Abstract

The invention discloses an establishing and screening analysis method for a panicum miliaceum ethylmethylsulfone (EMS) mutant library, and belongs to the field of agricultural breeding. According to the method disclosed by the invention, a technology platform of panicum miliaceum EMS mutagenesis is constructed by screening of an optimal concentration of EMS-processed Yixuan red panicum miliaceum seeds; 103 mutant plant lines are found after obtained 2333 M2-generation plant lines are planted, morphological characters include a leaf color, a leaf type, a plant height, fertility, an ear type, anear color and a grain color, and the mutation frequency is 4.4%; and the mutant library with abundant phenotypes is established, and the mutant library can provide abundant mutant resources and novelgermplasm for functional genomic research and breeding of the panicum miliaceum.

Description

technical field [0001] The invention belongs to the field of agricultural breeding and relates to the construction of a broomcorn mutant library, in particular to a method for establishing a mutant library by EMS induction for broomcorn broomcorn. Background technique [0002] Millet (Panicum miliaceum L.) belongs to the annual Poaceae Panicum, an allotetraploid whose chromosome number is 2n=4x=36. , the characteristic miscellaneous grain crops mainly cultivated by people in semi-arid areas and ideal multiple crops. After the millet is shelled, it is called yellow rice. It is rich in various proteins, starch, fat, etc. needed by the human body. It has high nutritional and health value, and can be processed into a variety of foods to prevent and treat allergies, obesity and other related diseases; in addition, Its stalks and grains are also high-quality livestock forages. Therefore, millet plays an important role in meeting the diversified needs of public food consumption an...
