Method for breeding sightseeing-type white flower brassica napus

Abstract

The invention provides a method for breeding sightseeing-type white flower brassica napus. According to the method, an introduced white flower strain 'Su Yinhua No.1' of the Agricultural Science Research Institute of Taihu Lake, Jiangsu Province is taken as a female parent to cross-fertilize with a 'Yanyouza No.3' male parent H800-1 to obtain F1, then self-crossing is performed for 6 generations to obtain a pure strain, each generation is subjected to quality analysis, each generation is selected according to the standards of white, early flowering and high oil, rational cultivation is performed, after self-crossing is performed for 6 generations, the novel sightseeing-type white flower brassica napus variety is obtained through selection. The novel variety has the following advantages that 1, the petals are large and white, the flowering period is long, the number of flowers is large, the plant height is more than 160 cm, and the variety is resistant to pests and diseases; 2, the resistance to pod cracking is good, 180 kg or above rapeseeds are produced per mu, the oil content of the rapeseeds is 42%, the cake glucosinolate content is 15 micro mol / g or less, the erucic acid content is 1% or less, and the oleic acid content is 43%.
