Abstract

The invention discloses an SSR molecular marker method for identifying a foxtail millet variety and application, and belongs to the technical field of plant variety identification. The method comprises the steps that foxtail millet DNA is extracted, a PCR amplification reaction is performed through the foxtail millet DNA and 5 pairs of SSR core primers, and after electrophoresis detection is performed, the foxtail millet variety is identified according to an electrophoresis detection result; the nucleotide sequences of the SSR core primers are shown as SEQ ID NO.1-10. According to the method, the foxtail millet variety can be effectively distinguished, and an important way is supplied to further identification of a large number of the foxtail foxtail millet varieties.

Description

technical field [0001] The invention relates to an SSR molecular marker method and application for identifying millet varieties, belonging to the technical field of plant variety identification. Background technique [0002] Millet is a crop of the genus Setaria in the Gramineae family. It has physiological characteristics such as short growth period, drought tolerance, and barren tolerance. It is widely distributed in the temperate and tropical regions of Eurasia. It is one of the main cultivated crops in the middle and upper reaches of the Yellow River in China. At the same time, the nutritional value of millet is extremely high, rich in amino acids, proteins, vitamins and trace elements such as calcium, copper, iron, zinc, selenium, iodine, magnesium, etc., and its nutritional and health effects are also very significant. For many years, breed identification was based on morphological markers. Although this method is simple and economical, it has a long cycle, high cost,...
