Problems solved by technology

During the search from 1992 to 2010, there was no report on the application of branched wheat to production in these 18 years of literature, let alone the sexual hybridization of branched wheat Mimai 4 (former code 2000-2F4-5) The precedents that have been cultivated prove that the research in this area is in the blank stage

Embodiment 1

[0037] Select parents: Among the hybrid parents, choose Jinan No. 17, the original code name 924142, as the female parent, and the branched wheat as the male parent (branched wheat), and choose the ears that are strong and have just drawn out the leaf sheaths. Generally, the main ear is better. , first cut off the late-developed spikelets on the upper and lower sides of the female spikelets, and then cut off the wheat awns. Generally, only about 10 spikelets in the middle and upper parts are left, and 5 spikelets on each side, and 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.

[0038] Detasselling: emasculate the tidied tassels, and use the method of detasselling by picking herbs. The specific method: use the thumb and middle finger of the left hand to clamp the entire wheat ear, gently press the inner and outer glumes of the flowers one by one with the index finger,...

Embodiment 2

[0054] This variety is suitable for planting in cinnamon soil, brown soil, sandy black soil, sandy loam soil, Jinan No. 17 (former code 924142) and similar ecological planting areas, with an average yield of more than 300 kg per mu. The sowing date is September 25 -Sow on October 5th or when the average temperature is 18-16 degrees, the sowing row spacing is 16-18 cm, the sowing is 5-6 kg per mu, and the sowing amount is reduced or increased according to the time of sowing. Before sowing, organic fertilizer, nitrogen, phosphorus, potassium and micro-fertilizer should be applied together. Water the overwintering water according to the water content of the soil before the year, and topdress with urea in spring combined with watering back to the green water, strengthen hoeing during the greening period, manage according to the growth of wheat after jointing, and prevent and control diseases and insect pests in the middle and late stages.

Abstract

The invention relates to a hybrid wheat breeding method. The hybrid wheat breeding method comprises the following steps of parent selection and emasculation, generation-adding breeding and systematic selection. Through the hybrid wheat breeding method, novel hybrid wheat is obtained. The hybrid wheat breeding method has the advantages of simple processes, strong operability and high rate of emergence. A yield per mu of the novel hybrid wheat obtained by the hybrid wheat breeding method is improved by about 15%. The hybrid wheat obtained by the hybrid wheat breeding method has strong lodging resistance and disease resistance, good quality and a stable and high yield. A planting cost of the hybrid wheat obtained by the hybrid wheat breeding method is reduced in the case that a seed utilization amount per mu is saved by above 30%.

Description

technical field [0001] The invention relates to a method for propagating plant seedlings, in particular to a method for breeding and propagating hybrid wheat. 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. Over the years, due to the climbing stage of wheat breeding in our country, no major breakthroughs have been made in the new wheat varieties bred. Wheat seeds are the most basic and important means of production in agricultural production. Farmers are most concerned and worried about seeds, because wheat Seeds are related to their farming benefits, so any wheat seeds in agriculture will have the quality and benefits. "A single seed can change the benefit of farmers in a region or a province". The use of hybrid vigor is a common approach for the development of species crop breeding. The use of wheat hybrid vigor can greatly increase wheat yi...
