther of the female parent, pollinating when the stigma is mature after 1-4 days, 20-22 days after the pollination, stripping the young embryo for isolated culture, and carrying breeding and system selection on the young embryo; and (3) breeding and system selection: cultivating a branch type crossbreeding colored wheat new specie-ear 2008F3-number 2 on the basis of the third generation. The individual advantage of the specie is remarkably superior to the common wheat new species, the increase of each mu is above 15%, the lodging resistance and disease resistance are strong, the quality is excellent, the high yielding stability is good, the adaptability is wide and the quality is high.

Description

technical field [0001] The invention relates to a plant breeding and propagation method, in particular to a color wheat hybrid breeding and propagation method. Background technique [0002] Wheat is the second major food crop in my country after rice. At present, the selection of fine varieties of wheat is mainly carried out in China. In recent years, because the wheat breeding work in our country is in the climbing stage, no major breakthroughs have been made in the breeding of new wheat varieties. Colored wheat is a new nutritional and health-care wheat strain developed under the background of the rapid development of the agricultural science and technology revolution. Colored wheat grains have a variety of colors such as purple blue and green. Its protein and lysine content are higher than those of ordinary wheat, and it can absorb more iron, zinc, selenium, iodine, etc. from the soil, which is very important for human health. These plant-sourced nutrients are more easi...
