Culture method for perennial trititrigia

Abstract

The invention discloses a culture method for a perennial trititrigia, which includes the following steps: (1) in overwintering period, a greenhouse is built in an Elytrigia elongata-sowing region, filament lamps start to be used for lighting in late February, and Elytrigia elongata ear and bloom in late April; (2) 'Lankao Aizao 8' plants are entirely castrated, transplanted into flowerpots, put into the Elytrigia elongata greenhouse and freely pollinated, and thereby hybrid first-generation seedlings F0 are obtained; (3) in early June, the ears of the F0 are dried in the sun, and are threshed, stored and prevented from being eaten by insects according to hybridized combination; (4) in early September, F0 seeds are sowed in sand trays and put into an illuminating incubator to grow seedlings; (5) in late September or early October, the F0 seeds are transplanted into a net house, tiller and develop, and thereby F1 seedlings are obtained; (6) in late November, chromosome doubling is carried out on the F1 seedlings indoors, so that the F1 seedlings can become amphidiploids, the F1 seedlings are transplanted into the field after doubling, and thereby the perennial trititrigia is obtained. The culture method synthesizes a new perennial trititrigia species hybridized with wheat and Elytrigia elongata.

Description

technical field [0001] The invention relates to a method for breeding crops, in particular to a method for cultivating perennial tritium. Background technique [0002] At present, with the rapid development of our country's economy, the reduction of land, the increase of population, the shortage of water resources, the change of ecological environment conditions and the variation of organisms all have a serious impact on the development of agricultural production. To ensure the safe and effective supply of food in our country, we can only rely on scientific and technological progress, cultivate better crop varieties, and greatly increase the yield per unit area of ​​crops. To breed new varieties of crops, we must have good germplasm resources. Wheat is the main food crop in my country, and more than 40% of the urban population in the country feeds on wheat. For a long time, my country's wheat varieties have no breakthrough in yield, poor quality, weak disease resistance an...

Problems solved by technology

Elytrigia elongatum is a perennial herbage, belonging to the genus Elytrigia, with a plant height of about 150 cm, thick and narrow leaves, and an ear length of about 50 cm. It has many flowers, well-developed root system, strong cold resistance, high resistance to wheat bar, leaf and stem rust, and 70 chromosomes (10 ploidy). In common wheat, a new variety of wheat can be synthesized. However, the relationship between Triticum and Triticum is far away, and it is not easy to hybridize and produce fruit.
