Abstract

The invention belongs to the technical field of rapeseed breeding, and discloses a breeding method of double main stem semi-dwarf brassica napus. The breeding method includes using ethylmethane sulfonate to mutagenize seeds of the inbred line of brassica napus, selecting double main stem tall plants to perform selfing, and selecting double main stem semi-dwarf plants to perform selfing; cultivating haploid plants, and performing doubling treatment to obtain the population of double main stem semi-dwarf brassica napus; and performing field identification, and obtaining the double main stem semi-dwarf brassica napus. The provided double main stem semi-dwarf brassica napus has the traits of double main stalks and semi-dwarf stems, so that lodging problems can be solved, the yield and qualityof the brassica napus can be enhanced, mechanized harvesting can be realized, and the overall efficiency of the brassica napus can be increased; EMS mutation is performed on the brassica napus, so that natural mutation rate of organisms can be increased; the method is simple and easy to operate and strong in specificity; and certain bases on DNA can be located through mutation, so that progenies can be easily and stably obtained through inheritance.

Description

technical field [0001] The invention belongs to the technical field of rapeseed breeding, in particular to a method for breeding double-main-stem semi-dwarf Brassica napus. Background technique [0002] At present, rape is an important edible oil crop in my country. It is mainly planted in the Yangtze River Basin and adjacent areas. It is the main winter fallow crop. The annual planting area is over 100 million mu, and the annual total output is over 10 billion Kg. It ranks first in the world in terms of area and total output. First. In my country, domestic rapeseed can produce more than 4 million tons of rapeseed oil every year, accounting for more than 40% of the domestically produced vegetable oil, accounting for nearly 20% of the total domestic vegetable oil consumption, and rapeseed oil accounts for 19% of the edible oil consumption of residents. In addition to rapeseed being used for oil extraction, the residue after oil extraction from rapeseed commercial seeds can al...
