Method for breeding Yuanhongyu radishes

The invention discloses a method for breeding Yuanhongyu radishes. The method includes carrying out on test-cross and self-cross selective breeding on first female parents and first male parents overeight generations in four continuous years to obtain Nanzhangyuanhong 2A-3-3-2-3-5, namely Nanzhangyuanhong A, with the sterile rate stabilized at 100%; selectively breeding maintainer-line Nanzhang 2B-3-3-2-3-5, namely Nanzhangyuanhong B; hybridizing second female parents and second male parents to obtain first-generation hybrid radish varieties 'Yuanhongyu', namely the Yuanhongyu radishes. The first female parents are three male sterile plants without pollen in flowering periods, and the first male parents are fertile plants of 'Nanzhangyuanhong' varieties. The second female parents are theNanzhangyuanhong A, and the second male parents are 'Qiyehong' varieties. The method has the advantages that Yuanhongyu radish plants can robustly grow, have broad leaves and bright red and round fleshy roots, and nearly halve
