Abstract

The invention discloses a breeding method of a purple-leaf erect panicle type giant embryo glutinous rice variety, belonging to the technical field of special rice breeding. The method takes a purple-leaf rice variety, an erect panicle type rice variety, a giant embryo rice variety and a glutinous rice variety as parents; control genes of four characters including purple leaves, erect panicle, giant embryo and glutinous property are gathered into the same rice variety by hybridization, multiple-crossing and screening of all the target characters, so that the special purple-leaf erect panicle type giant embryo glutinous rice variety is bred. The seeds of the variety are high in propagation speed and production purity and high in yield; the obtained rice has the glutinous property and the giant embryo character and is high in nutritional ingredient content.

Description

technical field [0001] The invention specifically relates to a method for breeding glutinous rice varieties with purple leaf erect panicles and giant embryos, and belongs to the technical field of special rice breeding. Background technique [0002] The purple leaf trait can be used as a marker trait in rice seed propagation or production to remove mixed plants and improve the purity of seeds and rice produced. The erect panicle type rice has a reasonable panicle population structure, superior ecological conditions such as canopy light intensity, temperature, and humidity, which is conducive to photosynthesis, improves fertilizer tolerance and lodging resistance, and increases outcross seed setting rate, thereby increasing yield. Giant embryo rice is rich in γ-aminobutyric acid, minerals, amino acids, vitamins and other natural nutrients and physiologically active substances. Red rice is rich in many nutrients, especially iron, which has the effect of nourishing blood and p...
