[0034] Example 1, Breeding "Main Inflorescence Polygonal" Brassica napus Varieties
[0035] 1. Discovery and Breeding of Rapeseed Lines with “Multiple Angular Main Inflorescences”
[0036] In 2004, a mutant single plant with abnormally many horns in the main inflorescence was found in the breeding materials. After selfing and directional selection for many years, a new line 12R1402 with stable "multi-cornered main inflorescence" was bred from the offspring of the mutant strain. The maximum number of effective siliques in the main inflorescence of the strain is 300, with an average of about 180. A new strain 12R1402 with stable characteristics of "polygonal main inflorescence" was bred, and it was preserved in the General Microorganism Center of China Committee for Microbial Culture Collection (CGMCC for short, address: Beichen West Road, Chaoyang District, Beijing) on April 8, 2016 No. 1 Courtyard No. 3, Institute of Microbiology, Chinese Academy of Sciences, Zip Code 10010...
