Embodiment Construction

[0038] The technical solutions of the present invention will be described below in conjunction with the accompanying drawings and embodiments.

[0039] A method for de novo domestication of desert plant Sapona based on population polymorphism, comprising the following steps:

[0040] Step 1. Sample collection sites and regional divisions of Sapona populations: According to the distribution of Sapona in the wild, according to latitude and longitude, altitude, precipitation, temperature and climate conditions, select wild Sapona populations in multiple locations, and the interval between populations should be at least 50km; the sampling points are distributed in the arid areas of Northwest China and Northeast China, basically covering the distribution range of wild Sapona;

[0041] According to the geographical location, Tiegai Township (100.569°, 36.167°), Dulan (98.124°, 36.306°), Jingtai (104.147°, 37.367°), Shapotou Water Field (105.017°, 37.465°), forehead rest Ke (107.523...

Abstract

The invention relates to the technical field of domesticating desert plants from the beginning, in particular to a method for domesticating desert plant agriophyllum squarrosum from the beginning based on population polymorphism. The method comprises the steps that phenotypic variation caused by soil type, slope, climate and hydrological environment difference is excluded through homogeneous garden experiments; morphological or phenotypic differences formed by genetic differentiation is screened out through phenotypic data determination of wild agriophyllum squarrosum; the optimal natural growth condition influencing the heritable phenotype of the agriophyllum squarrosum is determined by combining the meteorological factor data of the agriophyllum squarrosum group of the origin; and groupgenetic evaluation is carried out on domesticated high-quality germplasm resources, and large-area popularization and demonstration of the germplasm resources are determined. According to the method for domesticating the desert plant agriophyllum squarrosum from the beginning based on population polymorphism, a genetic database of germplasm resource populations is constructed for the first time, gene flow among the populations is accelerated through the homogeneous garden experiments, and the adaptability of crop target phenotypes to the climate is improved; and the traditional time-consumingand labor-consuming artificial hybridization process is changed, and various risks caused by a transgenic technology are further avoided.

Description

technical field [0001] The invention relates to the technical field of de novo domestication of desert plants, in particular to a method for de novo domestication of desert plants based on population polymorphism. Background technique [0002] Among the more than 400,000 known species of plants, no more than 100 have been successfully domesticated, and only 15 have become major food crops. Among them, the three major crops of rice, wheat and corn account for as much as 50%. These major food crops have poor adaptability to climate change, and about one-third of the grain production is affected by it every year. In order to improve this situation, FAO (Food and Agriculture Organization of the United Nations) pointed out in "Combating Climate Change: The Role of Genetic Resources for Food and Agriculture" that it is necessary to screen and domesticate small crops and wild species that can adapt to climate change, and improve the gene bank of plant genetic resources , to protec...
